Seasonal dynamics of NDVI among the maple species Seasonal dynamics of NDVI among the maple species Ignatova Maria A. 1, Kozlovsky Boris L. 1, Dmitriev Pavel A. 1, Fedorinova Olga I. 1, Dmitrieva Anastasiya A. 1, Varduni Tat'yana V. 1 1Southern Federal University, Rostov-on-Don, pdmitriev@sfedu.ru Abstract The paper attempted to use a hyperspectral camera under controlled conditions of a laboratory experiment to obtain unique curves of seasonal dynamics of NDVI values, allowing to identify the maple species. The objects of study were samples of Acer campestre L., Acer negundo L. and Acer saccharinum L. The maple leaf was surveyed in the laboratory using a Cubert UHD-185 hyperspectral camera under artificial light. To monitor the results, the content of chlorophyll was determined by a spectrophotometric method. Studies were conducted during the growing season of maples from the phenological phase of "full leaf unfolding" to the phenological phase of "the beginning of autumn leaf coloring. It is established that the seasonal dynamics of the NDVI value is similar to the dynamics of chlorophyll a, calculated by the spectrometric method. Empirical NDVI regression lines in all three maple species are synchronous at most survey times, especially in the maximum and minimum zones. However, the difference between NDVI maple species is not as drastic as in chlorophyll a, although in most survey periods the NDVI value of A. campestre is higher than that of the other two species of maples. We assume that the NDVI signature cannot be used to separate species of the genus Acer. However, to identify genera that vary significantly in phenology, the use of NDVI signature is quite possible.

Analysis of the flora of the experimental steppe fallow in the Botanical Garden of the Southern Federal University Analysis of the flora of the experimental steppe fallow in the Botanical Garden of the Southern Federal University   Shmaraeva A.N., Shishlova Zh.N., Kuzmenko I.P., Kazeev K.Sh., Makarova L.I. Southern Federal University, Rostov-on-Don, Russia; anshmaraeva@sfedu.ru   Abstract. The permanent study area (experimental steppe fallow) was organized on the territory of the Botanical Garden of the Southern Federal University on the site of arable land in 2016. The area of the permanent study area is more than 700 sq. m. The steppe fallow is located in the western part of the Botanical Garden on the watershed between the Temernik River and the Sukhoi Chaltyr Beam. The indigenous vegetation of the territory of the Botanical Garden was a fragment of the Azov steppe dominated by small-turf grasses before its creation in 1927. The task of the permanent area is a comprehensive study of the process of restoring fallow lands of the steppe zone. The research is carried out by the staff of the Department of Ecology and Nature Management and Botanical Garden of the SFedU. As a result of monitoring the process of restoration of the steppe fallow, it was found that in the sixth year of demutation, the community is in a transitional state from the weedy stage to the rhizomatous stage. This is confirmed by the species composition of the community, the biomorphological, hydromorphological, phytocenotic structure of the flora. 85 species of seed plants from 27 families and 68 genera were registered in the steppe fallow community in 2021. The range of life forms of the fallow flora is quite diverse. It is significantly dominated by herbaceous plants (90,6 %), including the proportion of annuals is 34,1 %, biennials – 20,0 %, perennials – 36,5 %. Among herbaceous perennials, a significant proportion are rod-rooted (25,8 %), root-springing (19,4 %), and rhizomatous (42,0 %) plants; turf plants are represented by only one species (3,2 %). In the hydromorphological structure of the fallow flora, the leading position is occupied by a group of mesophytes (76,5 %). According to the formation structure the flora of the steppe fallow is quite heterogeneous, 5 phytocenotypes have been identified in its composition. The group of weeds is the most numerous in terms of the number of species (71,8 %). The peculiarity of the process of demutation of the steppe community is that the natural process of recovery is complicated by the influence of the introduction activity of the Botanical Garden and the influence of the surrounding urban environment.

The buffer capacity of Chernozem ordinary carbonate of the Rostov region Goncharova Lyudmila Yurievna Southern Federal University, Rostov-on-Don, Russia Abstract: The work is devoted to the study of some indicators of the buffer capacity of ordinary calcareous chernozems of the Rostov region. Buffer capacity is an important element of soil fertility stability. It should be taken into account in chemical reclamation, as well as in the environmental assessment of soils. The purpose of the work is to determine the buffer capacity and some of its indicators in ordinary calcareous chernozems of the Rostov region It is established that ordinary calcareous chernozems have high resistance to the acidification, which is due to their physical and chemical properties and soil formation factors. During acidification, the greatest buffering area and the greatest stability is established for the Chernozem of the agrobiostation (ABS) of the Southern Federal University "Nedvigovka". It is explained by the higher content of humus and carbonates. Chernozems of the Botanical garden of the Southern Federal University are more resistant to alkalinization in comparison with chernozems of the ABS, which are lighter in texture. When alkalizing all soils are characterized by the same type of chemical reactions that neutralize the alkali added to the soil. Recorded values of 9.0

Some patterns of enzyme activity in various soil zones of urban landscapes of Sumgait Eng.  Some patterns of enzyme activity in various soil zones of urban landscapes of Sumgait Bagirova Chinara Z., Nadjafova Samira I. Institute of Microbiology, National Academy of Sciences of Azerbaijan; nadjafovas@yahoo.com Abstract: The features of the metabolic processes of transformation of the organic and mineral components of the soil are determined mainly by the complex of soil enzymes, the abundance and qualitative composition of the microbiocenosis. The activity of soil enzymes is an additional diagnostic indicator of soil fertility and its changes under anthropogenic impact. Studies of the activity of soil enzymes in various zones of the city of Sumgait - a large industrial center in which the petrochemical and oil refining industries are concentrated. The results of field studies showed that the activity of soil enzymes was not the same in different zones of the city of Sumgait. Significant differences in the catalase activity of soils of roadside and industrial zones and soils under parks have been established. With technogenic pollution, the functional activity of soil microorganisms is significantly reduced. In comparative terms, the activity of all soil enzymes is most suppressed in industrial zones, and to the least extent in park zones. The analysis shows that the technologically polluted soils of the industrial city of Sumgayit are characterized by weak stability of soil enzymes. These indicators reflect the specificity of pollutants, the degree of contamination, the nature and intensity of biological processes in soil affected by industrial impacts - industrial and transport emissions. The research results can be part of the database for an objective assessment of the soil cover of urban landscapes in Sumgait, to prevent the deterioration of their environmental functions, for the development of the scientific basis for the use of microorganisms in technologies for cleaning and increasing the fertility of urban soils.

Comparative analysis of methods for determining the particle size distribution of soils Eng. Comparative analysis of methods for determining the particle size distribution of soils Shkuropadskaya Kristina V., Pshenichnaya Alyona A., Boldyreva Veronika E., Morozov Igor V. Southern Federal University, Rostov-on-Don, Russia Abstract: The aim of the study is a comparative analysis of the results of determining the particle-size distribution of soils obtained by various methods: the field wet method, the pipette method, and also regulated by international (ISO 11277: 2009) and interstate (GOST 12536-2014) standards. Investigations of the particle-size distribution for ordinary calcareous chernozems have shown that the causes of inconsistencies in the analyzes results of the same soil samples using the pipette-method and the areometric method according to GOST 12536–2014 and ISO 1127762009 are exclusively associated with different approaches to preparing soil samples for laboratory tests. First of all, the analyses data are depended on the ratio of the soil sample mass and the dispersant volume.  

Immunological characteristics of thymus in guinea pig Eng. Immunological characteristics of thymus in guinea pig Evstropov Vladimir M.   Don state technical University, Rostov-on-Don, Russia Abstract:  It is known that different subclasses of thymus cells can perform different immunological functions. This is largely due to the maturity of thymocytes. Given the fact of age-related involution of the thymus and the significant role of the thymus gland in T-cell maturation, as well as the widespread use of guinea pigs as various experimental immunological models, the aim of the study was to study some subclasses of immunological significance in guinea pigs of different ages. in animals of different ages (the first group - the age of 3-4 weeks, the second group - the average age of 3 months). The thymocytes with peanut agglutinin receptors (PNA + cells) in the thymus of these guinea pigs were studied; E-ROCK identified by spontaneous rosette formation with rabbit erythrocytes; EAC-ROCK - in rosette formation with rabbit erythrocytes coated with antibodies and complement; Tµ thymocytes — by rosette formation with bovine erythrocytes (EA-PO) loaded with an IgM fraction of specific antibodies, and Tγ cells — by rosette formation with bovine erythrocytes loaded with an IgG fraction of specific antibodies. It was shown that to characterize age-related differences in guinea pig thymus, methods can be used to determine in the thymus gland cells of various subclasses that have immunological significance, in particular, Tγ cells and PNA + cells.

The yield of soybean varieties Kazachka erosion-dangerous slope depending on the method of basic soil treatment and mineral fertilizers Rychkova M. I. Mishchenko A.V. Federal Rostov agricultural research center, Rassvet village, Russia, E-mail: rychkova-1980@list.ru Annotation: The results of three-year field studies on the influence of methods of basic tillage and mineral fertilizers on the yield of soybean varieties Kazachka, obtained in the conditions of erosion-dangerous slope of ordinary carbonate chernozems (according  WRB, 2014, – Haplic Chernozem) of the Rostov region. Studies have found that in the conditions of erosion-dangerous slope an effective way of basic soil treatment in the cultivation of soybean varieties Kazachka is chisel and the introduction of an increased level of mineral fertilizers norm N84P30K48 (162 kg d. V. per 1 ha of crop area). At the same time, the highest indicators of productive moisture reserves in the soil and yield increase are formed-0.38 t/ha. Chiseling contributed to an increase in the payback of 1 kg of fertilizers by an increase in yield by 0.13-0.35 kg/kg in comparison with plowing.

Architectonics of the kidneys in connection with frost resistance Kidneys, like seeds, are of great importance in preserving plant life, especially in adverse environmental conditions. The structure of the kidneys consists of tissues and parts with varying degrees of thermal conductivity. A method for assessing the resistance of kidney to frost is proposed, depending on the internal structure of structures and location in space.

Entry of Zn and Cd from soil into herbaceous plants of the Asteraceae and Poaceae families Abstract: Environmental heavy metals pollution is one of the most pressing problems of nowaday ecology. Heavy metals are not subject to biodegradation and tend to move along the food chain, thereby threatening the animals and humans health. The aim of the work was to study Cd and Zn accumulation in different wild-growing herbaceous plants species of the Asteraceae and Poaceae families under long-term technogenic pollution. Ecological monitoring of the impact zone of the city of Novocherkassk, subjected to many years of technogenic pollution, was carried out. In plants growing in a 5 km zone around Novocherkasskaya power station, contamination with the studied elements was revealed. The soils of monitoring sites located in the prevailing north-west direction of winds are subject to the greatest pollution. The dependence of the content of Zn and Cd in the herbaceous plants of the Asteraceae and Poaceae families on the distance to the source of the technogenic load was established. The selectivity of metal accumulation by the studied species of herbaceous plants at various levels of technogenic pollution was revealed. Plants of the Asteraceae family accumulate the studied elements mainly in the aboveground part, Poaceae are characterized by a greater accumulation of metals in the root system. The least resistant to the input of pollutants from the soil is the Achillea nobilis. Poa pratensis has the highest resistance to Zn and Cd pollution by the combination of assessment indicators. Cd has a higher mobility in soils than Zn, which leads to a higher level of plant pollution with this element. The particle size distribution of the soil also has a significant effect on the availability of metals to plants.

Immunological phenomenon of physical antigen-specific interaction of mononuclear cells with granulocytes in vitro Evstropov Vladimir M. Don state technical University, Rostov-on-Don, Russia Abstract:  Currently, only some aspects of the physical contact antigen-specific interaction of lymphocytes with granulocytes have been described (5), but meanwhile it is known that not only various subpopulations of lymphocytes, but also macrophages play a leading role in the formation of specific (adaptive) immunity. In recent years, neutrophils have also become regarded as cells involved in the recognition of a pathogen; therefore, the physical interaction of these cells, which are excorded from the immune system, in the presence of a causally significant antigen in vitro is of undoubted interest. According to some researchers, to study a specific cellular immune response as a criterion for assessing the effectiveness of immunization, it is advisable to use laboratory methods in vitro using specific antigens [7]. The aim of this work was to study the feasibility of assessing the indication of specific immunity in vitro by characterizing the physical antigen-specific interaction of mononuclear cells with granulocytes isolated from rat blood immunized with staphylococcal disintegrant in the presence of incomplete Freund's adjuvant. In this case, the quantitative level of rosettingformation mononuclear cells interacting with three or more granulocytes in vitro in the presence of this antigen was evaluated. The results of the study showed an increase in the quantitative level of rosetting mononuclear cells, compared with the same indicator of non-immune rats of the control group. The paper considers the possible participation in the implementation of this immunological phenomenon of subpopulations of peripheral blood T-lymphocytes (naive T cells, CD45RA-positive effector cells, antigen-reactive T cells), as well as NK cells, monocytes and neutrophils. It is assumed that this method can be used to detect an immune response, however, the molecular mechanism of this immunological phenomenon and its immunological classification (attribution to the cellular or cell-mediated type of reaction involving cell-fixed antibodies) needs further study.

