The results of research on the study of the influence of soil processing systems and fertilizer using co-product for sown clogs and the yield of agricultural plants in a short-growing crop rotation are given. The influence of soil processing systems and fertilizer using co-products for sown clogs and the yield of agricultural plants in a short-live crop rotation is investigated. It has been established that on dark gray soil use in crop rotation of unifituted soil treatment systems contributes to an increase in the level of sown clogging (barley of the corn on grain at 1.4–1.6, wheat winter of winter of winter in 1.4–1.8 times) Due to the accumulation of the main amount of weed seeds in the upper soil layer. The system of fertilizer with by-products at the beginning of the vegetation of plants stimulates the germination of weeds. On average, over the years of research, the abundance of weeds in cropping crops at the beginning of vegetation when using unifituted soil treatment systems was 213–362 pcs/m2, dismissal – 94–108 pcs/m2, and before harvesting was noted a decrease in clogging, respectively, 29–57 pcs/m2, 10–13 pcs/m2. The air-dry weight of the weeds of the highest was with surface soil processing using co-product fertilizer (81.3–85.4 g/m2) relatively with dumping soil treatment (21.7–23.3 g/m2). The highest grain grain of wheat winter – 6.91 and 6.50, corn – 11.47 and 11.74, barley of the yarn – 5.37 and 5.13 and the rape of winter – 3.08 and 3.19 t/ha received when Discalled by 20–22 cm and shallow 10–12 cm soil processing system. With a 6–8 cm surface, the yields of crops decreased by 1.45, 3.66, 1.69 and 0.31 t/ha correspond to plants. A significant reason for reducing plant yields in versions with unifituted soil treatment systems served as a clogging factor, because the level here was higher than when the soil processing.

The aim of the research is to establish the peculiarities of the formation of the nutrient regime of gray forest soil with different systems of basic cultivation, fertilization and sealing of by-products of crops in short-rotation 4-field grain crop rotation – winter wheat–corn for grain–barley–soybean. Evaluate the quantitative inflow of biomass, participation in the formation of the nutrient regime of gray forest soil, especially the differentiation of 0–40 cm of soil layer depending on the distribution of nutrients in different tillage soil systems. The studies were carried out in a long-term stationary experiment of the department of soil cultivation and weed control of the NSC «Institute of Agriculture of the NAAS», founded in 1969. The fertilization system consisted of the application of mineral fertilizers N65Р58К68 kg acting things per 1 ha of crop rotation area. As an organic fertilizer, we used by-products of crop rotation, where during 2009–2013 received an average of 5,17–5,50 t/ha, and 2014–2017 – 6,65–7,76 t/ha of crop rotation. The existing yield of the main product significantly influenced the volume of the non-commodity part, with the growth of the main product, the growth of by-products also took place in direct proportion. Nitrogen removal averaged 105 kg/ha, and with biomass it returned on average 55,4 kg/ ha, nitrogen with a full mineralization cycle, in general, this corresponds to 45–47 % of the share of costs. In general, the return of phosphorus from by-products for the rotation of 5 received an average of 12,0–16,7 kg/ha and 4-field crop 26 rotation 19,5–22,0 kg/ha, which was 35–40 % of the total removal harvest. The soil received many times more potassium from the biomass of agricultural crops than part of the cost of the main product, due to the attraction of the maize leaf mass, from which an average of 177–253 kg/ha enters the soil, and for crop rotation – 61,4–95,4 kg/ha per hectare of sown area. Key words: gray forest soil, soil nutrient regime, recycling of nutrients, main and by-products of crops.

