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.

The effects of humic fertilizers and preparations on soil fertility Bezuglova Olga S., Polienko Elena A., Gorovtsov Andrey V., Lyhman Vladimir A., Pavlov Petr D. Abstract.  One of the components of biological agriculture is the use of humic fertilizers and preparations, which, unlike chemical fertilizers, may serve as catalysts of biochemical processes in the soil, due to their stimulating effect on soil microorganisms. The paper presents the results of production experiments with humic substances BIO-Don on chernozem ordinary carbonate. Agricultural crops: winter wheat, sunflower, sugar beet. It has been shown that BIO-Don has a positive impact on the dynamics of the mineral nutrients when applied into the soil, and in the topical treatment of vegetative plants. When the mineral nutrients are limited, an increased removal of them from the soil is observed due to the activation of microflora in the root zone. One of the reasons for the positive effect of humic substances on plants is their ability to adjust the content of available forms of mineral nutrients, and as a consequence – to increase the crop yields. The article is prepared on the basis of the plenary report on the second international conference "Problems and prospects of biological farming", held on-line on November 27, 2016.

The effect of humic substances on microbial activity of the soil under fruit trees Gorovtsov Andrey V.,  Bezuglova Olga S., Polienko Elena A., Popov Artem E. Abstract The use of humic preparations for the treatment of fruit trees is one of the most poorly studied aspects of the application of this group of plant stimulators. There is especially little knowledge about the processes occurring in the soil, and virtually no data on the response of soil microbial communities in the root zone to such kind of treatment. The paper presents the data of microbiological analysis of soil under the mature fruit trees (apple, cherry) and young trees in the nursery (cherry, plum) after the treatment with  humic preparation BIO-Don. It has been shown that treatment of fruit trees with humic substances resulted in the activation of many groups of bacteria in the soil under the plants. The most pronounced reaction was observed for oligotrophic and aminoheterotrophic bacteria, a weaker response for reacted aminoautotrophic bacteria, and almost no reaction was noted for oligonitrophilic bacteria, actinomycetes and soil fungi. However, the observed changes in the dynamics of mineral nutrients suggest that the activation of the soil bacteria contributes significantly to the obtained yield increase. The article is prepared on the basis of the plenary report on the second international conference "Problems and prospects of biological farming", held on-line on November 27, 2016.

The effect of humic preparation "BIO-Don" on the balance of mineral nutrients in ordinary chernozem and quality of fruits and vegetables Polienko Elena A., Bezuglova Olga S., Gorbov Sergej N., Dubinina Marina N., Popov Artem E. Abstract: The treatment of garlic and beet plants with humic preparation "BIO-Don" in production environment provided an increase in the mass of bulbs and root-crops by an average of 13-20%, and an increase in diameter by 8%. At the same time an increase in the removal of nutrients from the soil by plants treated with humic substances was noted. The application of humic substances for the treatment of fruit crops by the combination of methods (soil application in drip irrigation and topical treatment) has also led to an increase in the removal of nutrients from the soil: nitrogen and phosphorus  in the spring, and potassium during the second half of the summer. This was accompanied by improvements in the quality of products: a significant increase in the mass fraction of soluble solids (up to 15% relative to control) and titratable acidity (up to 21% of control) in the fruits of cherry and apple trees. The yield of apples was increased by more than 17%. The article is prepared on the basis of the plenary report on the second international conference "Problems and prospects of biological farming", held on-line on November 27, 2016.

Significantly increased the yield of wheat and oats for 3-11 kg/ha, and the increase in number of treatment significant impact has not had. In the grain of spring wheat variety Novosibirskaya 31 gluten content in the application of humic substances increased by 2,1 and 4,8%. In the flowering stage foliar treatment reduced ear grain content and mass fraction of gluten in comparison with the processing in the milk stage. Significant differences between humic preparations Rostok and NOR is not installed.

Reaction of potato varieties to method of application of a humic preparation Rostok Humic preparation Rostok – a natural regulator of growth and development of plants. Apply sprout on potatoes is possible for the processing of tubers before planting and of plants during vegetation. Processing of tubers and potato plants with a solution of Rostok had no significant effect on the number of tubers in the nest of the studied varieties. The Rostock preparation significantly influenced the weight of marketable tubers of all varieties. The increase in average over three years compared to the control was 16-81 %. To a greater extent varieties responded to foliar application of Rostok. The data obtained give reason to recommend humic Rostok as a regulator for growth and development of potato plants and adaptogen in stressful situations when used in tank mixtures with pesticides.
