The balance of humus in crop rotations with short rotation on erosion-prone slopes Gaevaya Emma Аnatolievna State scientific institution Don Research Institute of Agriculture  Abstract: The purpose of this work is to study the balance of humus and its reproduction in crop rotations with different content in the structure of the acreage of pure fallow and perennial grasses on the slopes of the Rostov region. Studies were conducted in multifactor stationary experiment, located on the side of the beam Large Log in 2003-2017 years. Experiment was laid in 1986 in the system of contour-landscape organization of the territory of the slope with suppress of 3.5-4°. The soil of experimental plot – the ordinary heavy on loess-like loam. The initial content of humus in the soil at the laying of experiment was 3.80-3.83%. I was studied three crop rotations with different percentages of black allow and perennial grasses in the structure of crops rotations. The article presents data of the post-harvest residues amount and nitrogen entering the soil after different crops. The average values of root and crop residues catering in the soil for a hectare of crop rotation area are presented. The balance of humus is calculated when different doses of fertilizers are applying. The role of balk follow and perennial grasses in maintaining the deficit-free balance of humus was studied. It was shown that to achieve a deficit-free humus balance at the ordinary chernozems in crop rotations, located on erosion-prone slopes of the Rostov region, it is necessary to add organic fertilizer in a dose of 100 kg/ha considering the flushing of the soil. Expanded reproduction of soil fertility is possible if you add organic and mineral fertilizers in a dose of 162 kg/ha and crop rotation with 40 % of perennial grasses.

Comparison of Supervised Classification Techniques and Gaussian Mixture Distribution Method for Estimating Land Use Type on the Landsat 7 Satellite Data The applications of remote sensing on the land cover classification are very important for lands planning. . For this purpose multispectral satellite data uses in agricultural areas due to practically in large-scale. Many of the studies have been carried out with supervised classification based on pixel function. However, it is not possible to determine what kind of uses are in the land where the natural pattern distribution is unknown. For this reason, some statistical approaches and conditional algorithms are trying in the classification. The most common of these is Gaussian mixture distribution analysis (GMD). Mixture distribution analysis is multivariate statistical methods that deal with the separation of objects or different clusters of observations and the re-organization of pre-defined groups. This study was conducted for classification of sugar beet and wheat with grassland by using SC and GMD on the Landsat 7 ETM+ data in 1850 ha areas of Konya region and the spatial ranges were compared with the location realities. The result of calculations has shown the SC estimated sugar beet, wheat and grassland with accuracy coefficients at 0.88, 0.90, 0.83, respectively. On the other hand, GMD predicted with accuracy coefficients at 0.94 for sugar beet, 0.96 for wheat and 0.92 for grassland. As a result, GMD can be used with high accuracy in the detection of different land cover types in unknown lands. However, similar studies should be performed on different types of land cover for creation of spectral libraries, thus GMD could determine all of the land cover types.

Influence of herbicides on the productivity of maize in the conditions of ordinary chernozems in the Rostov Region Eng. Influence of herbicides on the productivity of maize in the conditions of ordinary chernozems in the Rostov Region  Grinko A.V., Polienko E.A. Federal Rostov Agricultural Research Center, Rassvet, grinko82@mail.ru  Abstract. One of the most important ways to increase the yield of corn is to control weed vegetation using chemical protection preparations. It is necessary to assess the level of harmfulness and selection of herbicide. The preparation should correspond to the floral composition of the weeds. In the Rostov region in many cases, the use of herbicidal preparations in the form of tank mixtures is optimal, therefore 6 variants of herbicides from different chemical classes were chosen as the objects of the study. As a result of the research, it was found that the use of combined herbicidal preparations containing several active substances is most effective. This allows to significantly expand the range of action of herbicides and increase their efficiency and payback.  

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.

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.