Purpose. Identify the features of changes in the factor of potassium capacity of dark gray soil under long-term systematic application of different doses of mineral and organic fertilizers. Methods. Field, laboratory, mathematical and statistical. Results. At various intensities of fertilizer systems and fertilizer ratios, it has been established that the long (30 years) use of organic and mineral fertilizers contributed not only to stabilization but also to the restoration of the stock of moving potassium in the arable soil layer in comparison with the initial data (1987).The growth of mobile potassium content was consistent with the increase in the agrochemical load in crop rotation. Conclusions. Long-term systematic application for 1987–2000 years mineral fertilizers in doses of 265–397 kg of NPK on the background of 10 tons of manure per 1 ha of crop rotation, in 2001–2010 years – 211–316,5 kg of NPK per 1 ha, and in 2011–2017 years – 217,5–326,4 kg of NPK per 1 ha on the background plowing crop by-products had a significant impact in the factor on the capacity factor of potassium of dark gray podzolized soil, ensuring it is elevated and very high level.

Objective. To establish the influence of soil treatment methods on the number of earthworms and microbial biomass in dark-chestnut heavy loam soil with observance of the following crop rotation: soybean – winter wheat – corn; verify the hypothesis of the negative influence of traditional soil treatment technologies on the number of earthworms. Methods. Analytical, field, laboratory, system analysis, statistical. Results. During the studies conducted in 2018–2021 at Askanian State Agricultural Experimental Station of the Institute of Irrigated Agriculture of the NAAS, the positive influence of zero soil treatment technologies on the studied parameters versus with traditional technologies was established. A 2.5-fold increase in the number of earthworms and a 1.1-fold increase in microbial biomass was reported with zero soil treatment technologies. The interaction between soil treatment factors and cover crops in the structure of crop rotation was 23.7 %. Soil treatment technologies had a negligible influence on the size of microbial biomass — at the level of 1.4 %. The significance of the action of cover crops in crop rotation was 10.0 %. The experiment also showed a higher number of earthworms in the soil with zero soil treatment technologies with cover crops and traditional technologies for control, due to better live environment and favourable conditions for reproduction and distribution of the population depending on soil treatment technologies. Changes in the density of the soil layer 0–30 cm were within the measurement error (for zero soil treatment technologies the studied parameter was 1.23 g/cm3, for traditional — 1.24 g/cm3). Compaction of 0–20 cm soil layer with zero and traditional soil treatment technologies was reported. The content of soil organic matter by the years of studies under zero soil treatment technologies increased to 3.0 %, which is 1.2 times higher than with traditional technologies. Conclusion. Under the conditions of stationary field experiment the positive influence of zero soil treatment technologies on early changes of biological properties of soil, which were characterized by increase in number of earthworms and size of microbial biomass, has been established. The positive influence of cover crops on soil quality was determined, which was characterized by signs of biota activation in the 0–30 cm layer and improvement of biological and physical properties of the soil.

In a multifactor stationary field experiment on the area of the Elitnoye Holding in the Novosibirsk region (central forest-steppe subzone) in 2002-2018 the seasonal dynamics of nitrate nitrogen in the fields of four full grain-steam crop rotation by steam and grain predecessors against an extensive background (without chemical means) in four versions of the main mechanical treatment of leached black soil was investigated. Along with this, the productivity of grain crops was studied with long-term minimization of the main tillage on extensive and intensive backgrounds. The authors found out that in the central forest-steppe of the Ob river region before sowing grain crops according to the various methods of steam preparation most of all in the meter layer of nitrate soil was found in black steam with plowing (150 kg / ha) and less in variants with soil-protective treatments (132-141 kg / ha ). The lowest level of this element in the soil (124 kg / ha) in spring was noted by the early minimum steam. Before sowing the second wheat after steam, the nitrate nitrogen content in the meter soil layer for plowing (79 kg / ha) was slightly higher than in the options with soil treatment (61-64 kg / ha). In the final field of crop rotation, regardless of the studied soil cultivation systems, the minimum initial amount of nitrogen (56-57 kg / ha) was noted. By the end of the growing season of crops, the nitrate content in the soil was sharply reduced. Before harvesting wheat by steam, the nitrogen content in the upper meter profile was 41-55 kg / ha, for grain precursors even less - 27-33 kg / ha. The steam yield of grain crops on extensive and intensive backgrounds was 3.09-3.21 and 3.96-4.02 t / ha, respectively, and practically did not depend on the methods of its preparation. On repeated sowing the wheat yield in comparison with an extensive background in plowing (1.26-1.79 t / ha) was significantly higher than in the studied options for minimizing the main tillage (1.02-1.55 t / ha). When optimizing the mineral nutrition of plants and the phytosanitary situation of crops, wheat productivity by grain predecessors in crop rotation fields increased 2.0-2.9 times without significant differences in soil treatment options.

