The article presents the results of studies of the systematic use of organic and mineral fertilizers on the parameters of fertility of gray forest soil and the formation of productivity of winter wheat. It was found that in a five-saw field crop rotation, the formation of ground backgrounds with different physical and chemical properties is observed. The application of bedding manure at a dose of 60 t on ha and against the background of moderate fertilization rates (N50-100P30-60K50-100) contributed to the neutralization of the soil solution to values of slightly acidic reaction (pH – 5,1), while in the absence of manure (mineral system fertilizers) pHcontinued to remain within the acidic reaction. The organic-mineral fertilization system (12 t on ha of manure + N100P60K100) and organic (12 t on ha of manure per 1 ha) turned out to be effective in terms of the humus of the soil regime, in accordance with the total humus content was 1,30 % and 1,32 % which in percentage terms is 18 % and 20 % higher compared to the option without fertilization – 1,10 %. Optimization of the parameters of the nutrient regime (mobile forms of phosphorus and potassium) of the soil at the end of the rotation was provided by the organo-mineral fertilization system (N100P60 K100 against the background of 60 t on ha of manure). A clear tendency to an increase (by 27 mg on kg) of the content of mobile potassium was determined, compensating for its constant deficiency in the soil, and by an increase of 38 % in mobile phosphorus. The highest productivity of winter wheat (5,45 t on ha) was provided by the organo-mineral fertilization system (60 t on ha of manure + N100P60K100), which is 78 % higher than the control (without fertilizers), under these conditions the greatest increase in protein was obtained – 0,63 t on ha.

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions of the Volga forest-steppe. According to the organic fertilization system, straw of the predecessor, green manure and Biocomposite-correct were introduced into the soil (typical medium-thick medium loamy chernozem) for green manure mass (vetch-oat mixture). The organo-mineral system included two options: straw applied together with nitrogen in a dose of 10 kg per 1 ton of straw and zeolite enriched with amino acids. The mineral fertilizers were nitrogene phosphorus with the NPK content of 16 kg ai/ha, carbamide and potassium chloride. In addition, highly siliceous rock zeolite was applied as a fertilizer. It was found that the use of organic and organomineral fertilizers improves the nutrient regime of the soil; in terms of the content of nitrogen, phosphorus and potassium in the arable layer, these options were not inferior to the option with the use of mineral fertilizers. When introducing zeolite enriched with amino acids, the yield of winter wheat exceeded the option with the use of mineral fertilizers by 0.59 t/ha. The use of organic and organo-mineral fertilizers contributes to the production of environmentally friendly products

The article presents the results of research on the systematic application of organic and mineral fertilizers as the indicators of fertility of gray forest soil and the formation of corn yield per grain. It was determined that in the five-field field crop rotation during the cultivation of the crop, soil backgrounds with different physical and chemical properties were formed. Application of litter manure (direct action) at a dose of 60 t / ha on the background of moderate rates of fertilizers (N40-80R30-60K40-80) contributed to the neutralization of the soil solution to the values of slightly acidic reaction (pH sol. - 5.2-5.3 units), whereas in the absence of manure (mineral fertilizer system) the pH of the salt remained within the medium acid reaction. The most effective in terms of humus condition of the soil was the organo-mineral fertilizer system (12 t / ha of manure + N80P60K80) and organic (12 t / ha of manure per 1 ha of crop rotation area), respectively, the content of total humus was - 1.35 and 1.37% or in percentage terms by 25-27% higher compared to the control (without fertilizers) - 1.08 t / ha. Optimization of nutrient regime (hydrolyzed nitrogen, mobile forms of phosphorus and potassium) of the soil at the end of rotation was provided by the organo-mineral fertilizer system (N100P60K100 against the background of 60 t / ha of manure). The highest productivity of corn for grain (9.49 t / ha) was provided by the organo-mineral fertilizer system (60 t / ha of manure + N100P60K100), which is 86% higher than the control (without fertilizers), under these conditions the largest collection of crude protein was obtained – 0, 98 t / ha.