On the biological degradation of white phosphorus On the biological degradation of white phosphorus   1 Institute of Organic and Physical Chemistry named after A.E. Arbuzov. Kazan Scientific Center of the Russian Academy of Sciences. Arbuzov St., 8. Kazan, 420088. Republic of Tatarstan. Russia. E-mail: mindubaev-az@yandex.ru 2 Kazan (Volga Region) Federal University. University St., 18. Kazan, 420008. Republic of Tatarstan. Russia. Abstract For the first time different taxonomic groups of microorganisms (fungi, Streptomyces and bacteria) are inoculated on culture medium containing white phosphorus as the single source of phosphorus. On these media microorganisms grew and have not experienced phosphorus starvation. It is the world's first example of the inclusion of white phosphorus in the biosphere cycle of elemental phosphorus. The highest concentration corresponds to 5000 times excess of MPC of white phosphorus in wastewater. The comparison of the sequences of ribosomal genes of the fungus, steadily metabolizing the white phosphorus, with sequences of the GenBank database, allowed us to identify this microorganism as a new strain of Aspergillus niger, to which we have assigned the number A. niger AM1. Inoculation of A. niger AM1 in medium containing just two sources of phosphorus (phosphate and white phosphorus) demonstrated that P4 does not exhibit toxic properties in relation to this microorganism. In the presence of white phosphorus it grows at the same rate as in the absence thereof. This is the only example of the lack of white phosphorus toxicity to a living organism. Our previous studies have demonstrated the absence of white phosphorus toxicity for Aspergillus niger AM1. However, the toxic properties of the substances are of different nature. It is of great interest to study the genotoxicity – a possible source of mutations. In the present work SOS-lux test has demonstrated genotoxicity of white phosphorus. This result is obtained for the first time – all the available literature sources reported no genotoxic properties of white phosphorus. Allium test showed the mitotoxic effect of white phosphorus on eukaryotic cells. A very interesting and unexpected result was the discovery of a mutant Aspergillus niger AM1. In comparison with an ancestral strain this mutant possesses an unusual morphology and grows more intensively in culture medium with white phosphorus. Three strains of A. niger, sent from the All-Russian collection of microorganisms, also showed much higher resistance to white phosphorus than bacteria. According to preliminary data, resistance to white phosphorus the A. niger is fixed in the genome.

Resource-saving elements of soybean cultivation technology on the slopes of the Rostov region Resource-saving elements of soybean cultivation technology on the slopes of the Rostov region Rychkova M.I., Gaeva E.A., Mishchenko A.V. Federal Rostov Agricultural Research Center, Rassvet. Е-mail: emmaksay@inbox.ru. Abstract. The article presents the actual results of research on the development of resource-saving elements of soybean cultivation technology, providing moisture saving, high productivity and soil protection from erosion. Two-year studies were carried out on the erosion-dangerous slope of the South-Eastern exposure of the Bolshoy Log beam, Aksai district of the Rostov region in the system of contour-landscape organization of the territory in 2017-2018. Studied two methods of primary tillage – otvalnuyu adopted for monitoring and chisel. Chisel tillage in the cultivation of soybean was performed by chisel plow. Dump processing was carried out with a plow blade. The mineral nutrition system included three backgrounds: natural fertility recommended by zonal systems and increased by half. It is established that to prevent possible erosion it is recommended to cultivate soybeans in the system of contour-band placement of fields. It is shown that the payback of the crop fertilizers on the version with the chisel treatment of the soil is higher than on the dump. Increasing the dose of fertilizer in half reduces the payback of fertilizers by 18.9-19.4 %. It is revealed that the approved soil protection (chisel) tillage can significantly reduce the erosion processes – soil flushing by 22.9%, runoff – 10.0%, the cost of fuel and lubricants-18.8%, increase the accumulation of reserves of productive moisture in the soil with a more economical expenditure, yield – by 30.2 – 32.1%, conditional net income-up to 6.6 thousand rubles /ha, profitability-by 42.1%, recoupment of direct costs yield of 1.4 rubles per ruble in comparison with the same indicators at the dump plowing.

Location on the Caucasus Potentilla multi-advisable (Potentilla multifida L.) Location on the Caucasus Potentilla multi-advisable (Potentilla multifida L.)  O.N. Demina, L.L. Rogal'  Abstract: The paper describes the Gum-Bashi Pass, which is named after the homonymous right-bank tributary of the Kuban - the Mara River. The distribution of grass vegetation on the Gum-Bashi Pass, as on the whole Rocky Caucasus Mountains, is associated with vertical zonality or altitudinal belt ecosystems. The characteristic of indigenous subalpine vegetation is given: on gentle northern slopes and plateaus of the Rocky ridge formed lush grassy meadows; Petrophytic steppes develop on the steep slopes of the southern, southeastern, and southwestern exposures. The most common types of natural forage lands on the Gum-Bashi Pass are mountain meadow communities on mountain sod-podzolic, gray and brown forest soils, and meadow-steppe communities on leached and podzolized black soil. However, the main purpose of the work is to describe a new plant species, Potentilla multifida L., which we discovered for the first time in the territory of Karachay-Cherkessia, in the Rocky Ridge system on the Gum-Bashi Pass and confirming its growth in the Caucasus. In describing this species, it is mentioned that this herbaceous perennial reaches 40 cm in height. The leaves of the plant are green above and beloiclochic below, dissected into linear lobes. The flowers are small, on thin pedicels, pale yellow. The beginning of its flowering was recorded when the species was collected. A critical summary of references to this species and an indication of the need to describe a new Caucasian form is given. In conclusion, one more time focuses on the need for this description, studying the distribution of P. multifida in the Caucasus and its phytocenotic environment. The article is illustrated with a large number of photos.

Effect of different phytohormones on Austrian sage multiplication (Salvia austriaca Jacq.) Effect of different phytohormones on Austrian sage multiplication (Salvia austriaca Jacq.) Vasilchenko Elena V., Sereda Mikhail M., Varduni Tatiana V. Southern Federal University, Rostov-on-Don, Russia  Abstract: The influence of phytohormones such as 6-benzylaminopurine, naphthylacetic acid and indole-3-acetic acid on the Austrian sage multiplication (Salvia austriaca Jacq.) in an in vitro culture is discussed in the paper. Austrian sage is the medicinal, essential oil, melliferous and ornamental steppe herb, included in the Red List of the Rostov region. The study was conducted in the laboratory of cellular and genomic technologies of plants of the Botanical Garden. Seeds from the collection of the Botanical Garden of the Southern Federal University were used as the primary explant. For cultivation the Murashige and Skoog medium was used. Murashige and Skoog medium without the addition of phytohormones was used as a control. Evaluation of the multiplication efficiency was carried out after 21 days. The multiplication factor was calculated as the number of new shoots. The highest multiplication factor was observed in the medium with the addition of 0.5 mg / l of 6-benzylaminopurine and 0.1 mg / l of naphthylacetic acid. This concentration of phytohormones is recommended for micropropagation of Austrian sage. The concentration of auxins (IAA and NAA) 0.3 mg/l leads to a decrease in the efficiency of Austrian sage multiplication. The height of shoot was approximately the same and no statistically significant differences were found on all tested mediums. It should be pointed out that with a greater concentration of phytohormones physiological abnormalities was observed.

Methods of soil fertility preservation on eroded slopes of Rostov region Methods of soil fertility preservation on eroded slopes of Rostov region Gaevaia Е.А. Federal Rostov Agricultural Research Center, Rassvet. Е-mail: emmaksay@inbox.ru. Abstrac: Тhe Studies were carried out in a multifactorial stationary experiment in 1991-2018 years. the Experiment is located on the slope of the beam of the Big Log of Aksai district of Rostov region. The soil of the experimental site is ordinary heavy loamy Chernozem on loess-like loam, medium-eroded. In the experiment studied two crop rotation zernopererabotki (I) and sertralineprograms (II), and three levels of organic-mineral system of fertilizers («0» – natural fertility; «1» – cattle manure 5 t + N46P24K30 and «2» – cattle manure 8 t + N84P30K48 1 hectare). The aim of the study was to study the balance of humus depending on the design of crop rotations located on the eroded slopes of the Rostov region, to identify ways to preserve soil fertility at the initial level and increase it. As a result of the research, the amount of washed soil was determined. The importance of plant residues in the accumulation of humus is shown. It is established that the intensive use of agricultural land in the Rostov region without fertilizer leads to a reduction in the humus content in the soil. The role of perennial grasses in reducing soil flushing by 35.6% was studied. It is shown that the long-term use of organic fertilizers in crop rotations at a dose of 5 tons of cattle manure and N46P24K30, as well as the introduction of 20% of perennial in the crop rotation allows to maintain a positive balance of humus at the level of (+35 kg/ha) in the grain-grass crop rotation. Increasing the dose of fertilizer to 8 tons of cattle manure and N84P30K48 contributes to the accumulation of humus up to (+100 kg/ha) in the grain crop rotation. The possibility of replacing organic fertilizers with 1-2 t/ha of wheat straw using compensatory doses of nitrogen fertilizers is shown.

To the future without poliomyelitis: the state of the epidemic, vaccination issues (review) To the future without poliomyelitis: the state of the epidemic, vaccination issues (review) Belova Olga Evgen’evna  FSRI SRC VB «Vector», Koltsovo, Novosibirsk reg., Russia  Abstract: Polio is a highly contagious viral infection that affects mainly children under five years of age, which can lead to paralysis or even death. Damage to the nervous system is manifested by fever, pain in the limbs, then peripheral irreversible paralysis. In severe cases, paralysis of the respiratory muscles can occur, which causes death. The transmission mechanism is predominantly fecal-oral. The only way to combat polio remains vaccination. The vaccine provides the development of long-term humoral and local immunity. The purpose of this work is to analyze the epidemiological situation of poliomyelitis in the world 31 years after the adoption of the Global Polio Eradication Program, and to compare the characteristics of live and inactivated polio vaccines. Issues related to the use of live oral polio vaccine and the need for its phased withdrawal from circulation, the problem of vaccine-related polioviruses and vaccine-associated paralytic polio are considered.

Features of the geographical structure of the Krivoy Rog urban flora (Ukraine) Abstract: To identify the specificity of the formation of any flora and its relationship with other floras is possible using the geographic analysis. The aim of the work was to analyze the geographical structure of the spontaneous flora of Krivoy Rog city and to reveal the characteristics of its forming under the influence of urbanization. The object of research was all the species of higher plants, which spontaneously settled in the administrative borders of the city and its green zone. The geographical structure of the flora was understood as the inherent spectrum of geographic elements (arealogical groups). The analysis of the ranges of the species of the native fraction of Krivoy Rog urban flora was carried out on a zonal-regional basis, while the group of alien species was analyzed using the primary ranges of the species. Тhe geographic analysis reveals the autochthonous and allochthonous nature of the Krivoy Rog urban flora, its geographic connections at the level of high-ranking chorions: Holarctic, Palaearctic, Eurasian, Mediterranean.  In general, all the species belong to 7 basic and 2 transitional types and 25 geographic elements; alien species form the separate group. Identity and individuality of the city flora are determined by the species of the Black Sea type of the ranges, there are 147 ones (13,5%). A significant percentage of the alien species (30,66%) refers to the peculiarities of the modern florogenesis in urbanized territories; among these species an important role belong to representatives of the North American type of migratory elements (over 20% of the total number of alien species).  

Seventy years' experience of creation of the state protective forest strips in a steppe zone of Russia In a steppe zone of the European territory of Russia artificially created 8 state protective forest strips (SPFS) are located. Research objective: on the basis of analytical materials to carry out the assessment of a condition of SPFS of a steppe zone of the European part of Russia, to reveal their recreational potential. Materials and methods of a research: general information, creation history, ways and technologies of creation of SPFS, lesovodstvenny actions in them were studied and analyzed according to references and share materials. Information on existence and condition of SPFS in regions of a steppe zone of the European part of Russia was established according to the state forest register. For certain regions the recreational appeal of SPFS paid off.  In article the history of creation of these strips, since adoption of "The Stalin plan of transformation of the nature" from 20 оctober 1948 g is considered.  On this project in 15 years (1949-1965) it was planned to create 117.9 thousand hectares of SPFS, but actually works were finished in 1972. 4 water separate and 4 prirechnykh state protective forest strips were created.  Now the total area of SPFS in a steppe zone of the Russian Federation is 85.7 thousand hectares. At the same time more than 13% of their area are presented by not forest lands, and covered with forest vegetation are about 80%.  From tree species as a part of SPFS the Quércus róbur prevails, the second place is taken by an Fráxinus excélsior  and F. lanceolate, the third Ulmus pumila. It is established that more than a half of the spaces are occupied by middle-aged plantings, 16.6% – coming, 8.9% – ripe and perestoyny. The state protective forest strips have the recreational potential which increases in process of increase in a share of SPFS as a part of forest fund of the territory; and in process of decrease in the general woodiness of the territory.  The SPFS recreational value increases at increase in their availability (first of all transport) in comparison with other territory of forest fund.

Ecological-modifying effect of soil contamination with heavy metals on the contact interaction of human leukocytes Evstropov Vladimir M. Don state technical University, Rostov-on-Don, Russia Abstract: It is known that by assessing the intensity of the contact interaction of lymphocytes with granulocytes, we can detect the processes of preclinical carcinogenesis. Heavy metals have carcinogenic properties, and the interaction of lymphocytes with granulocytes, which characterizes the level of transforming cells, is reduced in people permanently residing in the city, compared to people in rural areas [6], apparently under the influence of increased of anthropogenic environmental pollutions. At the same time, the contact interaction of lymphocytes with granulocytes can be considered as a cytological phenomenon, which characterizes the functional state of leukocytes, in particular their locomotor and adhesive potencies. Based on the characteristics of various functional zones of the city of Rostov-on-Don, established on the basis of the determination of the total indicator of soil contamination with heavy metals (zinc, arsenic, copper, lead and nickel), we carried out a comparative analysis of the activity of contact interaction of leukocytes of various types (lymphocytes and granulocytes) among the residents of two functional zones of the city, who differ in the degree of soil contamination with heavy metals: with moderately dangerous and acceptable levels of contamination. The results of the study showed that the residents of the functional zone of the city with a moderately dangerous level of soil contamination with heavy metals, the intensity of the interaction of the studied leukocytes was lower than that of those living in the territory with an acceptable level of pollution. We assume that the revealed decrease in the intensity of contact interaction of leukocytes in people long-term living in areas whose soil is moderately polluted with heavy metals is caused by chromosomal abnormalities and transformation of leukocytes, in particular lymphocytes.