Objective. Determine the parameters of uptake of organic matter and biogenic elements withby-products of crops under the use of mineral and green-manure-mineral fertilization systems andmicrobial preparations. Methods. Field experiment, agrochemical, balance, statistical. Results.Under the conditions of short crop rotation “winter wheat – intermediate green manure – corn forgrain – soybean – winter wheat”, the influence of microbial preparations Biogran (on the basis ofnitrogen-fixing bacterium Azospirillum brasilense 410 and physiologically active substances) forcorn and Nitro-Legu (on the basis of complex of diazotrophs Bradyrhizobium japonicum, Azospirillum brasilense and polysaccharide) for soybeans on crop yields, uptake of by-products in the soil,balance of nitrogen, phosphorus and potassium depending on fertilization systems. Under exposureto biopreparations, uptake of corn by-product in the soil increased by 1.41–2.12 t/ha, soybeans —by 0.51–0.71 t/ha of dry matter, depending on the agrarian backgrounds, which, taking into account the humification factors, can provide soil replenishment with humus at the level of 0.31 to0.47 t/ha and 0.12–0.17 t/ha, respectively. Nitrogen and phosphorus balances, as well as their intensity under the mineral fertilization system were positive. Green-manure-mineral fertilization system and pre-sowing bacterization of seeds helped to improve the parameters compared to the mineral fertilization system. Potassium balance was slightly deficient (–16.2 to 20.4 kg/ha at a balanceintensity of 78–80 %) under exposure to the mineral fertilization system and positive under exposure to green-manure-mineral system. Microbial preparations helped to improve parameters. Additional uptake of the biogenic element compounds in the soil provided an increase in the yield ofwinter wheat. According to the results of the evaluation of the balance of the key nutrients, a satisfactory ecological balance was created in the short crop rotation under exposure to green-manuremineral fertilization system and pre-sowing bacterization of corn and soybean seeds. Conclusion. Upon evaluation of the efficacy of microbial preparations in crop cultivation technologies, theparameters of uptake of organic matter and biogenic element compounds with by-products in the arable soil layer should be taken into account along with their direct effect on yield formation andproduct quality.

Identify the features of changes in the factor of capacity of phosphates in the dark gray soil in long-term systematic application of different doses of mineral and organic fertilizers. Methods. Field, laboratory, mathematical and statistical. Results. By varying the intensity of fertilizer systems, it found that long-term (28 years) application of organic and mineral fertilizers contribute to not only stabilize but also the reproduction of the stock of mobile fraction of phosphates in the arable soil layer, compared with the original data (1987). The growth of mobile phosphorus content was consistent with the increase in the agrochemical load in crop rotation. Conclusions. Long-term systematic application for 1987–2000 years mineral fertilizers in doses of 265–397 kg of NPK on the background of 10 tons of manure per 1 ha of crop rotation, in 2001–2010 years – 211–316,5 kg of NPK per 1 ha, and in 2011–2015 years – 213,8–326,4 kg of NPK per 1 ha on the background plowing crop by-products had a significant impact of changes in the factor of capacity of phosphates regime, ensuring the enrichment of dark gray soil available to plants mineral phosphates.

