At the present stage, it is advisable to use the Unified State Register of Soil Resources of Russia for soil surveys of floodplains.  

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.  

Agrochemical characteristics of mining-heap complexes with various substrata Agrochemical characteristics of mining-heap complexes with various substrata Dmitrakova Y.A., Abakumov E.V. Saint-Petersburg State University Russia, dmitrakovay.a@gmail.com Abstract: With the aim to evaluate of key agrochemical soil characteristics 8 mining-heap complexes were investigated on example of mines for exploitation building materials.  The study sites were located in Leningrad, Novgorod and Tula regions. Objects are presented by 3 limestones, 3 sandy-gravel, 1 phosphorite and 1 fireproof clays mines. All the quarries were presented by maximal diverse ecotopes, where soil pits were created and sampling were conducted.  Soil acidity, total organic carbon and available forms of phosphorous, potassium, ammonia and nitrates were determined in the lab. Data obtained showed that content of nutrients variates within the soil profile depth and this fact illustrate unhomogenety of substrata on heaps. All the ground characteristics are favorable for vegetation development. The only exception was fixed for soil on the pyrite containing ground with extremely acid reaction.  The nutrients content and pH values were strongly affected by relief and reclamation technology, at least it was more pronounced than type of parent material. Despite on popular opinion that substrate of mines are usually poor in terms of nutriens content, in our study their content was comparable or even higher that in natural soils.    

Air masses and pollution transport to some Northern regions of European Russia were studied with trajectory statistics. We used EMEP data on lead and cadmium emissions to the atmosphere from Europe in 2010-2014. This dataset is most suitable for current investigation aiming to separate the contributions to pollution of the Northern Russia environment from sources of European part of Russia (1) and from the rest European territories (2). In some years at some points contributions (2) may be sizable (up to 50% and more), but as a whole the North of European Russia is polluted by the own Russian anthropogenic sources. As calculated, spatial, seasonal, and interannual variations in environmental pollution may be as high as 10 times and more. Spatial variations are determined by different distances between investigation points and the main sources of pollutants. Seasonal variations in air concentrations depend on the difference in deposition velocities for different seasons. Interannual variations in pollution level in Northern regions are caused by diversity of atmospheric circulation pattern, and (in less degree) by emission differences from year to year.

The content of mortmass and biodynamics of arable soil under conditions of real agrotechnology in Siberia Eng. The content of mortmass and biodynamics of arable soil under conditions of real agrotechnology in Siberia Danilova A.A.Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, 630501 Novosibirsk oblast. Krasnoobsk, a/b 356Danilova7alb@yandex.ru Abstract:We reviewed the literature data and the results of our own research in order to show the dependence of the ecologically significant biological properties of the soil on the content of the mortmass. The transfer of virgin soil to arable land leads to the mineralization of mobile organic matter stocks. In the long-term arable soil, all properties, including biological ones, stabilize at a lower level in comparison to the virgin soil. The use of fertilizers for plant nutrition can increase the total soil organic carbon content by only 0.1-0.2%. But the increase of mortmass carbon content can be more significant. Consequently, we have the opportunity to influence the biodynamics of the soil by changing of plant residues amount in the soil. In conditions of 4 grain-crop rotations, the influence of 4 doses of stubble wheat residues (2,2; 6,5; 7,2; 9,5 t/ha in year) on soil properties was studied. In 10 years after the beginning of the observations, the amount of mortmass was accordingly equal to 400, 690, 880, 1040 mg С/kg. The indicators of the biological activity of the soil increased by about 30-50%The relationship between the biological activity indicators and the detoxification activity of the soil was not straightforward.The most optimal dose of plant residues from ecological and agrotechnological positions was a dose equal to 6,5 t / ha, which provided detoxification of pesticides within the current growing season. Thus, there is the posibility to optimize the ecotoxicological situation in the arable soil at the expense of the agrocenosis's own resources.

Diurnal changes of weight and fat reserves in the Eurasian blue tit (Cyanistes caeruleus, Aves) during winter period Eng. Diurnal changes of weight and fat reserves in the Eurasian blue tit (Cyanistes caeruleus, Aves) during winter period Gavrilov Vadim V. S.N. Skadovsky Zvenigorod Biological Station, Biology department of the M.V. Lomonosov Moscow State University,119991 Moscow, Russia; vadimgavrilov@yandex.ru Research was carried out in 1999 - 2018 at Zvenigorod Biological Station (the Moscow Region, Russia, 55o44' N, 36o51' E). Birds were caught by mist-nets. All the birds were banded, fat reserves and weight were determined and then birds were released. In total 58 Eurasian blue tit were caught. The daily rhythm of body weight of Eurasian blue tits can be divided into two periods: from 8 to 13 hours and from 13 to 19 hours. The body weight in the second half of the day - from 13 to 19 hours - is significantly higher than at other times. At night, the body weight of birds decreases. Fat reserves of Eurasian blue tits are maximal at the end of the day, with the last evening hours practically unchanged. Between 16 and 19 hours fat reserves are higher than at other times. Fat reserves decrease throughout the night and continue to decrease in the morning, reaching a minimum at 12 hours, after which they increase.

The eastern boundary of this species is  traced in Russia through the territories of the Kursk, Belgorod and Rostov regions. The objectives of the study: assessment of genetic variability and analysis of phylogenetic relationships between the populations of the mound-building mice in the eastern part of the range, which was insufficiently studied in this respect. As a result of phylogenetic analysis, we found that there are two phylogroups of mound-building mice - eastern and western. The first includes individuals of M. spicilegus from the eastern part of the range (Moldova, Crimea, Rostov Region), the second one – animals from central and southern Europe (Austria, Montenegro, Serbia, Greece). Earlier, subspecies of mound-building mice in southern Europe was identified – M. s. adriaticus. On the phylogenetic tree in our work, this subspecies is allocated to a separate phylogroup. The first phylogroup is ancestral from the Balkan Peninsula, which has a higher genetic diversity, the second one located in the eastern part of the range, characterized by low genetic variability.

Bank voles (Clethrionomys glareolus and C.rutilus) reaction to house mouse odor in large enclosures Eng.  Bank voles (Clethrionomys glareolus and C.rutilus) reaction to house mouse odor in large enclosures Osipova Olga V. 1, Kozhukhantseva Ekaterina A. 2, Kotenkova Elena V. 1 1A.N.Severtsov Institute of Ecology and Evolution Russian Academy of Sciences, Moscow, Russia 2 Moscow State Academy of Veterinary Medicine and Biotechnology – MVA named after K. I. Skryabin, Moscow, Russia Abstract: House mice have got hard odor which seems to protect their territory from the other rodent species. Peculiarities of bank and red voles’ reaction to house mouse odor put upon traps were studied. Visual observations of voles’ behavior near traps with and without mouse odor were conducted in large (120 sq. m) enclosures where voles lived in groups. Species, sex and social status was found to be significant for the type of the reaction. Voles of both species with high social ranks got into the traps with equal frequency and stayed there for equal time. Bank vole males with low social rank avoided traps with the odor. By contrast red vole females preferred to stay in these traps.

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.
