Aim. To study the features of phosphorus nutrition of winter wheat under the infl uence of different doses of mineral fertilizers and microbial preparation Polimiksobakteryn. Methods. The phosphatase activity in rhizo- sphere soil of winter wheat was determined photocolorimetrically by the method of Geller and Ginsburg, the phosphorus content in plants – as described by Denizhe in the modifi cation of Bouvatier. Results. The phos- phatase activity in the rhizosphere soil of winter wheat plants increases due to the application of a microbial preparation and mineral fertilizers in low doses. This increases both the absorption of phosphorus by plants and their yield. Conclusions. Growing winter wheat on the leached black soil with dose-relevant introduction of mineral fertilizers in doses, not exceeding N[60] P[60] K[60] , and the use of Polimiksobakteryn improve phosphorus nutrition of wheat plants and promote the increase in the yield of crops.

The paper depicts the research results of development of bacteria of the nitrogen cycle in the root zone of winter wheat plants (variety Sonechko) under the use of microbial preparation Polymyxobacterin and different doses of mineral fertilizers. It was established that split application of fertilizers at doses that do not exceed N60P60K60 and pre-sowing seeds bacterization had optimized the composition of microbial associations in the root zone of plants. The increase of fertilizers doses was followed by the negative changes in the number of bacteria of different functional groups.

The paper depicts the study of mineral nitrogen and pre-sowing seeds bacteryzation on the development of nitrogen fixing bacteria and the activity of autotrophic and heterotrophic nitrification. It was revealed that nitrification activity in the root zone of winter rye plants rises together with the increase of mineral nitrogen doses. Heterotrophic nitrification plays a significant role in the formation of nitrate pool in the root zone, especially during the early stages of plants organogenesis. Application of the microbial preparation Diazobakteryn had enhanced the activity autotrophic and heterotrophic nitrification processes in the rhizosphere soil of plants in the spring, during the early stages of their development while during the next organogenesis phases the reduction of nitrification processes was observed. In plants-free soil the contribution of heterotrophic nitrification to biological transformation of nitrogen was negligible.

It was found, that bacterization of seeds of winter wheat with A. radiobactercontributes to improved phosphatase activity in rhizosphere soil that probably promotes activation ofmineralization process of organic phosphorus compounds in the soil and improves phosphorus nutritionof plants.

Field experiments were conducted in 2017-2020 on the southern black soil in the conditions of the Lower Don. The Doneko winter wheat variety was sown. The predecessor of wheat is corn for grain. Mineral fertilizers were represented by ammonium nitrate (34.4%), nitroammophosk (16-16-16) and carbamide (46%), which acted as a background option in the scheme of the ex-periment. Organomineral fertilizers were preceded by the following agrochemicals: Ruther, Leyli 2000, Alga 1000/Turbo, Siamino Pro, Gumiful Pro, Soft Garden (Master Green Mix) and Double Vine (Monocaliphosphate). In the experiment, options for the joint use of non-root application and pre-sowing seed treatment with organomineral fertilizers were also studied. It was found that the use of organomineral fertilizers Ruther (0.5 or 0.25 l/ton) and Leyli (0.25 l/ton) for seed treatment before sowing, the use of Soft Guard (0.2 l/ha) and Humiful Pro (0.2 l/ha) in spring tillering and in the flag leaf phase against the background of a starter treatment mineral fertilizer in the form of azofoska at a dose of N32P32K32, fertilizing on frozen-thawed soil with ammonium nitrate at a dose of N40 and non-root topdressing with carbamide in the phase, earing at a dose of N20 increased the increase in grain yield on average for 3 years compared to the control variant (farm fertilizer system) by 0.73 t/ha or by 23.0%. The greatest increase in yield from the Router root-forming agent used for seed treatment was 0.36 t/ha or 11.3%. Keywords: WINTER WHEAT, MINERAL FERTILIZERS, ORGANOMINERAL FERTILIZERS, YIELD

Southwest Part

In the conditions of a southwest part of CBR Russian Federation increase in content of alkaline-hydrolyzable and nitric nitrogen and also strengthening of nitrification ability of the soil in the black-soil typical is caused, mainly, by application of the increasing doses of mineral fertilizers, a manure after-action, use of long-term herbs in a crop rotation as predecessors of a winter wheat, and application, mostly, of plowing in the system of the main processing of the soil. The most noticeable variation of contents in the soil of alkaline-hydrolyzable nitrogen is noted for a layer of earth 20-50 cm, and nitrification ability of the soil – in a layer of 0-20 cm. The most significant increase in its contents in a layer of earth of 0-20 cm at a combination of mineral fertilizers and a manure is characteristic of nitric nitrogen, especially on plowing. The tendency to increase in content of nitrates in underlying layers is caused by application of the raised dose of mineral fertilizers under a winter wheat – N120P120K120 N60 (saturation of 1 hectare of the crop rotation area in a grain-grass-tilled crop rotation of N84P124K124 and in a grain-tilled crop rotation of N120P124K124) and an after-action for the fourth year of 40 and 80 ton/hectare of a manure (saturation of 8 and 16 ton/hectare).

The study of different fertilizing systems and microbial preparation Microhumin on the phytosanitary condition of spring barley crops of Hosya variety was performed in the stationary field experiment with short crop rotation (potato – barley – pea – winter wheat) on the leached black soil. Dispersion and development of root rots and rhynchosporium infection, as well as powdery mildew and dark brown blotch was investigated. The decrease in expansion of root rots and rhynchosporium infection on leaves of spring barley was observed in variants with organic fertilizers. The reduction of incidence was observed in variants with mineral fertilizers, especially at medium doses of fertilizers (N60P60K60). Microbial preparation Microhumin had contributed to the improvement of phytosanitary condition of spring barley crops at the combined use with organic and mineral fertilizers.