Aim. To substantiate the agroecological estimation of the performance of a short crop rotation in conditions of intense and organic system of fertilization on the basis of restoring normative parameters of emission and se- questration of С-СО 2 circulation while using by-products as organic fertilizers in conditions of modern climatic system of the Forest-Steppe of Ukraine. Methods. Field, statistical, laboratory. Results of Investigations. The performance of short crop rotations is determined by the capacity of С-СО 2 balance. Strong inverse correla- tion was found between the capacity of N and the ratio between C and N in the agrocenosis, which demon- strated that enhancing the humifi cation processes (ratio constriction) led to the increase in the capacity of С org balance and the decrease in the capacity level of С-СО 2 balance (enhancing mineralization), related to the reduction in the performance of crops in the agrocenosis of a crop rotation compared to the organic system of fertilization. The capacity of С-СО 2 and С org balance correlates at the medium level of inverse direction, and the yield of the main products, feed units and digestible protein correlates at the level of strong direct correlation. Conclusions. General mineralization of by-products and humus in the agrocenosis and humifi cation processes are antagonists, so extending the ratio between С and N at the intense fertilization system stimulates the in- crease in performance and reducing С to N similar to the organic fertilization system enhances the humifi cation process due to binding of С org into humus and limits mineralization which leads to the reduction in agrocenosis performance at the organic fertilization system.

In recent years, there has been an increasing interest around agricultural science and practice in conservation tillage systems that are compatible with sustainable agriculture. The aim of this study was to assess the qualitative and quantitative changes in weed flora and soil seed bank under reduced tillage and no-till (direct sowing) in comparison with traditional ploughing. In the crop rotation: pea/rape—winter wheat—winter wheat the number and dry weight of weeds increased with the simplification of tillage. The seed bank was the largest under direct sowing and about three times smaller in traditional ploughing. Under direct sowing, most weed seeds were accumulated in the top soil layer 0–5 cm, while in the ploughing system most weed seeds occurred in deeper layers: 5–10 and 10–20 cm. In the reduced and no-till systems, a greater percentage of perennial and invasive species, such as Conyza canadensis L., was observed. The results show that it is possible to maintain weed infestation in the no-till system at a level that does not significantly affect winter wheat yield and does not pose a threat of perennial and invasive weeds when effective herbicide protection is applied.

The article presents data on the study of the main nutrition elements in the soil under maize crops, depending on the predecessors and methods of soil treatment in the conditions of ordinary Chernozem. The object of research is a Krasnodarsky 194MV hybrid of maize. Variants: 1. Fallow arable land (control); 2. Lupine as green manure; 3. Peas as green manure; 4. Binary sowing of lupine and peas as green manure; 5. Soy as green manure. The experiment was repeated three times, field placement was randomized, and area of each was 120 m². Agrotechnics of maize cultivation in the experiment corresponded to the recommendations for this zone. Green manure was plowed in during its reproduction phase. In the variants with green mass plowing to a depth of 23–25 cm, the largest amount of nitrate nitrogen was in the soil layer 0–20 cm. In the specified soil horizon, before sowing maize, the content of nitrate nitrogen ranged, depending on the variant, from 24.7 mg/kg to 42.8 mg/kg. In the soil layer 20–40 cm, the amount of nitrogen was lower, just 19.4–29.5 mg/kg. Similar dependence was observed for maize during its flowering phase. Tillage methods had almost no effect on the accumulation of nitrate nitrogen in the upper soil layer (0–20 cm). As in all the variants, the differences in this indicator were within the experimental error. However, the content of nitrate nitrogen during the growing season was different. The greatest amount of it was observed during the spring period, both in versions with plowing to a depth of 25–28 cm and in versions with blade loosening to a depth of 10–12 cm. The smallest amount of available phosphorus, regardless of the method of soil preparation, in the layer 0–20 cm was on fallow arable land – 122 mg/kg during the sowing period and 104 mg/kg during the flowering period. In variants with cultivation of legumes as green manure, the content of available phosphorus in the specified horizon was significantly chigher, being 147–171 mg/kg. The highest content of exchangeable potassium was provided by lupine – 209–213 mg/kg in the 0–20 cm soil layer, and lupine sown together with peas – 196–207 mg/kg. The minimum amount of exchangeable potassium was 143–146 mg/kg in fallow arable land, depending on the method of soil treatment.