The research was carried out in 1998-2018 in the conditions of the Komi Republic. Under study was the effectiveness of single application (1983) of lime doses (1.0; 2.0; 2.5 h. a.) and the systematic use of mineral fertilizers (N60P75K75) against the background of lime effect in the cultivation of perennial grass mixtures (meadow clover, meadow timothy and cocksfoot). High efficiency was shown by liming at doses of 2.0 and 2.5 h. a., the effect remained for 35 years since their introduction to the soil. Thus, in 2018, the exchange acidity was 4.5-4.8 pHKCl (the initial 4.1-4.2 pHKCl). A similar decrease was observed in the hydrolytic acidity and the content of exchangeable aluminum in the soil. The amount of humus by 2018 increased to 1.7-1.8 % (the initial 1.4-1.5 %). The average yield of perennial grasses during soil liming at doses of 2.0 and 2.5 h .a. was 24.0-25.1 t/ha of green mass (5.3-5.5 t/ha of good quality dry matter), which is 52.8-59.8 % higher than the variant without fertilizers (15.7 green mass and 3.7 t/ha of dry matter). In the variant with the systematic use of NPK, the exchange acid content of the soil and the humus content remained at the initial level, the amount of the mobile forms of phosphorus and potassium increased to 198 and 121 mg/kg of soil (the initial 42 and 62 mg/kg). The average annual yield of grasses was 25.3 t/ha of green mass (5.4 t/ha dry matter) and was 61.1 and 45.9 % higher than the control. Against the background of the aftereffect of lime flour, the effect of NPK on soil properties was similar to the effect of non-fertilizing cultivation, with the exception of a significant increase in the availability of mobile forms of phosphorus and potassium – up to 254-288 and 148-166 mg/kg, respectively. A high yield of green mass of 28.1-30.7 t/ha (6.4-6.7 t/ha dry matter) was obtained, exceeding the control by 78.9-95.5 %. In these variants, grass mixture of high quality was obtained: the content of crude protein – 13.8-13.9 %; dry matter – 21.8-21.9 %; the content of total phosphorus – 0.92-0.94 %; potassium – 2.93-2.95 % and calcium – 0.79-0.81 %. The amount of nitrates in the feed did not exceed the MPC (147-149 mg/kg dry matter). Long-term studies on sod-podzolic poorly cultivated soil showed that the optimal method for the cultivation of long-term legume-cereal grass mixture was the use of lime flour (2.0 and 2.5 h .a.) and the annual use of N60P75K75.

Soil samples (n = 11) were collected in the chernozem areas of the Czech Republic (the Central Europe) from the topsoil and used as representative samples. All sampling areas have been used for agricultural purposes (arable soil) and they were selected as typical representatives of agricultural soil. These samples represented the soil with same genesis (to reduction differencies between soil types) but with different soil properties (physical and chemical). Complete chemical and physical analyses were made for confirmation of copper adsorption on solid phase: we analysed the particle size distribution, content of oxidizable carbon (Cox), the cation exchange capacity (CEC), supply of exchange calcium, magnesium, sodium, phosphorus and potassium, soil reaction and the total supply of Fe, Al, Mn, Ca, Mg, K, P and N. The strongest simple correlation between analysed soil properties and copper concentration had content of available magnesium (r = 0.44) and available phosphorus (r = −0.51). In the case of multiple correlations (i. e. collective influence of multiple soil properties) had the strongest influence combination of clay, soil reaction, total content of phosphorus, available magnesium and available phosphorus. The main influence of phosphorus and magnesium is evident. We suppose that copper and phosphorus enter into specific complex. Influence of these five soil properties can explain 92.7 % (r = 0.927) changes in the content of copper changes in the experiment.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

The article considers the effect of increasing doses and various combinations of mineral fertilizers applied to the cover crop on the yield and quality of a mixture of perennial grasses of two - years use, as well as the effect of fertilizers on the agrochemical parameters of sod-podzolic light loamy soil. The objects of the study were Stodolich meadow clover and Leningradskaya 204 meadow timothy grass. The studies were carried out in two crop rotations - with standard and reduced single doses of mineral fertilizers. The research results showed that in the years (VIII rotation) when the unit dose of fertilizers was increased to N20P20K25, the yield of perennial grasses was higher compared to the harvest in the VII rotation. The most appropriate dose in the VII rotation on perennial grasses of the 1st year was N30P30K45, on grasses of the 2nd year - doses of N30P30K45 and N40P40K60. In the VIII rotation, the highest yield of perennial grasses of the 1st year of use was obtained at a dose of N160P160K200 (8.4 t / ha), of grasses of the 2nd year of use at doses of N80P80K100 and N100P100K125 (6.5 t / ha). Positive effect of increasing doses of mineral fertilizers on the content of soil organic matter has been noted. On the contrary, the soil acidity increased from 4.7 to 4.3 units with an increase of mineral doses. Higher doses of fertilizers increased the content of mobile forms of phosphorus and potassium in the soil.

Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.

Abstract The research was carried out on a permanent fertilization field in the area of the Rzeszow Foothills Region, with Haplic Luvisols formed from loess. The following plants were cultivated in a 4-year cropping system: pasture sunflower, winter wheat, potatoes and spring barley. Various mineral fertilizers NPK + Mg constans and various mineral fertilization NPK + Mg Ca constans were applied in the experiment. Liming was applied in the form of CaO (at the dose of 2.86 t Ca × ha.1). The experiment included 14 fertilizer objects, in 4 replications according to the method of random sub-blocks. Analysis of variance (ANOVA) was applied in statistic processing for a double classification: liming (A) and mineral fertilization (B) . independently of liming. As a result of the testing, it was found that liming raised the content of Cr in Ap and Bt horizons. Mineral fertilization raised the content of Co and Cr in Ap and Bt horizons and Cd and Pb in Bt horizon. The combined effect of liming and mineral fertilization decreased the content of Ni and Co in Ap horizon and Cd in Bt horizon and raised the content of Cr in Ap and Bt horizons and Pb in Bt horizon.

Objective. To determine the features of potential N2O emission from the rhizospheric soil of plants under different crop fertilization systems. Methods. Field experiment, gas chromatographic methods. Results. In the field stationary experiment on leached chornozem during crop rotation in potato, spring barley, peas and winter wheat, it was shown that potential N2O losses from the rhizo-spheric soil of plants depend on fertilizing systems and microbial preparations. The losses of nitro-gen gaseous compounds are proportional to the standards of the applied mineral nitrogen fertiliz-ers. High N2O emission rates are observed in the first year of cattle manure application and during its after-effect. Emission of nitrous oxide also increases with organo-mineral fertilization. The use of microbial preparations in crop cultivation technologies: Biogran for potatoes, Mikrogumin for spring barley, Rhizogumin for peas, Polimiksobakteryn for winter wheat under the application of mineral fertilizers, contributes to a significant limitation of nitrogen gas losses. This is due to the increase of the absorption coefficients of the active substance from the fertilizers by bacterization-initiated plants and, consequently, the decrease in mineral nitrogen compounds in the rhizospheric soil. When growing potatoes by an organic agrarian background (40 t/ha of manure), the signifi-cant effect of Biogran on the course of the biological denitrification process has not been estab-lished, which can be explained by the formation of an intense pool of microorganisms under the use of manure, and the levelling of pre-sowing bacterization due to this effect. Conclusion. The use of microbial preparations for inoculation of agricultural seeds helps to reduce the emission of nitrous oxide from rhizospheric soil of plants under their cultivation by mineral agrarian backgrounds, which is important both economically and environmentally.

Results of studying effect of mineral fertilizers in combination with inoculation with nitrogen-fixingbacteria on chickpea productivity in podzolic black soil of Right-Bank Forest-Steppe of Ukraine havebeen shown. Pre-sowing bacterization contributed to the active formation and functioning of thesymbiosis, provided that the background of nitrogen fertilizers did not exceed 60 kg/ha. Under theinfluence of mineral fertilizers both separately and in combination with seed inoculation, chickpea yieldincreased by 10.8–15.2 hwt/ha compared to the variant without fertilizers and without inoculation.It was established that in order to obtain high and stable yields of chickpea seed in podzolic blacksoil of Right-Bank Forest-Steppe of Ukraine with low content of nitrogen of alkalihydrolyzing compoundsand high content of mobile phosphorus and potassium, its fertilization system should include applicationof phosphate and potash fertilizers in the dose of 60 kg/ha during primary tillage, and nitrogen fertilizers– for presowing cultivation. Before sowing, seeds should be processed with the suspension of ammoniummolybdate and Ryzobofit.
