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.

Assimilation of basic nutrients from soil and mineral fertilizers of grain wheat on the black grain of the podzolized sand of the Right-bank Forest-steppe of Ukraine The effect results of prolonged use of different doses and ratios of fertilizers on chernozem podzolized in a field crop rotation under the conditions of Right-Bank Forest-steppe of Ukraine on the content of essential nutrients in winter wheat grain and straw, the precursor of which was soybean, were shown. It has been found that, due to different doses, ratios and types of fertilizers, the nitrogen content of winter wheat grain increased by 13–49%, phosphorus by 3–19%, and potassium by 6–14%. With grain, winter wheat absorbs nitrogen most – 49.4–147.8 kg/ha and phosphorus – 22.1–51.9 kg Р2О5/ha, and potassium – only 15.0–32.6 kg K2О/ha, depending on yield and quality. It is estimated that 27–33% of nitrogen, 35–36% – of phosphorus and 74–76% of potassium are returned to the soil with winter wheat straw from economic removal depending on fertilizer doses. Keywords: winter wheat, podzolic heavy clay loam chernozem, content of nitrogen, phosphorus and potassium, economic removal.

It was found that inoculation with nitrogen and application of mineral fertilizers before sowing the seeds of bean crops grown as a secondary crop after winter wheat affected the agrochemical and microbiological properties of the soil. Inoculation of bean seeds with nitrogen before sowing and application of mineral fertilizers in different doses provided an increase in the amount of humus in the topsoil (0-30 cm) layer by 0.021-0.034% compared to the initial values, and the total nitrogen content by 0.006-0.009%. It was found that the increase in the number of mineral fertilizers in the background inoculated with nitrogen before sowing the seeds of beans grown as a secondary crop led to an increase in the number of ammonifiers, oligonitrophils, micromycetes, and actinomycetes compared to the control option.

The effect of application of different doses and combinations of mineral fertilizers in field crop rotation on the content of basic nutrients in plants, economic and relative removal of winter wheat, corn, spring barley and soybeans was studied. Soil - Luvic Chernic Phaeozem. The scheme of the experiment includes 11 variants of combinations and separate application of mineral fertilizers and, including the variant without fertilizer. It was found that the level of nitrogen content of easily hydrolyzed compounds in the soil significantly affects its content in the grain of spring barley, corn, soybeans (R2 = 0,92–0,93), less - winter wheat (R2 = 0,63). The content of mobile phosphates in the soil has almost the same effect on its content in the main and non-commodity part of the crop, regardless of the crop (R2 = 0,39–0,70). The smallest relationship between the content of mobile compounds in the soil and in the crop was in potassium, but in soybean seeds and straw of spring barley and soybeans it was clearly traced (R2 = 0,53–0,68). Nitrogen (64,4–149,9 kg / ha) has the largest share in the economic extraction of nutrients with grain and seed yield, followed by phosphorus – 21,1–51,4 kg P2O5/ ha, depending on the crop. On the formation of the crop unit of marketable and the corresponding amount of non-marketable crop products absorb nutrients in the following ratio N : P2O5 : K2O: winter wheat – 1 : 0,4: 0,7; corn – 1 : 0,3 : 0,8; spring barley – 1 : 0,4 : 0,7 and soy – 1 : 0,4 : 0,4. With the non-commodity part of the crop, nitrogen with corn stalks returns to the soil from economic removal – 28–36 %, phosphorus with soybean straw (47–54 %) and potassium with winter wheat straw and corn stalks – 74–80 %, depending on the experiment variant.

The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.