Biotechnologies of oil-polluted soil cleaning of the apsheron peninsula and integral indicator of their biological condition Nadjafova Samira I., Gasanova Zulfiya P., Ismaylov Nariman M. Institute of Microbiology, National Academy of Sciences of Azerbaijan; nadjafovas@yahoo.com Abstract: Studies of technologically disturbed soils of the Absheron Peninsula were carried out through the integral indicator of the soil biological state (IPBS) in accordance with the scores of the most important informative properties of their biological state: enzymatic activity, hydrocarbon-oxidizing microorganism numbers, seed ratio of total hydrocarbon-oxidizing microorganisms to the total number, phytotoxicity, allowing to evaluate the potential of self-cleaning ability of landscapes and choose the way of their rehabilitation. Processing the results of the experiments showed that there is a negative relationship between the indicators of the degree of anthropogenic load with soil biogenicity: r = -0.75 ± 0.04. The system analysis of biological indicators and IPBS calculated on their basis of technologically disturbed soils of the Absheron Peninsula in the NGDU territories allowed them to be ranked according to the degree of resistance to anthropogenic pressure and ability to self-purification: Karadag district> Sabunchu and Khazar districts> Surakhani and Binagadi districts> Sabail district As a method of biological remediation, a biological preparation was used based on excess activated sludge from the Gosaninsky aerator station. The results of laboratory model studies have shown that the introduction of a biological product has a positive effect on the biological properties of the soil at both the microbiological and enzymatic levels.

Study of the influence of parkland of the Botanical Garden of the Southern Federal University on the parameters of the microclimate Study of the influence of parkland of the Botanical Garden of the Southern Federal University on the parameters of the microclimate A. S. Bezrukova, B. L. Kozlovskij, M. V. Kuropyatnikov Southern Federal University (SFedU), Rostov-on-Don Abstract: Rostov region refers to areas with uncomfortable conditions. Therefore, to create a comfortable environment requires special events. In cities, forest parks, parks, gardens and squares create a favorable microclimate. Analysis of the literature shows that the influence of green spaces on the microclimate of southern cities is not well studied. The aim of the work was to assess the impact of the park of the Botanical Garden of the Southern Federal University on the microclimate. As the object of the study were taken different in species composition plots of the park of the Botanical Garden of SFedU. As part of the study, measurements were made of the temperature and humidity of the air using the UNI-T UT333 device at a height of 1,3 m from the soil surface, as well as the surface temperature using the UNI-T UT320D device. The measurements were carried out on pedestrian alleys and paths. In the course of the research, it was established that the park stands effectively affect the microclimate parameters (air and surface temperature, air humidity), changing them in the direction of more comfortable. It is proved that there is a reliable difference between the values of the measured parameters at open space and in the park area with a confidence level of 99,9 %. The greatest effect of changes in air temperature and road network surfaces is observed at noon, then it decreases. The absolute difference in humidity between the park and open spaces during the day does not change. The ameliorative effect of parkland on of surrounding areas is spread weakly. The degree of change of microclimate parameters does not depend on the species composition of woody plants growing on it.  

Catalogue of the rare and extinct plant's collection of the Rostov region in the Botanical garden of the Southern Federal University Catalogue of the rare and extinct plant's collection of the Rostov region in the Botanical garden of the Southern Federal University Shmaraeva Antonina N., Shishlova Zhanna N., Kuzmenko Inna P., Firsova Anna V. Botanical garden of SFU, Rostov-on-Don, Russia; anshmaraeva@sfedu.ru Abstract: The Botanical garden of Southern Federal University (BS) for more than 90 years of its existence turned into the center of the conservation of biodiversity of plants. From the moment of its creation the methods of an introduction of plants in a steppe zone were developed in the Botanical garden, woody and grassy plant's collections were formed. The BS modern collection fund is presented by 17 thematic collections and expositions of the outdoor and in closed greenhouses. One of priority problems of BS is preservation of rare species of regional flora ex situ, that is: in the collections and expositions. To these targets serve, first of all, the collection of rare and endangered species of plants of the Rostov region. When forming a collection the new knowledge and practical material received in the course of implementation of long-term projects on maintaining the Red List of the Rostov region are used. Now the collection of rare and extinct plants of the Rostov region contains 75 species of flowering plants (or 40% of total number of the protected seed plants of the Rostov region) from 28 families and 55 genuses, including 24 species included in the Red List of the Russian Federation and 6 species included in the Annex to the Red List of the Russian Federation. The grassy perennials, xerophytes, species of steppe ecology prevail in the collection; and in the geographical relation – the species, connected with the arid centers of origin. The species with category of a rarity 3 (rare), and category of a rarity 2 (reducing in number). are presented in the collection in more or less equal degree. Six species have category of a rarity 1 (being under the threat of extinction) and four species – category of a rarity 5 (restored).  

The change of absorbed bases composition in desert soils as an indicator of their evolution  The change of absorbed bases composition in desert soils as an indicator of their evolutionYuldashev G.1, Isagaliev M.T.1, Bezuglova O.S.2 1Fergana State University, Republic of Uzbekistan 2 Southern Federal University, Rostov-on-Don, Russia   The research is aimed to clarify the role of the capacity of the soil absorbing complex and the composition of cations in the evolutionary transformations of the irrigated desert soils. The object of research comprised the soils of large regions of oasis agriculture of the lower reaches of the Amu Darya and Central Fergana, where irrigated meadow, floodplain alluvial and irrigated meadow, oasis soils are distributed respectively. Considering the alluvial nature of the deposits on which the studied soils are formed, they can be attributed to the reference soil group Fluvisols (Fluvisols). Absorbed bases were determined by the Pfeffer method in Kruger modification. It was established that the studied soils are characterized by certain values ??of the absorption capacity and the ratio of cations in the composition of the soil absorbing complex, depending on the duration of irrigation and a combination of soil formation factors. At the same time, the average content of each cation in the composition of the soil absorbing complex is relatively stable for the soil. In the process of evolution, which occurs under the influence of agrotechnical and agromeliorative methods of using the soil, these indicators change slowly following the change in the grain size distribution. In general, the amount of absorbed bases increases with the increase in the cultivation of irrigated hydromorphic desert soils. The chemical composition of alluvial and alluvial-proluvial pedogenesis soils also influences the characteristics of soil formation in the desert zone and the specifics of their ameliorative characteristics. According to the content of Ca ++, Mg ++, K +, Na + as part of the soil absorbing complex, the potential capabilities of the soils and the efficiency of land reclamation are determined, measures are being taken to increase the fertility of irrigated soils.

The paper aims to assess the impact of urbanization on the quantitative characteristics and species composition of microbial communities of the urban soils of Rostov-on-Don. 10 soil samples characterized by a dramatically different level of anthropogenic impact and transformation have been studied. The microbial communities of the upper horizons of weakly disturbed natural soils (Haplic chernozem) were compared to those from the urbic horizons of the Technosols in the central part of the city. It has been shown that the process of urbanization leads to a fundamental change in the microbial communities of urban soils in the steppe zone. There is a decrease in species diversity in the microbial communities. In addition, in anthropogenically transformed soils there is an increased number of copiotrophic bacteria compared to weakly disturbed soils. The number of aerobic spore-forming bacteria of the order Bacillales decreases several times. The species composition also changes, which is manifested in the disappearance of typical species from microbial complexes of anthropogenically transformed soils. The proportion of rapidly growing species of bacteria (r-strategists) is increased in the microbial communities of urban soils, indicating that the soils are under stress. The stability of the soil ecosystem is impaired and this may lead to the loss of its ecological functions. In addition, an increase in the proportion of microorganisms with antioxidant pigments was observed in anthropogenically transformed soils.

Rare species of plants and fungi in the territories of protected natural objects of the Rostov region Rare species of plants and fungi in the territories of protected natural objects of the Rostov region Fedyaeva Valentina Vasilyevna1, Shmarayeva Antonina Nikolayevna1, Hibukhina Tatyana Yuryevna2, Shishlova Zhanna of Nikolayevna1, Kuzmenko Inna Petrovna1 1 Southern Federal University, Rostov-on-Don, Russia; vfedyaeva@gmail.com 2 Ministry of Natural Resources and Environmental Protection of the Rostov region, Rostov-on-Don, Russia   The formation of network of the especially protected natural territories (EPNT) is one of the most effective mechanisms of preservation of the natural complexes and objects in World practice, including biological diversity of plants. 82 EPNT with a total area of 233.49 thousand hectares operate in the Rostov region now, covering 2.31 % of its territory. It is much less than average World's level (8.8 %) and an than average Russia's level (13.6 %). In the course of the researches the biological diversity of plants and fungi was defined on EPNT of status category: «protected natural objects», including the species, engaged in the Red List of the Rostov region. The protected natural objects are the unique single natural objects and unique territories, having the area less than 100.0 hectares, representing scientific, educational, cultural and esthetic value. The protected natural objects are presented in 13 of 43 administrative regions of the Rostov region. The total area of the protected natural objects which are located in different parts of the area to the date 01.03.2018 is 1.07 thousand hectares which corresponds to 0.50 % of total area of EPNT, operating in the Rostov region. In recent years it was established, that in the territories of protected natural objects of the Rostov area 98 species of plants and fungi occur, which are included in the Red List of the Rostov region (35.9 % of the total number), including 26 species engaged in the Red List of the Russian Federation – 51.0 % of the total number of the «Red List» federal objects, growing in the territory of the Rostov region.  

Thermal desorption of petroleum products and heavy metals in soils of the Volgograd–Volzhsky agglomeration Thermal desorption of petroleum products and heavy metals in soils of the Volgograd–Volzhsky agglomeration Kaplya Veronika N., Okolelova Alla A., Korchagina Mariya P. Volgograd state technical University, Volgograd, Russia; veronikazaikina@mail.ru Abstract: Thermal desorption is used to accelerate the extraction of large amounts of high–molecular hydrocarbons (including petroleum products) from the soil. It was carried out under the influence of high temperatures and pressure in the autoclave MLS – 3020 U (SANVO, Japan) at 1.5 atm (122 ° C), and warmed in a dry oven SHS–80–01 at 170 ° C for 40 minutes . Purpose: to study the features of fixing petroleum products and heavy metals in agglomeration soils, changes in their concentration in the soil under the influence of high temperatures and pressure (thermal desorption). This article presents information on the content of petroleum products and heavy metals in light chestnut and alluvial soils of the Volgograd–Volzhsky agglomeration, and for the first time – changes in their content in the soil after thermal desorption. For the first time we used similar conditions for determination of heavy metals in soils. The concentration of petroleum products after thermal desorption in the soil increases by 1.22–1.50 times. The increase in the concentration of petroleum products after thermal desorption occurs due to the fact that a significant part of them, represented by light fractions, evaporates in the first weeks after entering the soil, and heavy fractions are sorbed by the mineral part of the soil, and as a result of desorption are released. The concentration of heavy metals after thermal desorption are almost twice less than their gross forms. We assume that the mobile fractions (acid – and water–soluble) at a given temperature and pressure evaporate, and as a result of desorption elements are released from the complexes.

Оценка основных кинетических параметров каталазы в почве Fariz Mikayilov Department of Soil Science and Nutrition of Plants of Agricultural Faculty of "Igdyr" University, 76000, Igdir, Turkey, fariz.m@igdir.edu.tr Abstract. Numerous studies have been carried out on the kinetics of enzymatic processes in soils in which the kinetic parameters Vmax and KM are determined using the Michaelis-Menten equation. The enzyme activity values for a short period of time from the start of the reaction are usually used as the value of the reaction rate. In contrast to these studies, we used analytical methods to determine the initial rate of the enzymatic reaction. Calculations are made for determining the values of the initial velocity and kinetic parameters of catalase in the soil. The conducted studies show the dependence of the accumulation of the catalase enzymatic reaction products from the incubation time at various concentrations of substrates in the soils of Konya province. It has been shown that the amount of the reaction products grows nonlinearly, moreover it is described by the most accurate and adequate model - a polynomial of the 4th degree. Using this model, the initial velocity values for each substrate concentration were calculated. The curves of the dependence of the initial rate of the catalase reaction in the soil from the substrate concentration for the soils of the Chumra region have a monotonous form. Thus, we were able to improve the accuracy of determining the initial reaction rate and the kinetic parameters Vmax and KM of the enzymatic reaction of hydrogen peroxide decomposition by catalase in real soil conditions.

At the same time, pollution was noted with two types of soil pollutants around oil fields and an oil and gas enterprise. According to the obtained results, it was noted that the degree of soil pollution by sources relative to the background in the gray-brown soils spread around the Kukdmalok oil fields was 10.3 g / kg; in meadow-alluvial soils common around the North Oknazar oil fields - 6.4; in takyr-meadow soils common around UDP “Muborakneftgaz” - 2.80; in gray-brown soils spread around the Uchkyzyl oil fields - 11.2; in takyr soils common around Kakaidi-2.4 oil fields; and in desert sandy soils around the Khovdak oil fields - 82.7 g / kg.  

Metabolomic profiling of soils of chronoseries of podzols of a sand quarry Metabolomic profiling of soils of chronoseries of podzols of a sand quarry K.V. Sazanova, E.V. Abakumov, D.Yu. Vlasov FGBOU St. Petersburg State University, 199034, St. Petersburg, University Emb. d.7-9   Abstract: Metabolic profiling of soil samples from the chrono-series of the Maluksinsky quarry was carried out: 1-2 years old, fresh sand lithostra with no signs of overgrowing and soil formation, the stage of self-overgrowing 15–20 years with emerging pine-tree and sod-podbur, the stage of self-overgrowing 30–35 years with embryo podzol, the stage of self-overgrowing 70 years with formed podzol and pine forest background soil near the quarry. Soil chronoseries are promising model objects in which the process of soil restoration can be observed in development within certain time intervals. Analysis of methanol extracts of the soil was performed using the GC-MS method. Metabolic profiling of soil samples from the chrono-series of the Maluksinsky quarry was carried out. Amino acids, fatty acids, organic acids of the Krebs cycle, polyols, sugars, sterols, diterpenes, and phenolic compounds were identified in the metabolic profile. The results showed the samples significantly differ in the content of low molecular weight organic substances. The greatest structural diversity of small molecules was found in samples from the upper horizon. Molecular diversity was achieved mainly due to the secondary plant metabolites are likely to leach out of the litter and higher plants. The profiles of the underlying horizons are more similar. In the sand dumps, the amount of organic matter was very low and the metabolic profiles of all horizons differed little. The obtained results expand the understanding of the biochemical composition of the soil, contribute to the understanding of the processes of pedogenesis and the structure of the metabolite network of soils.

Comparative ability to adapt vines on the Lower Don Eng: Comparative ability to adapt vines on the Lower Don Maltseva A.N. Botanical Garden of the Southern Federal University, Rostov-on-Don, Russia Abstract: Despite the blackberry widespread in the World, this crop in Russia is not paid enough attention. Industrial cultivation of blackberry is absent. During the last 15 years were published the results of a few studies. For the production of canned blackberries in sugar, Donconserv at Rostov-on-Don city use blackberries of imported raw materials (Poland or China). Therefore, the blackberries in our country can be attributed as underutilized crops. The steppe arid zone, in which the Botanical Garden of the Southern Federal University is located, characterized by a combination of heat excess with a relative lack of moisture. Since blackberry is liana, it was interesting to study several species of lianas and their ability to adapt to this climate. To the investigation were taken species: Rubus сanadensis L., Aktinidia argutaPlanch. Ex Mig. and Parthenociccus quinquefolia (L). Planch.  

Sheyko Elena A.1, Sytnikov Denis M.2 1 S.I. Georgievsky Medical Academy  of Vernadsky CFU, Simferopol, Russian Federation; lenasheyko@mail.ru 2 Odessa I.I Mechnikov National University, Odessa, Ukraine   Abstract: Anatomy-morphological, symbiotic and allelopathic peculiarities of four representatives of the Orchidaceae Juss., the Crimea geophyte species: Epipactis helleborine (L.) Crantz s. l., Dactylorhiza iberica (M. Bieb. exWilld.) Soo?, Epipactis persica (Soó) Nannf. s. l., Ophrys mammosa Desf. subsp. taurica (Aggeenko) Soo? were studied. Biochemical, physiological, microscopic methods of research and methods of statistic alanalysis were used. As a result of the conducted researches, the features of the localization of the endomycotrophic component, the dynamics of symbiotic and allelopathic relations at various stages of ontogenesis, the influence of edaphic factors on the degree of mycotrophy were revealed. It was established that in the rhizomatous orchid species the degree of mycotrophy is lower than in the fleshy root species. The dynamics of symbiotic relationships varied according to ontogenesis phases. Occurrence of the mycorrhizal infection decreases from juvenile to a generative stage in the studied species. As the degree of mycotrophy increases, the number of ovules and seeds in the capsule increases. By the means of qualitative histochemical reactions it was established that the dynamics of allelopathic interactions is due to the accumulation of lignin, pectin and phenolic compounds in the tissues of the primary cortex of the orchids` rhizome. When studying the hormonal complex of fungi associated with orchids, the ability to excrete auxins and cytokinins into the external environment was revealed. It opens the possibility of microorganisms impact on overall hormonal balance of plants, stimulating additional rooting of orchids, as well as to influence the germination of their seeds. It was defined that the reproductive strategy of the investigated species of orchids is determined by the degree of interaction with the mycorhizal fungi, the peculiarities of the growing conditions and the nature of the studied species pollination.   

Materials on moulting of Dice snake (Natrix tessellata) (Serpentes, Colubridae, Natrix) in mainland and island populations of the western coast of Middle Caspian The article presents data on a molting of the Dice snake (Natrix tessellata) on the western coast of the Middle Caspian. The sex and the age differences in the frequency of moulting and the duration of the intervals separating of them have been revealed. A general increase in molting frequency in individuals of the island population were established. Approximately at 30% of the dice snakes of continental populations on the recreationally transformed areas of the territory were marked moult violations, which were expressed a fragmented of the pull off of the skin. There was a strong positive correlation between the length of the intervals between molts and the length of the body of snakes.  

Heavy metals in soils and road dust in the Stoilo-Lebedinsky mining complex. The content of heavy metals and metalloids were investigated in iron ore, soils and road dustin surrounding the Stoilo-Lebedinsky mining complex of Kursk Magnetic Anomaly, where a lot of mining, metallurgical and other enterprises are located. It was shown that this territory is subject to aerotechnogenic pollution by a large set of chemical elements, but because of their low background content in mined iron ore and natural variation of soil composition, it is difficult to identify the technogenic impact using gross analysis. The determination of chemical elements associated with iron in Tamm extract in combination with chemical composition of road dust, is the most informative way to detect anthropogenic impact on territory, influenced by ferrous metallurgy enterprises.

Herbarium named after I.V. Novopokrovsky (RV): 100 years of the herbarium collection of K.M. Zalessky Demina Olga Nikolaevna1, Rogal Lyudmila Leonidovna2 1Karachaevo-Circassian State University named after U.D. Aliyeva, Russia, 369200, ul. Lenin, KChGU. E-mail: ondemina@yandex.ru 2 Southern Federal University, Russia, 344006, Rostov-on-Don, Botanical Descent, 7. SFU   Abstract:  The work reviews the herbarium collection of K.M. Zalessky, which has been stored for 100 years in herbarium named after I.V. Novopokrovsky Department of Botany of SFedU (RV). This is about 1 thousand of the most valuable rare specimens. At the beginning of the last century, he collected materials for the knowledge of the vegetation of the Lower Don region. These works, representing an inexhaustible source of botanical knowledge about the vegetation cover of the region, were systematically studied the vegetation cover of the Lower Don basin. The scientists for the first time characterized the types of Don steppes and on the basis of the herbarium, a flora outline was compiled, comprising 328 species of plants indicating their habitats and locations. Some of the places of herbarium fees given in this paper do not already exist or they were found outside the Rostov region: the habitat of Astragalus sulcatus collected by K.M. Zalessky on the meadow on May 31, 2017, in the vicinity of the village of Esaulovskaya, which belonged to the Second Don district (now the Volgograd region), is now flooded with the waters of the Tsimlyansk reservoir; habitats Asplenium septentrionale - the species was found by the scientist on June 5, 2017 in the crevices of the Royal rocks, on the territory of Ukraine (now it is a branch of the Lugansk nature reserve). Therefore, the herbarium collection from the southwestern and southern parts of the former Don Military Region serves as an invaluable historical evidence of the natural past of the Lower Don basin. Currently, the collection of K.M. Zalessky is used both for the compilation of fundamental floristic reports and for constructing various hypotheses on the dynamics of the Don flora and vegetation. These materials are the basis for studying the biological diversity of the Don region.  

Modern problems of natural and technogenic pollution of the environment (review) One of global problems of the present is pollution of the land area and water ecosystems by harmful ingredients. Scales of ecological consequences of environmental pollution steadily grow and consequences can be catastrophic. The number of natural and technogenic catastrophes has grown for the last 100 years by 20 times. Glaciers are intensively thaw in the Arctic and Antarctic . For the last 50 years temperature in the southwest of Antarctic has grown by 2,5 °C. Among natural sources of pollution the leading place is taken by volcanoes (520 acting from 1300), 250 thousand people have died from a tsunami in the Indian Ocean in 2004, because of accident on the NPP in Fukushima (Japan) in 2011 15,5 thousand people have died. Annually in the world there are more than 200 thousand fires, in Russia their quantity has grown from 2000 to 2009 from 9 to 22%. The huge contribution in environmental pollution is brought by the enterprises, motor transport, agriculture (mineral fertilizers, pesticides, etc.). In 31 countries 192 NPPs (more than 450 power units) work, 80-90% of waste of nuclear fuel production are stored locally around nuclear power plants, and then taken out on burial in the mines located in Russia in the Urals and in the USA – in 180 km from Las Vegas. The special danger is caused by nuclear weapon and nuclear waste, space debris, solid and liquid household waste. In the Baltic Sea over 300 thousand tons of the chemical warfare agents (CWA) are buried, in the Kara Sea 17 thousand containers with radioactive waste, 16 nuclear reactors, 5 atomic submarines, etc. are based. Plastic waste has polluted the rivers, the seas and oceans. From 1901 to 2007 in the world there were 1125 largest industrial accidents, more than 6 billion tons of mineral fertilizers, 8,3 billion tons of plastic are made and applied. Studying of diverse influence of anthropogenic factors on the environment is one of the most important current issues. An ultimate goal of such research – protection and improvement of the habitat of the person.  

Methodical principles for determining the bulk density of chernozem Morozov Igor V., Vareldzhan Diana E., Borovikova Yana V., Kolesnikova Nadezhda A. Southern Federal University, Rostov-on-Don, Russia; migovad@sfedu.ru Abstract: Bulk density of soils is a fundamental physical value, wich is used in soil science to assess the relationship between solid, liquid and gaseous phases of the soil, to calculation of the total and differential porosity, stocks of substance, estimation of the degree of addition, and other agrophysical characteristic.The purpose of the research is designing of methodical principles for determining of the bulk density of chernozem. The feature of ordinary calcareous chernozem is the change in volume when moisture is varied, it was decisive when research object was choosing. Drilling and calculation methods were used to determine the soil density. Studies have shown that the dynamics of soil moisture is the reason of bulky changes in the soil, which is fixed by us in the form of parameters such as volume compaction and swelling volume. Also volume changes inevitably must be reflected in the change of the parameters of soil density. The dynamics of the bulk density when the soil moisture change is due to the phenomena of swelling and compaction exactly. At that the result of determination of soil bulk density will depend on the initial condition of soil: its moisture and, the occupied volume accordingly. The same soil can have different bulk density values - 1.2 g / cm3 and 1.8 g / cm3, respectively. These values correspond to two possible limiting status of soil as a physical body with a variable volume. We think that the available methods require a conceptual solution; when calculating the bulk density, it is proposed to take into account the dynamics of the volume of the soil, determining the interval «compaction limit of bulk density - swelling limit of bulk density».

About the formation of carbonate horizon of ordinary calcareous chernozems Morozov Igor V., Bezuglova Olga S., Minaeva Evgeniya N. Southern Federal University, Rostov-on-Don, Russia, migovad@sfedu.ru Investigations were carried out on ordinary calcareous chernozem, which is named as migrate-segregated chernozem according to the Soil Classification of Russia (2004). The genesis of calcareous horizons is significantly linked with long-term dynamics of carbonates' precipitation. According to our opinion, upper boundary and deepness of accumulation of calcareous concentrations are determined by pulsating nature of the annual sum of atmospheric precipitations and their distribution during long-term cycle. The bottom boundary of water infiltration for significant part of atmospheric precipitations during 33th year period of observations is genetically related with a part of soil profile where calcareous concentrations are formed. About 71 % of the annual sum of atmospheric precipitations is percolated to the depth from 80 to 159 cm as a result of water infiltration into soil profile. It is an evidence of the paleomorphic nature of soil horizon where water-soluble salts and gypsum are significantly accumulated at depth 210-250 cm, and the same time is a proof of the absence of link with modern chernozemic soil-forming process.

Sod soils with groundwater and surface moisture of the Republic of Belarus (general characteristics and distinctive featur Pirogovskaya Galina Vladimirovna Abstract. The article describes the sod  soils of groundwater and surface moisture in Belarus based on the catenary genetic research and the results of the study of their properties, including studies after long drying. Comparative data on their morphological characteristics, physical and chemical properties, and the content of the absolute total reserves of moisture, organic matter, clay fraction and physical clay in layers of soil 0-20 cm, 0-50 and 0-100 cm, the bulk composition of the clay fraction are presented. It is shown that in sod soils with groundwater moisture the degree of chemical differentiation is reduced with an increase in moisture level, ie, profiles of sod temporarily excessively wetted soil and soils with partial gley features are differentiated chemically significantly stronger than sod-gley soils. Conversely, in the swampy sod soil with surface moisture degree of chemical differentiation grows with an increase in the hydration, that is, the profile of sod-gley soils is differentiated significantly stronger than that of temporarily excessively wetted soils and soils with partial gley features. Drainage of  all waterlogged sod soils is accompanied by a decrease of humus content, a change in its qualitative composition, the latter is particularly noticeable in the soils with groundwater soil moisture. This is due to the fact that the drainage of the sod soil with groundwater soil moisture causes irreversible changes in the general direction of the soil-forming process - the development of podzol. When draining sod soils with surface moisture there is an enhanced lessivage, while the soils stay amenable to cultivation and are recommended for use in intensive crop rotations.

Changes of Organic Carbon Pools in the Southern Taiga and Forest-Steppe of European Russia during the Historical Period Chernova Olga Vladimirovna, Ryzhova Irina Mikhaylovna, Podvezennaya Marina Aleksandrovna Abstract: Regional estimates of changes of organic carbon pools for Kostroma oblast (southern taiga) and Kursk oblast (forest-steppe) during the historical period were discussed. Actual and potential carbon pools in the phytomass and the 100-cm soil layer were calculated on a single map-based, with due account for the classification position of particular soils, their texture,  the character and age structure of forest stands, and land use patterns were taken into account. It was shown that the modern total organic carbon pool of Kostroma oblast by almost 25% below its potential; for the Kursk oblast this difference more than 30%. Soil organic сarbon pool of Kostroma region hasn't changed, a phytomass сarbon pool decreased by 40% due to the active use of forest resources. The high degree of plowing in Kursk region and almost complete reduction of woody vegetation led to a significant reduction in carbon pools of phytomass (75%) and soil (by 23-27%).

Fireweed (Chamaenerion angustifolium (L.) Scop.) from the Rostov region in herbarium collections in Russia O.N. Demina, L.L. Rogal, M.A. Abacharaeva Abstract. The paper provides an overview of the accumulated data and a brief history of the use of the fireweed (Chamaenerion angustifolium) in connection with its assumed harvesting. in Rostov region it is considered to be a rare species, listed in the regional Red Book, but in the adjacent areas the fireweed has no legal protection status. The above said served as the  basis for the study of herbarium collections that are stored in the country's largest herbariums. The obtained data allow us to determine its location in the basin of the Lower Don (basin of the river Glubokaja) and undertake measures aimed at the  protection of C. angustifolium in the Rostov region.

The content and distribution of heavy metals in gray forest soil and the specificity of their receipt in plants Konarbaeva Galina A., Yakimenko Vladimir N. Institute of soil science and agrochemistry Siberian branch of the Russian Academy of Sciences, Novosibirsk, Russia; konarbaeva@issa.nsc.ru Content and distribution of heavy metals in grey forest soil and specificity of their intake by plants Summary: The content and distribution of copper, cobalt and zinc were studied in the system plant – soil of long-term trial established at grey forest soil in the forest steppe belt of Western Siberia. The mineral fertilizers (nitrogenous, phosphoric and potassic) which were yearly applied in the agrocenosis in the course of a quarter of century served as a permanent source of heavy metals (HM). The conducted studies showed that optimization on of mineral nutrition of plants not only ensured of full value productional process but also reduced the content of HM in soil and plants. More over, the conducted studies confirmed general regularity of limitation of HM entry into reproductive and storage organs (seeds, fruits, tubers) and their heightened accumulation in generative organs (leaves, stems). Long-term use of scientifically grounded doses of fertilizers did not lead to accumulation of HM in soil and plants in meaningful amounts as concerns of active sanitary and hygienic guidelines. At the same time, contemporary level of chemicalization of farming requires the monitoring of HM under study in order to reveal their excess and lack.

Yao Mu, Xinzhi Mu Fossil energy is the product of a series of complex chemical reactions inside the earth under high temperature and pressure that occur over a long period of geological time. The production of fossil energy requires a tremendous heat source. Although the majority of coal, oil and gas exist in sedimentary basins with rich geothermal resources, a “sea of oil” or “sea of gas” does not occur within the crust. Petroleum, natural gas, shale gas, etc. exist underground in a huge “capillary network” that consists of rock pores, cracks, caves, faults and sand. Cracks and faults may be entirely within the crust. Deposits of fossil energy only cover a small portion of the earth’s surface, and the maximum depth of human mining is only 5 kilometers. Petroleum, natural gas and shale gas seal these pores, cracks, faults and sand beds, effectively preventing excessive leakage of terrestrial heat flow. The enormous pressure formed by petroleum, natural gas and shale gas within the crust oppose the earth’s interior thermal pressure, achieving a dynamic balance. Once petroleum, natural gas and shale gas have been mined, the earth’s interior terrestrial heat flow follows the capillary network because of the loss of thermal insulation and heat-sealants and eventually reaches the surface, causing the crust underlying the surface to “fever” and triggering ecological and geological disasters. Huge amounts of extreme dispersed heat force the water vapor, CO2, CH4 and other gases from the crust into the atmosphere and oceans, which disrupts the atmospheric energy balance and causes climate change and meteorological disasters. With increasing sea temperatures, air humidity has also increased, which has produced the strongest recorded typhoons, hurricanes and tropical cyclones, as well as the strongest recorded local rainfall, snow, drought, winter and cold conditions. These conditions are expected to become more frequent, with the weather becoming more extreme and violent. Global climate will long-term warming if energy mining does not stop.

The follicle-stimulating hormone receptor gene (FSHR) polymorphisms and hormon levels in women undergoing assisted reproductive treatment This study was performed to investigate the association between FSH receptor (FSHR) gene polymorphism at position 680 and the number of dominant follicles, also the FSH and LH levels before controlled ovarian hyperstimulation and after it. One hundred patients from 24 to 42 who underwent IVF-ET procedures were included in this study. Three groups were formed: patients with normal ovary response, patients with ovary hyperstimulation and patients with poor ovary response. The FSHR polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism analysis. The FSHR genotype distribution in patients with normal ovary response was 45,3%  for AA, 39,6% for AG and  15,1% for GG. There was no difference among the three genotype groups. The basal levels of FSH and levels after controlled ovarian hyperstimulation were significantly higher in patients with poor ovary response. LH levels after controlled ovarian hyperstimulation were significantly lower in patients with normal ovary response. The basal levels of AMH were significantly higher in patients with ovary hyperstimulation.

Finding a new species of snowdrop (Galanthus platyphyllus Traub et Moldenke) for the flora of Karachay-Cherkessia The endemic Caucasian snowdrop flat-leaved (Galanthus platyphyllus Traub et Moldenke, 1947) is a rare species listed in the Red Book of the Russian Federation and a number of regional ones. It has a limited area, part of which is located on the territory of Russia. In the Red Book of the Krasnodar Territory, the species is listed with a category and status as "Vulnerable" - 2, a locally encountered Transcaucasian endemic species with a shrinking population, where it is threatened with final destruction; is also included in the Red Book of the Republic of North Ossetia-Alania, where the state of its population due to the inaccessibility of habitats is not of particular concern. G. platyphyllus is included in the Conventionon International Trade in Endangered Species of Wild Fauna and Flora (CITES, Appendix II) (2006). On the territory of the KCR, until now, it was reliably known of the growth of only the alpine snowdrop – G. alpinus Sosn., collected in the vicinities of the village of Asiatsky, in a moist beech forest, on the slope of the northwestern exposition in the valley of the river B. Laba. The location of G. platyphyllus was previously unknown and is given for the first time. The location of G. platyphyllus was found in a moist forest, in the valley of the river B. Laba, on the right bank, 6 km to the south from the village of Asiatsky settlement, 902 m above sea level. Sea, April 5, 2017. Flowering was recorded in early April.

170 years since the birth of V.V. Dokuchaev Bezuglova Olga Stepanovna Abstract: March 1, 2016 marks 170 years since the birth of  V.V. Dokuchaev – an outstanding scientist, naturalist, founder of soil science. His views, theoretical and practical research influenced the development of a number of related disciplines, as well as the later appearance of such sciences as the doctrine of the biosphere and biogeochemistry.   Dokuchaev's ideas to restore the fertility of chernozem  steppes, which were implemented, have slowered the rapid degradation of the soil, but the situation remains difficult. In this regard, one of the urgent tasks of modern soil science is to increase public awareness of the importance of soils for food security and the implementation of essential ecosystem functions.

Special features of highly technological processing of the tomatoes  In the food branches of the industry of many countries the tomatoes are considered as the most popular culture because of the valuable nourishing and dietetic qualities, the wide variety of types, high responsiveness to the methods of cultivation used. However, the state of technology and equipment for processing of tomato raw material existing at present requires further development and improvement.  Canning industry is the branch forming the budget of the republic of Daghestan. To 30  % the financial means of republic it comes from that processing, including from canning industry. However, according to the quality indicators and using the methods of packing the canning production, manufactured in the republic thus far cannot compete with the analogous production on the international market. In many respects the low competitive ability of domestic tomato products determines the irrational relationship between price and quality of the manufactured articles. To increase the quality of canning output and to reduce its prime cost is possible due to the thorough selection of the types of tomatoes and use of highly technological production processes. In the scientific arsenal of the technologists of  Daghestan State Technical University and Kuban State University of Technology has already been located high technologies and pour on the mechanisms of action on the qualitative composition of the tomato raw material of multi-frequency electromagnetic and ultrasonic. By the large potential of highly technological working of raw material possess the methods of the preparative separation of the components of raw material the liquified and compressed gases. New technological methods make it possible to produce production without the preservatives, the fillers, the chemical, undesirable aromatic substances and other additives. In this work we propose effective means of the solution of this problem in the use of physical, physical chemistry and chemical methods of action on the tomato raw material, semifinished products, auxiliary materials and finished production. They include the electromagnetic field of low and superhigh frequencies, ultrasound, the SO2- working, utilized in other branches industries.

30 years' Changes of Probabilistic and Information Characteristics of the Humus Content in Southern Chernozems in Western Siberia The analysis of transformation of the probabilistic-statistical distributions (PSD) of the humus content in southern chernozems at the studied territory in the whole, situated on the Priirtyshsky uval for the 30-year period revealed existence of the tendency to decrease in the humus content in the top layer and its increase in underlying layers of soil. Transformation of PSD of the humus content is followed by very essential reduction of statistical entropy up to 60% of initial value that speaks about essential change of a condition of chernozems in spite of the fact that taxonomically soils don't change. The analysis of information divergence showed that the revealed tendencies in a sandy loam version are expressed more strongly, than in the loamy soils. And the greatest transformation of PSD of the humus content for the studied period happened in a layer 30-50 cm due to increasing of the low boundary of the interval of variation. The revealed transformations of PSD are interpreted from the point of view of interaction of soilforming, climatic and landscape and exogenous processes.

Application of the European soil standards in the territory of Azerbaijan At present the integration to the European and international structures goes on in many directions, including scientific. Against a background of globalization it is fundamentally important to form an adequate soil-information space which would ensure progressive international cooperation in the field of soil science. As is known, the new digital soil database of Mediterranean and Caucasus Countries’ territory in the format of the soil geographical information system of the European Union (EU) is being prepared within the program for the Extension of the European Soil Database (ESDB). These researches intend to create the Soil Geographical Database of Eurasia at scale 1 : 1, 000, 000 as a part of the European Soil Information System (EUSIS). The current stage of the Azerbaijan soil resources inventory on supranational level is closely linked with the processes of adaptation of the country to the conditions of new geopolitical realities. It is of fundamental importance to preserve and develop the national scientific and practical traditions and their harmonious integration with the EU soil inventory. Taking into consideration the urgency of the problem, we have made researches in order to create the digital data base of the soils of the Republic of Azerbaijan. The digital soil map of Azerbaijan has been prepared in a scale of 1:1000000 using modern geoinformation technologies and taking into account the ESDB requirements. During the analysis of soil database of Azerbaijan, some difficulties that impede the integration process to the ESDB were revealed. Generally, the work that has been done brought to a conclusion that the knowledge available on soils of Azerbaijan makes the integration to the EU soil-geographic data base possible.

Petrol Products in Soil. Terminology and Definition of the Problem Okolelova A. A., Bezuglova O. S., Kasterina N. G. The term «oil products» can be defined both in technical and analytical ways. From a technical point of view, oil products (OP) are raw oils after the initial processing at the excavation facilities. Methods and definitions of water diagnostic limit the term «oil products» to soluble hydrocarbons. We propose to replace the term «organic carbon of oil toxicants» with «organic carbon of antropogenic origin». We furthermore suggest considering oil compounds as «organic pollutants» or xenobiotics. In the research it is suggested to calculate the oil content of the soils by the quantity of anthropogenic carbon. Additionally, the oil products accumulation factor (Kn) is suggested to use for an impartial assessment of the oil content in soils including the quality of their compounds.

About the Relative Amount of the Living Matter in the Various Stages of the Evolution of the Biosphere Zakrutkin V. E. The article has shown that early periods of the Biosphere’s evolution had been the most productive in the development of all parameters in the life of the autotrophic organisms. Later on, the CO2 content — the fundamental agent of the photosynthesis — has permanently declined, the climatic conditions (the thermal regime and humidity) have grown worse, the mineral nutrition has decreases. In general, all this has become the reason of cumulative photosynthesis, the productivity of the Biosphere and the total mass of living organisms. The real substantiation of the presented hypothesis has become the results in the estimation of the rate of the organic matter accumulation at the various stages of the geological history.

Norms for Arsenic’s Contamination of Soil Bezuglova O. S., Okolelova A. A. In our research we identify inaccuracy in assessment of low-degree arsenic’s contamination based on two background values to MPC, because the MPC is calculated in terms of exceeding background values higher on 2 mg/kg. We evaluate the low-degree arsenic’s contamination of soils as the difference between background values and MPC. Another informative assessment of arsenic’s accumulation in soils includes analysis of ratio of its concentration to the regional background value. In case if the regional background value is unknown, the assessment employs the ratio of arsenic’s concentration to Clark (CC). However, CC doesn’t have the classification scale. That fact reduces its benefits as useful assessment tool of soil contamination’s degree. In our article we devise CC’s classification scale that works for the assessment purposes.

Sunflower Chlorophyll Mutations Induced by N-Nitrosomethylurea and Character of Its Inheritance I. Variegated Mutants Usatov A.V. , Kolokolova N.S., Rogkova O.K., Usatova O.A., Chesnokova N.A., Fedorova M.A., Plotnikov v. G. Variegated mutants of the sunflower chlorophyll mutant collection of Southern federal university were studied. Its uniqueness consists in the fact that it was worked out on the base of one inbred line. Secondly, only one mutagen (N-nitrosomethylurea) was used for mutation inductions. Variegated mutants are characterized by leaves having white, yellow and yellow-green sectors of the various sizes and forms. Chlorophyll deficient sectors may be caused by some reasons in green plants. However, long-term researches of induced variegated mutants showed that they met the classic criteria of plastid inheritance. They are characterized by permanent somatic segregation, one-parental maternal inheritance of mutant character, defects of plastid structure and functions, presence of heteroplastid cells on the borderline between normal and mutant tissues.

Mn content and distribution in southern chernozem during cultivation of various crops. The results of investigations of manganese content and distribution in Haplic Chernozem agrocenoses of the central irrigated zone of Rostov region are given.  Soil samples were taken by genetic horizons from 5 full-profile transects: 2 – under winter wheat; 2 – under vine plants; 1 – under clean fallow. Acetate-ammonium buffer solution was used to determine mobile Mn compounds in soil, followed by application of atomic absorption spectrometry. The total content of the element was determined by X-ray fluorescence analysis on the device "Spectroscan MAKS-GV". It was found that the content of manganese, both gross and mobile, in the Haplic Chernozem corresponds to the background level and does not exceed permissible concentrations. The low mobility of biomicroelement (1,6 -5,0 % of total) is a regional feature of soil. Biological features of cultivated crops determine the content of mobile compounds of manganese. The general regularity in distribution of gross and mobile compounds of Mn in Haplic Chernozem, caused by biogenic accumulation in the upper part of humus horizon, has been revealed. The peculiarities of intraprofile differentiation of gross and mobile manganese by genetic horizons of Haplic Chernozem have been established: for gross manganese a smooth decrease down the profile, for its mobile compounds – accumulation in the upper humus horizons, then a sharp decrease with an increasing  the alkalinity of the soil solution.

Anthropogenic Factors Determining the Nature of the Absheron Industrial Region Urbanized Territory – Sumgait – Baku Cities Eng. Anthropogenic Factors Determining the Nature of the Absheron Industrial Region Urbanized Territory – Sumgait – Baku Cities Bagirova Chinara Z. Institute of Microbiology of the Azerbaijan National Academy of Sciences, Baku Abstract: The article considers anthropogenic and technogenic factors that affect the ecological state of the landscapes of the Absheron industrial region and the components of the ecosystems of Sumgait and Baku-soil, atmosphere, and water. In the highly urbanized territory of the Absheron industrial region in the areas of the Sumgait-Baku cities, the main sources of pollution are emissions from petrochemical, chemical, machine-building and other industries, oil production in the territories adjacent to the city, and motor transport. A systematic analysis of the state of the territory of the Absheron industrial region showed that the low level of assimilation capacity of the environment of the studied region is primarily determined by a high degree of urbanization, arid climate, low ecosystem weight and low natural biodiversity, which determines a high level of sensitivity to pollution and low oxygen reproductive capacity – only 0.8 million tons / year, associated with weak vegetation cover (covered with natural ephemeral vegetation only in spring and autumn), an increase in the ground water level, low bioclimatic potential, unfavorable water-thermal regime, lack of surface water, runoff, the presence of highly mineralized, polluted reservoirs, the characteristic unstable relationship between individual components in landscapes and the lack of mutual compensation between them.

Fractional composition of mineral phosphates in Haplic Chernozem with different cultivation methods Fractional composition of mineral phosphates in Haplic Chernozem with different cultivation methods Kuchmenko E.V.1, Biryukova O.A.1, Kamenev R.A.2 Medvedeva A.M. 1 1 Southern Federal University, Rostov-on-Don, Russia 2 Don Zonal Research Institute of Agriculture, Rassvet, Russia;   Abstract: The fractional composition of mineral phosphates in the soil depends on its genetic features and the impact of various factors on the soil, including anthropogenic factors. The purpose of this research is to study the fractional composition of mineral phosphates in Haplic Chernozem under different tillage techniques. The research was carried out as a field experiment on the territory of CJSC Novobatayskaya of Kagalnitskiy district, Rostov region. The scheme of experiment consists from 1) ploughing (25-27 cm), 2) discing (10-12 cm), 3) chiseling (no-tillage to a depth of 25-27 cm). Experimental crop is winter wheat (Triticum aestivum). The soil is Haplic Chernozem carbonate thick clayey on loess loam. Soil samples were taken before sowing and in the phase of winter wheat emergence at layers: 0-20, 20-40, 40-60, 60-80, 80-100 cm. Fractional composition of mineral phosphates in the soil was determined by the Chang and Jackson method modified by Ginzburg-Lebedeva; total phosphorus was determined by X-ray fluorescence analysis. It was found that the Haplic Chernozem is characterized by a rather high potential of phosphorus supply to plants nutrition. Before sowing winter wheat, the content of total P2O5 varies from 0.17 to 0.19 %. Mineral phosphates in the top layer of Haplic Chernozem carbonate account for 42.0-43.0 % of total phosphorus during chiseling and discing, and 32.0 % of total phosphorus during moldboard ploughing. During the emergence phase, their amount decreased slightly due to intensive use by plants. The main share of mineral phosphates in Haplic Chernozem, regardless of the cultivation method, is represented by high-basic calcium phosphates (Ca-PIII), which is due to genetic features of the soil. The solubility of calcium phosphates decreases with depth. No-tillage methods (discing and chiseling) increase the content and availability of mineral phosphates to plants in Haplic Chernozem compared with the ploughing. However, the observed effect according to the results of the first year of research is not significant, indicating the need for multi-year studies.

Drought resistance of species of the genus Acer L. from the collection of the Botanical Garden of the Southern Federal University in the extreme drought year 2020 Drought resistance of species of the genus Acer L. from the collection of the Botanical Garden of the Southern Federal University in the extreme drought year 2020 Fedorinova Ol'ga I., Kozlovskij Boris L., Kuropjatnikov Mihail V. Southern Federal University, Rostov-on-Don, Russia   Abstract: According to the value of the hydrothermal index (HTI) G. T. Selyaninova Rostov-on-Don is located in the arid area (0,7 – 0,8). Drought usually begins in mid, or in late summer. In the steppe zone for introduction into the culture of woody plants monitoring of development during drought is important. This gives the most complete characterization of their properties and decorative longevity. From the complex of ecological and biological properties of woody introduced species (winter hardiness, drought resistance, resistance to pests and diseases, seed reproduction) drought resistance is considered an essential property. The aim of the research was to assess the severity of drought in typical and atypical years using HTI; to give a comparative assessment of the drought resistance of woody plants in the collection of the Botanical Garden of the Southern Federal University using the example of the genus Acer L. According to the value HTI (<0,6), drought in 2020 was extreme. The complete absence of precipitation was observed for more than 2,5 months from August to mid-October. Thirteen maples showed average resistance to drought (grading 3). Two species were found to be weakly drought-resistant. The results of assessing the drought resistance of species in the extreme drought in 2020 showed that 15 maples are the most drought resistance and decorative longevity (30-50 years): Acer campestre, A. monspessulanum, A. monspessulanum subsp. ibericum, A. opalus, A. pentapomicum, A. platanoides, A. platanoides ‘Schwedleri’, A. platanoides ‘Globosum’, A. pseudoplatanus, A. pseudoplatanus ‘Purpureum’, A. saccharinum, A. tataricum, A. tataricum subsp. aidszuense, A. tataricum subsp ginnala, A. truncatum.

The relevance of this area of research is dictated by the high prevalence of obesity not only in the adult population, but also in children. The aim of this work is to study the potential relationship between the polymorphisms of the PON1 Q192R, LIPC -250G> A, LPL Ser447Ter, FTO A23525T genes and the risk of obesity, atherosclerosis, and diabetes in children and adolescents in Europe and the European part of Russia by means of meta-analysis. Methods. A systematic review and meta-analysis of the results of 9 case-control studies meeting the selected criteria has been carried out. The meta-analysis included 3603 people, divided into groups: children and adolescents with obesity or overweight — 1,877 people and children and adolescents who made up the control group, with normal weight or underweight — 1,726 people. Results. For rs9939609 of the FTO gene, a 2-fold increased risk of obesity for homozygotes for allele A was revealed (p <0.0001). Statistically significant differences for children and adolescents with obesity and normal weight were found for the dominant and recessive inheritance patterns (p <0.0001). Conclusions. Analysis of genotype frequencies in girls revealed statistically significant differences for homozygotes for allele A (p = 0.00268). For the recessive inheritance model, significant differences were found in boys and girls. The odds ratios for the A23525A genotype for girls and boys with obesity and normal weight were 1.74 (p = 0.0022) and 1.65 (p = 0.0094), respectively.

RARE PLANT SPECIES IN THE TERRITORIES OF PROTECTED LANDSCAPES OF THE ROSTOV REGION RARE PLANT SPECIES IN THE TERRITORIES OF PROTECTED LANDSCAPES OF THE ROSTOV REGION Fedyaeva Valentina Vasilievna, Shmaraeva Antonina Nikolaevna, Shishlova Zhanna Nikolaevna, Kuzmenko Inna Petrovna Southern Federal University, Rostov-on-Don, Russia; vfedyaeva@gmail.com Abstract: Rostov Region is located in the steppe zone, which is the most transformed type of zonal landscape in Northern Eurasia. The problem of preserving biological diversity in the Rostov region is being solved by developing a network of specially protected natural areas (SPNA). Currently, there are 84 specially protected natural areas in the Rostov region with a total area of 233,49 thousand hectares, which is 2,32 % of the region's territory. The biological diversity of plants and fungi was determined in protected areas of the category «protected landscapes», including species included in the Red List of the Rostov region. Protected landscapes are natural complexes with an area of more than 100 hectares of both natural and artificial origin, representing environmental, educational, aesthetic, and scientific value. Protected landscapes are available in 17 out of 43 administrative districts of the Rostov region. The total area of protected landscapes is 21,51 thousand hectares. This amounts to 9,2 % of the total area of SPNA operating in the Rostov region. At least 1263 species of plants and rare fungi grow on the territories of protected landscapes, including 139 species listed in the Red List of the Rostov Region (50,9 % of the total number of «Red List» objects of the region), including 31 species listed in the Red List of the Russian Federation (60,8 % of the total number of «Red List» federal objects growing on the territory of the Rostov region). The concentration on a relatively small area of protected landscapes of a significant number of plants and fungi listed in the Red Lists of the Rostov Region and the Russian Federation indicates their high conservation value.

Mapping of anthropogenic landscapes of the taiga belt in the south of Western Siberia in order to determine the ecological and soil status Mapping of anthropogenic landscapes of the taiga belt in the south of Western Siberia in order to determine the ecological and soil status Dvurechenskiy Vadim G. Novosibirsk State University of Architecture and Civil Engineering (Sibstrin); Russia; E-mail: dvu-vadim@mail.ru Dvurechenskaya Valeria V. Moscow State University of Technology and Management; Russia Abstract: The aim of the work was to map the anthropogenic landscape created in the mountain taiga in the south of Western Siberia as a result of mining operations in coal mining, to determine its ecological and soil status.  The study was carried out by laying 10 m long transects, to fix the lengths of the section of one or another anthropogenic habitat crossed by the transect with the corresponding outline. The article reflects the features of the formation of soil cover in anthropogenic landscapes, which genetically sharply differ from the soil cover of natural landscapes. In disturbed ecosystems, as a result of self-overgrowing, various types of embryozems are formed; in natural ecosystems, deep podzolic soddy soils are determined in natural ecosystems under the black taiga, and brown taiga soils under secondary forests. Mapping showed that during natural self-restoration in anthropogenic landscapes, a mosaic specific soil cover is formed, which includes embryozems: initial, organo-accumulative, sod and humus-accumulative soil cover. The ecological and soil status of the flattened areas under herbaceous vegetation (plots 1 and 3) is good and satisfactory, since after 50 years from the moment of the initial phase of anthropogenesis, embryozems of late evolutionary stages – sod and humus-accumulative, predominate in the soil cover. The ecological and soil status of slope surfaces (plot 2) and areas under trees (plot 4) is unsatisfactory, but it has some development prospects. The ecological and soil status of the entire landscape can be considered satisfactory. Trends in the direction of soil development have been determined. In the near future, the soil cover is expected to form: on graded areas – humus-accumulative embryozems, under trees – various subtypes of organo-accumulative embryozems (burozem-like, pseudopodzolized). In the distant future it is predicted: in flat areas under taiga forbs – rough-humus mountain soils, under tree and shrub vegetation – brown mountain taiga soils.

Eng. Genetic characteristics of the SARS-CoV-2 Novikova Irina Alekseevna1 1 Southern Federal University, Rostov-on-Don, Russia Annotation: This review describes the genetic characteristics of the virus, the main ways to diagnose COVID-19 infection. The SARS-CoV-2 virus is a single-stranded RNA molecule, the length of the virus genome varies from 29.8 kbp. up to 29.9 kb Comparative genomic analysis showed that SARS-CoV-2 belongs to the group of beta-coronaviruses and is very close to SARS-CoV. Initial comparative genomic analysis showed that SARS-CoV-2 is almost 79% identical to SARS-CoV and 50% identical to the MERS-CoV virus. Based on homologous modeling studies, SARS-CoV-2 has been shown to be 96.2% homologous to BatCoV RaTG13, a bat coronavirus of the genus Rhinolophus affinis. Studies to establish the origin of SARS-CoV-2 have shown that random mutation and recombination are two main sources of the genetic diversity of this virus. Recently published works show that the frequency of SARS-CoV-2 mutations is approximately the same as in the SARS-CoV genome (0.80-2.38 × 10-3 nucleotide substitutions per site per year). The most common types of mutations in the SARS-CoV-2 genome are synonymous and missense mutations. Mutations of other types were also found in the SARS-CoV-2 genome: nonsense mutations, insertions, deletions, mutations of non-coding DNA. At least seven genetically independent clones have been found that have acquired a mutation at one specific site Q677H or Q677P of the Spike virus spike protein gene.

Decomposition of leaf litter in case of zinc contamination of Calcic Chernozem and the effect of the humic solution BIO-Don on this process Eng. Decomposition of leaf litter in case of zinc contamination of Calcic Chernozem and the effect of the humic solution BIO-Don on this process Bezuglova O.S., Gorbov S.N., Korban V.A., Mikhailova E.A., Pirgulian E.A., Skripnikov P.N., Tagiverdiev S.S., Fedorets D.G., Sherstnev A.K. Southern Federal University, Rostov-on-Don, Russia Abstract: In a model experiment, the decomposition of white poplar leaf litter in the humus-accumulative horizon of Calcic Chernozem was studied. Experimental choice included artificial contamination with a zinc sulfate solution, as well as watering with water with a humic solution. The duration of the experiment is 1 month. After this period, soil and decaying litter were taken. The total content of zinc in the soil was determined by X-ray fluorescence method and the amount of mobile zinc compounds in the acetate-ammonia extract was determined using atomic absorption spectroscopy, as well as the state of structural units by dry and wet sieving. In an aqueous extract from decaying leaf litter, the content of carbon and nitrogen was determined. It was found that watering with water containing a humic solution promotes the acceleration of the decomposition and humification of leaf litter: the concentration of carbon in the extract from the decomposing litter increases, as well as the value of the chromaticity coefficient. The addition of zinc sulfate with irrigation water led to a high degree of soil degradation, and this reduced the rate of decomposition of plant residues. The combined addition of zinc sulfate and the humic solution accelerates the decomposition of plant litter, practically eliminating the negative effect of zinc pollution on this process. When humic fertilization is applied to the soil, there is a significant increase in the percentage of agronomically valuable aggregates and a convincing increase in the value of the structural coefficient. Zinc contamination practically does not affect the results of dry sieving, but it sharply increases the water resistance of the aggregates to the destructive action of water.

Genetic aspects of fetal growth restriction. Eng. Genetic aspects of fetal growth restriction. Dema Alset Southern Federal University, Rostov-on-Don, Russia Abstract: Fetal growth restriction (FGR) is a multifactorial pregnancy-related syndrome that causes serious and dangerous short-term and long-term outcomes due to inappropriate intrauterine development of fetal organs. According to latest statistics, FGR frequency in Russian Federation is 5 % to 17,5 % among full-term infants and even more among premature newborns. This incidence is still growing due to the absence of united diagnostic or therapeutic protocols. Moreover, FGR etiology is not fully understood though it has been linked to many mechanisms and signaling pathways. Genetic factors have been found to play an important role in FGR, but the exact effect of them are still unknown. Currently, many studies are focused on finding the most reliable genetic marker for FGR since it could be helpful for prenatal prognosis and thus for improving fetal growth during pregnancy. In this article, recent findings about FGR were analyzed with an emphasis on the role of genetic factors in the formation of this syndrome and many genetic candidates studied in various researches as associated with it. Chromosomal abnormalities were found to be associated with early FGR while genetic mutations and polymorphisms of many genes were more abundant in late cases. Candidates genes include growth hormone and Insulin-like growth factors genes, coagulation-related genes, cytokines and others. Moreover, recent studies have found association of non-coding genes and epigenetics with FGR mechanisms. Further studies are required to figure out the effect of each genetic factor and thus reach the critical prenatal genetic markers of FGR.

Characteristic of microbial strains resistant to white phosphorus Abstract White phosphorus is one of the most dangerous environmental pollutants. In our works, cultures of microorganisms growing in media with a content of white phosphorus up to 1 % were obtained for the first time. These cultures are unique, and they are demonstrate first ever example of the inclusion of white phosphorus in the biospheric circulation of the phosphorus element. The morphological, partly biochemical and taxonomic descriptions of cultures of microorganisms that carry out the biodegradation of white phosphorus are performed. This work is important because a unique set of characters is a characteristic of the strain. The fact of the existence of a new strain of a microorganism is established only from the moment of its accurate description. s a result of the studies, the species affiliation of the studied microorganisms was established. It was confirmed by amplification of fragments of the 16S rRNA genes (in the case of streptomycetes prokaryotes) and 18S rRNA (in the case of fungi eukaryotes), carried out by the standard PCR method, using data from the international NCBI database. New strains of Aspergillus niger and Streptomyces sampsonii species have been identified. The research results show that the biodegradation of white phosphorus can be carried out by microorganisms from various taxonomic groups. Currently, the described strains are deposited in the All-Russian collection of microorganisms and may be subject to patenting.

Ивановского Южного федерального университета, Россия  Аннотация: Усилия по сохранению естественной среды обитания и среды обитания человека посредством сохранения окружающей среды, направленные на изменение их показателей, всегда предпринимались на протяжении многих лет. Целью данного исследования является количественная оценка изменений показателей экосистемы в районе Кон Куонг, провинция Нгеан, Вьетнам, с 2000 по 2015 гг. В этой области исследований также есть национальный парк Пу Мат, где богато биоразнообразие среды обитания, видов, генов, а также экосистем. В этой статье семь индикаторов измеряются с помощью программного обеспечения ГИС и Fragstats, в том числе индекс разнообразия Шеннона (SHDI), индекс разнообразия Симпсона (SIDI), количество патчей (NP), плотность патчей (PD), процент подобных смежностей (PLADJ), индекс перемежения и сопоставления (IJI) и плотность края (ED). Значение для каждого индикатора будет присвоено для каждого наблюдения, чтобы отразить характер экосистемы. Они будут сравниваться друг с другом и учитываться изменения в экосистемах лесных, сельскохозяйственных, искусственных и других. Метод тематических наложений и переходных матриц также использовался для точной идентификации изменений экосистемы, произошедших за рассматриваемый период. В результате было получено подробное объяснение и картирование динамики экосистемы. Эта работа может быть воспроизведена и превратилась в методологическую фазу, чтобы показать индикацию экосистемы, потому что она добавляет эталонное значение для изучения различий в характеристиках экосистемы. Результаты показывают, что различие в окружающей среде в основном связано с уменьшением естественности и увеличением сложности сельскохозяйственных экосистем и роста городов.

Styding morphometrical indicators of palisad aparatus Quercus robur L. и Quercus rubra L. in an urbanized environment (on the example of Kaliningrad city). Petrova Natalia G1, Mandrik Vladlena A1  1Immanuel Kant Baltic Federal University, Institute of Living Systems, Universitetskaya St., 2, Kaliningrad, 236040, Russian Federation. E-mail: petrova_sov@mail.ru Abstract:  In recent time had increased the extremely negative human influence on green spaces in the urban environment.  Impact of anthropogenic pollution leads to changes in the appearance of plants and morphometric parameters. The most sensitive and informative organ of plants is a leaf, it reflects the negative impact of the environment. The article considers the influence of the urban environment (areas with high traffic load) on the change in the morphological parameters of the assimilation apparatus in two types of plants of the genus Quercus L., they are often used in landscaping of Kaliningrad city. The purpose of the research is – studying some morphometric parameters of the assimilation apparatus in two types of plants as the genus Quercus: robur  L. and rubra L. in conditions of urbanized environment (on the example of Kaliningrad city). Quercus robur L. local species, Q. rubra L. Invasive plant, introduced to culture (East Prussia) in the late 19th century. In the research were used different methods such as: general scientific methods (observation, description, measurement, analysis, generalization) and special methods of bioecological research (anatomical and morphological, statistical). The vital state of plants has been studied, fluctuating asymmetry of leaves, morphometric parametres of the assimilation apparatus (the value of annual growth, the size of the leaf blade, the number of stomatous per unit area and parameters of the stomatous apparatus ). Some of morphometric parameters of the assimilation apparatus Q. robur L. и Q. rubra L. in the conditions of urban environment, indicate an increase in xeromorphism, others point to its weaking. Both the increase and decrease in xeromorphism indicators in these species should be considered as adaptive responses of plants to negative factors of environmental pollution.

Re-inventory of the flora of the Starikovsky site of the "Rostovsky" reserve The studies were carried out within the framework of a project to determine the value of the Starikovsky site of the State Natural Biosphere Reserve "Rostovsky" and a possible change in the composition of the vegetation cover, in connection with which a re-inventory of its flora was required. Under the conditions of a strict reserve regime and intensified drought, global changes in the floristic composition took place - some species disappeared and others appeared. Some of the views have been redefined. New species have also been identified, including 49 for the territory of the Starikovsky site. As a result of the research carried out, a re-inventory of the flora of the Starikovsky site was carried out and a new annotated list was compiled, including 312 species of higher vascular plants. The main attention was paid to the species of vascular plants listed in the Red Data Books of the Russian Federation and the Rostov Region, of which there are 14: 7 species of wild higher vascular plants included in the Red Data Book of the Russian Federation were registered: Stipa pulcherrima C. Koch, S. zalesskii Wilenskiy,  Tulipa schrenkii Regel, Iris pumila L., Calophaca wolgarica (L.fil.) Fisch. ex DC., Eriosynaphe longifolia (Fisch. ex Spreng.) DC. and Bellevalia sarmatica (Georgi) Woronow; 7 more species listed only in the Red Data Book of the Rostov Region: Stipa sareptana A.Beck., S. ucrainica P.Smirn., Psathyrostachys juncea (Fisch.) Nevski, Tulipa biflora Pall., Crambe tataria Sebeok, Astragalus physodes L., and also A. calycinus Bieb. – var. multiflorus Novopokr., which differs from the Caucasian species in its reddish calyx at the top, longer peduncles and multi-flowered inflorescences with smaller flowers. It should also be noted that an abundant growth of lichens was noted in the Starikovsky site, including Cladonia convoluta (Lam.) Cout., Neofuscelia pulla (Ach.) Essl. and Cetraria steppae (Savicz) Kärnefelt, listed in the Red Data Book of the region.

Biological characteristics of the carp Cyprinus carpio Linnaeus, 1758 in the South-Eastern part of the Taganrog Bay and the Don. Biological characteristics of the carp Cyprinus carpio Linnaeus, 1758 in the South-Eastern part of the Taganrog Bay and the Don. Guskov Gleb E.1, Guskova Olga S.2 1 Federal State Budgetary Institution of Science "Federal Research Centre The Southern Scientific Centre of the Russian Academy of The Sciences" (SSC RAS), Rostov-on-don, Russia; gleb_guskov@mail.ru 2 The Azov-Black Sea Branch of Russian Federal “Research Institute of Fisheries and Oceanography” (“AzNIIRKH”). Rostov-on-don, Russia.   Annotation: Over the past 50-70 years, significant changes in the hydrological and meteorological conditions have occurred in the Azov-Don basin. As a result of anthropogenic impact on the river flow of the river As well as due to climate change, the natural spawning grounds of a number of fish species, including valuable commercial ones, have significantly decreased. Intensive fishing in the past years has led to a significant reduction in the ichthyofauna of this basin. The object of our study is the wild carp Cyprinus carpio Linnaeus, 1758. This is one of the most valuable commercial fish species in the Don river basin, which requires control over the state and distribution of its population. Taxon was quite common for the f the Don basin. In the mid-90's, about 3-5 tons of wild carp were caught annually in the course of fishing in the Don and areas. However, over the past decade, the number of wild carp has declined sharply. This paper analyzes the General state of the studied population in the Azov-don basin. To assess the biological characteristics of wild carp, ichthyological control catches were carried out in the waters of the Taganrog Bay and its near-Delta part, in the Don. To interpret our results and to get a complete picture of the state of the carp population, we analyzed literature sources covering the subject under study, as well as survey data of Amateur fishermen in the study area. The source and reasons for the introduction of carp — a domesticated form of carp-into the river and Bay are described. Genetic contamination of wild carp in the lower river Don and Taganrog Bay is suggested.

Progress and Challenges in Poliomyelitis Eradication. Vaccine evolution (review) Progress and Challenges in Poliomyelitis Eradication. Vaccine evolution (review) Belova Olga Evgen’evna FSRI SRC VB «Vector», Koltsovo, Novosibirsk reg., Russia  Abstract: Poliomyelitis is an infectious viral disease caused by three serotypes of poliovirus. It affects the central nervous system and can cause paralysis. There are two effective vaccines that protect against polio - inactivated (IPV), given by injection, and live attenuated oral polio vaccine (OPV). The vaccination campaign, before it was halted by the coronavirus pandemic, almost succeeded in eradicating polio. Since 1988, the number of wild poliovirus cases has decreased by more than 99%. But in recent years, efforts to eradicate poliomyelitis have been hampered by outbreaks of vaccine-derived poliovirus, in which OPV recipients have isolated mutant variants of Sabin's stool strains that could become pathogenic vaccine-derived polioviruses and circulate through the population, causing disease in unvaccinated people. Polio will only be completely eradicated when all sources of the virus, including wild poliovirus (WPV) and vaccine-derived poliovirus (VDPV), are eliminated. There are now more VDPV cases of polio worldwide than WPV, and continued use of Sabin's OPV has resulted in additional outbreaks of VDPV. To eradicate poliovirus completely, a safer, more genetically stable, live attenuated vaccine is needed. The article summarizes the progress in global polio eradication and current challenges. The desired characteristics and new technologies for the production of vaccines, which can be used in conditions of complete elimination of the virus, are considered. The progress in the development of improved OPV strains based on innovative strategies is analyzed.

Humus horizons of chernozems in the Russian soil classification system: current proposals Eng. Humus horizons of chernozems in the Russian soil classification system: current proposals  Khitrov Nikolay Borisovich1, Bezuglova Olga Stepanovna2, Gerasimova Maria Innokentievna3 1V.V. Dokuchaev Soil Science Institute, Moscow, Russia, khitrovnb@gmail.com 2Southern Federal University, Pastov-na-Donu, Russia, lola314@mail.ru 3M.V. Lomonosov Moscow State University; V.V. Dokuchaev Soil Science Institute, Moscow, Russia, maria.i.gerasimova@gmail.com   Abstract: Identification of soil type taxonomic units in the new Russian Soil Classification is based on combinations of diagnostic horizons, and the topsoils in all chernozems are qualified as dark-humus (AU) diagnostic horizon in “virgin”soils, and agrodark-humus (PU) one in arable soils. However, the dark-humus horizon occurs in other soils, and its properties are somewhat different there. For a more adequate diagnostic of chernozems, which is required for solving either pedogenetic, or applied problems (including the ecological issues), it is proposed to introduce in the updated version of the Russian Soil Classification system a new diagnostic horizon – black-humus (AN) horizon specifying chernozems among other soils. The AN horizon differs of the AU horizon by its monochromic color, high pedality with strong structure, quality of humus, physical properties, fertility and resilience to human impacts. This pair of horizons resembles chernic and mollic horizons in WRB. It is also discussed whether it is feasible to introduce the arable derivate of the black-humus horizon (PN), since its properties have much in common with those of the dark-humus horizon.  

Pollutants as a factor in the degradation of alpine glaciers DOI:  Pollutants as a factor in the degradation of alpine glaciers Abakumov Evgeny V.1, Tembotov Rustam Kh.2 1 St. Petersburg State University 2 Tembotov Institute of ecology of mountain territories Russian Academy of Sciences, Nalchik Abstract: Pollutants are an important factor leading to glacier degradation. Black carbon is one of the substances contributing most to the thawing of snow and ice cover. It results from incomplete combustion of fossil fuels, emissions of diesel engines for transport and industrial purposes, as well as forest fires and burning of agricultural waste. Sedimenting on the cover of glaciers, black carbon reduces the albedo of the surface, which in turn leads to their heating and further thawing. This is extremely important for mountain areas. This review considers the current modern effects of pollutants, including black carbon, on the degradation of glaciers in mountain regions, on the example of the Central Caucasus. The work shows that the mountain glaciers of the Central Caucasus are gradually, although unevenly melting and the cause is not only global warming, but also pollutants settling on their surface. The transport routes and sources of glacier pollution are shown. Air masses from the Middle East, Eastern and Southern Europe, as well as northern Africa, have been identified as the main sources of pollutants in the Central Caucasus. The only paper on black carbon in the Central Caucasus states that in the first half of the 20th century, anthropogenic emissions from Europe led to a 1.5-fold increase in black carbon concentrations on Elbrus. Forest fires and agricultural waste incineration are also shown to be the main regional sources of black carbon in the North Caucasus. Industrial production in the North Caucasus is poorly developed and does not contribute significantly to black carbon emissions and thus the deglacification of Central Caucasus glaciers.  

The species composition, structure and spatial distribution of the alien component of the flora of the South of the Russian Black Sea region The species composition, structure and spatial distribution of the alien component of the flora of the South of the Russian Black Sea region Egoshin Alexey Valentinovich Sochi National Park, Sochi, Russia; e-mail: avegoshin@gmail.com  Abstract: The species composition of the alien flora of the South of the Russian Black Sea coast is given. The analysis of taxonomic, biomorphological, hygromorphic spectra of introduced species is carried out. The alien component of the flora is classified according to the degree of naturalization, origin, and time of introduction. It has been established that the alien component of the flora of the region is most represented by species of the families Amaranthaceae, Asteraceae, and Poaceae. By the method of introduction, most alien plant species confined to disturbed habitats. At the same time, the homeland of 41% of all unintentionally introduced species of the region is the Americas. As a result of spatial modelling, it was found that the bioclimatic conditions of the research area are most comfortable for growing only 74 of the 182 most aggressive alien plant species. The zoning of the study area was carried out. It was established that the area of ​​the most invasive-dangerous area of Greater Sochi is 1222.2 km2 (36 %).

Methodology for assessing the natural resource potential of agricultural landscapes in Russia Methodology for assessing the natural resource potential of agricultural landscapes in Russia Shpedt Alexander Arturovich1,2, Trubnikov Yury Nikolaevich1 1Krasnoyarsk Agricultural Research Institute, Federal Research Center «Krasnoyarsk Science Center SB RAS», Krasnoyarsk, Russia   2Siberian Federal University, Krasnoyarsk, Russia   Abstract: A method for assessing the natural resource potential (PRP) of agricultural landscapes in Russia is proposed. Evaluation PRP is carried out for soils used in agriculture. Agro-climatic indicators that determine the productivity of agricultural crops are taken into account: the sum of temperatures above 10°C and the annual amount of precipitation. All soils and agro-climatic parameters are ranked in points from 5 to 100. It is proposed to use information and logical analysis to calculate the final PRP of the agricultural landscape. In the equations, the estimated indicators are arranged as the impact on the crop decreases. Agricultural landscapes are evaluated taking into account soil properties and two important agro-climatic parameters that characterize the conditions of heat and moisture supply. These formulas are "open", which allows you to enter other informative, estimated indicators in them.  

Association Galio biebersteinii–Cephalarietum coriaceae Demina ass. nov. prov. within Karachay-Cherkessia Association Galio biebersteinii–Cephalarietum coriaceae Demina ass. nov. prov. within Karachay-Cherkessia Demina Olga N. 1, Rushchuk Alexandr D., Rogal Lyudmila L.2, P. Dmitriev Pavel A.2, Borlakova Fatima M.1 1Karachay-Circassian State University named after U. D. Aliyev, 2 Southern Federal University, Rostov-on-Don, Russia   Abstract: D. S. Dzybov points to Bothriochloa ischaemum communities’ commonness in the North Caucasus [5], however syntaxonomic study of the Rocky ridge vegetation is absent on the territory of KChR in this regard [19]. N. L. Tsepkova does not consider low-mountain steppes with participation of Bothriochloa ischaemum, addressing to a syntaxonomy of nearby located mountainous meadow steppes of Central Caucasus Mountains [13]. Mountainous types of vegetation [16]. The studied communities with participation of Bothriochloa ischaemum represents meadow stony steppes of the North Caucasus low-mountains. They are xeromesophilic and integrated in a new association Galio biebersteinii-Cephalarietum coriaceae. Community subassociation G. b. – C. c. stipetosum caucasicae is the reflection of more insolated, often droughty ecological conditions. Diagnostic species are rare and endangered, many of them are included in to the Russian Federation and KChR Red Lists. B. M. Mirkin's work with coauthors [11] was used at decision-making in the syntaxonomic analysis. Studied communities are similar to stony vegetation of Central and Southeast Europe massif in structure and physiognomy – xerophilous open steppe grass communities on the surface of stony limestones and silicic substrates presented at Stipo pulcherrimae-Festucetalia pallentis Pop 1968. The allocated North Caucasian association Galio biebersteinii-Cephalarietum coriaceae cannot be carried to one of three alliances of an order of Bromopsietalia cappadocicae Saitov et Mirkin 1991 (Bromopsietalia cappadocicae Didukh in Saitov et Mirkin 1996), allocated for xerophilous grass dwarf semishrub vegetation of the Mountain Crimea [12] and later the order of Stipo pulcherrimae-Festucetalia pallentis, accepted as a synonym [18], due to the lack of diagnostic species of these alliances as the analysis of the available syntaxonomic material of adjacent territories showed. The North Caucasian association Galio biebersteinii-Cephalarietum coriaceae is offered to be considered as a part of a new alliance, including vegetation of limestones exposures of low mountains of the southern slope of the Rocky ridge, at this level of syntaxonomic analysis.  

Transformation of morphological properties of soils of the Gorlovsky coal basin under the influence of anthropogenesis Transformation of morphological properties of soils of the Gorlovsky coal basin under the influence of anthropogenesis  Dvurechenskiy Vadim G. Novosibirsk State University of Architecture and Civil Engineering (Sibstrin); Russia; E-mail: dvu-vadim@mail.ru Abstract:   In the nineteenth century, V. V. Dokuchaev argued that soils are formed according to the action of 5 factors of soil formation. In the 21st century, the sixth factor, anthropogenic impact, is increasingly manifesting itself. In places of mining, anthropogenesis manifests itself to the highest degree. It will never be possible to restore the original appearance of the territory, since according to the laws of genetic soil science, if at least one soil formation factor is changed, soils will be different. Morphological properties, as the most indicative, give an idea of the quality of soils formed in landscapes exposed to the sixth factor of soil formation. The article reflects the features of the formation of soil cover, which morphologically differs sharply from background soils - leached chernozems. Embryozems of anthropogenic landscapes of the Gorlovsky coal basin should be considered as azonal soil formations. The azonality of embryozems leads to the emergence of new ecological systems with a number of distinctive features from zonal ones, the main of which is the formation of soils with a small set of soil functions. As a result of the study, an unsatisfactory soil and ecological assessment of the territory that underwent anthropogenesis is given, because after 35 years from the initial phase of anthropogenesis, embryozems of the primary stages of soil formation are determined in the soil cover - initial and organo-accumulative and there are no embryozems of the late stages of soil formation - soddy, the more humus-accumulative. Trends in the direction of soil development in a disturbed ecosystem are determined: the formation of azonal dry-steppe soils and various subtypes of organo-accumulative embryozems is assumed as part of the soil cover. Ways are suggested to restore the landscape transformed by man, namely, to form technozems with a high set of soil and environmental functions.  

Soil water quality and winter wheat yield depending on the method of main processing and the precursor on the erosion-dangerous slope Soil water quality and winter wheat yield depending on the method of main processing and the precursor on the erosion-dangerous slope   Rychkova M. I. Federal Rostov agricultural research center, Rassvet village, Russia, E-mail: rychkova-1980@list.ru Annotation: The article presents the results of research to determine the influence of different methods of basic soil treatment and the predecessor of winter wheat on the water quality of ordinary chernozems and productivity in conditions of erosion-dangerous slope. It was found that the use of chisel as the main soil treatment had a positive effect on the structure of erosion-dangerous black earth soils, increasing not only the water strength of aggregates, but also the water strength coefficient, which contributed to an increase in soil resistance to water erosion. The highest coefficient of soil water quality was observed when chiseling pure steam from the precursor. When sowing, it was 3.71, during the renewal of the spring growing season it increased to 4.26, and when harvesting, it increased to 4.65. The highest yield of winter wheat of 3.99 t / ha was formed with the chisel method of soil treatment according to the precursor pure steam.  

Ecological condition of depressed soils of dry zone of Kazakhstan Ecological condition of depressed soils of dry zone of Kazakhstan   Rakhimgaliyeva Saule, Yesbulatova Altyn   Zhangir khan West Kazakhstan Agrarian - Technical University, Uralsk, Kazakhstan; saule-ra@mail.ru   Abstract: Since the beginning of the 90s, arable soils have ceased to be cultivated, arable land has gradually transferred to fallow lands, and the fertility of fallow lands has deteriorated. Gradually, on fallow soils, weed vegetation began to grow. The soils of these areas have degraded. The soils of fallow areas have not been surveyed for a long time. The aim of the study was to study the effect of organic-mineral fertilizers on the fertility and productivity of the granary. The subjects of research are dark chestnut soils. The classification of 1977 is still in effect in Kazakhstan; in Russian Federation, a new classification of soils has been adopted, where these soils are called texture-carbonate chernozems. Alkaline hydrolyzable nitrogen characterizes potential soil fertility. The alkaline hydrolyzable nitrogen in 0—20cm layer contents 77—105 mg/kg of soil. In a layer of 20-40 cm is from 70 to 98 mg / kg of soil. That is, both in the 0—20 layer and in the 20—40 cm layer, the content of alkaline hydrolyzable nitrogen is high. According to the content of labile phosphorus, fallow soil is characterized by a low and medium degree of availability. It is provided with medium potassium. The studied soils are characterized by low natural fertility; the humus content in the surface soil layer does not exceed 3,85 %. As a result of the processing of fallow soils, the introduction of organomineral fertilizers and wheat grass crops, the soil fertility was improved.  

Meadow- brown soils of the Southern slope of the Great Caucasus by International classification Meadow- brown soils of the Southern slope of the Great Caucasus by International classification Huseynova Sultan Maharram gizi Institute of Soil Science and Agrochemistry of the National Academy of Sciences of Azerbaijan, AZ 1073, Baku, st. M. Rahim 5; sultanhuseynova@rambler.ru Abstract: The aim of the research was to study the diagnostic features of the meadow-brown soils (irrigated meadow-brown merged, meadow-brown cultivated, meadow-brown carbonate) of the southern slope of the Greater Caucasus and give the name to these soils in accordance with the International Classification Soils on the Reference Base (WRB) in 2015. The objects of research are meadow-brown soils of the southern slope of the Greater Caucasus. Field experiments and analyzes on soil samples were carried out by standard methods. The paper deals with the main features of meadow-brown soils of the southern slope of the Greater Caucasus, their distribution, relief, climate, vegetation, morphological description, basic genetic signs (content of humus, exchange nitrogen, ratio of C:N, pH, cation exchange capacity, granulometric composition) and soil classification. For the first time, an attempt was made to give the name meadow-brown soils (irrigated meadow-brown merged, meadow-brown carbonate) according to the international classification of soils based on the Reference Base (WRB). With the different principal and supplementary qualifiers all soils were classified as Cambisols.
