Carbon dioxide is absorbed by plants during photosynthesis and the intensity of this process depends on the solar radiation coming to this territory, the temperature regime, the availability of moisture and batteries. The amount of CO2 absorbed by plants is determined by the accumulated dry biomass or yield. The potential yield of field crops in production conditions is not always achieved. The paper presents the results of studies on the effect of calculated doses of mineral fertilizers on various types of soils with different moisture indicators on the formation of dry biomass by spring durum wheat. Field experiments were carried out on gray forest soils in 2005-2008, which occupy 43.7% of agricultural land in the Republic of Tatarstan and chernozems in 2001-2003, occupying 39.9%. The assimilation of mineral nutrition elements from soil and fertilizers by plants is influenced not only by the type of soil, but also by the availability of productive moisture. In the studies of 1984-1987, the effect of fertilizers and irrigation on the intensity of accumulation of dry biomass by spring durum wheat was studied. The use of calculated doses of mineral fertilizers on leached chernozems on average for 1984-1987 increased the accumulation of dry biomass of spring durum wheat by 45.6%, and in combination with irrigation by another 57.4%. In the experiments of 2001-2003, calculated doses of mineral fertilizers increased the accumulation of dry biomass by 20.7% on the chernozems of the Transcamian region of the Republic of Tatarstan, and by 13.6% on the gray forest soils of the Pre-Kama region in 2005-2008

The results of long-term research on the influence of main indicators on their agro-resource potential are summarized on gray forest soils of the upper Volga region. For the conditions of the Vladimir Opolie, the probable yield of biomass and the main products of field crops were calculated at different coefficients ofphotosynthetic active radiation (FAR) use. Calculations of the main product yields are made taking into account the distribution of biomass to by-products and crop-root residues. For field crops of the studied crop rotations, the coefficients of precipitation utilization are estimated. They varied from 44 to 71%, depending on the crop rotation culture. On the slope of the southern exposure when cultivating winter cereals and perennial grasses, the main moisture losses were observed in the spring during snowmelt, when growing spring crops and potatoes, they were close in the autumn and spring periods. The sizes of moisture use by crops depending on the fertilizer systems for the creation of 1 C of grain units (g.u.) and from sub-arable layers are determined. In comparison with the liming background, the use of organic fertilizers reduced the water consumption coefficient from 9.6 to 8.5 mm/C g.u., their combination with a single dose of NPK - up to 7.3, and with a double dose - up to 6.8 mm / C g.u. Based on the amount of moisture used by crops, their possible yields are calculated. In spring crops, the amount of precipitation consumed (326-356 mm) corresponds to the use of 2.7-3% of the FAR and provides 54-60 C/ha of grain, in winter rye and wheat - about 4% of the FAR (yield 71-80 C/ha). In perennial grasses for 2 mowing, the moisture consumed is enough to use about 3% of the FAR., in potatoes -1.5%.

In order to obtain a higher level of crop yields in crop rotation, there is a need to increase the application of fertilizers and pesticides, which, in turn, creates environmental problems of soil and groundwater pollution by harmful chemical elements and compounds. The purpose of the study was to study the influence of fertilizer systems with different tillage systems on the accumulation of heavy metals and nitrates in the soil and the main products of field crops. Bookmarking and conducting field experiments were carried out in accordance with generally accepted methods of research. The maximum increase in grain yield from the use of N48Р18K18 on the shelf tillage system was – 0.25 (8.7%), grain units – 0.36 (9.9%), feed units – 0.41 (10.3%), digestible protein – 0.02 (5.0%) t/ha of crop rotation area. The use of N48Р18K18 in a differentiated tillage system increased grain yield by 0.34 (12.2%), grain units – 0.49 (13.5%), feed units – 1.12 (28.0%), digestible protein – 0.06 (13.6%) t/ha of crop rotation area. The use of N48Р18K18 in crop rotation with a shallow (mulching) tillage system gave an increase in grain yield by 0.38 (13.6%), grain units – 0.51 (14.2%), feed units – 0.57 (14.5%), digestible protein – 0.07 (15.9%) t/ha of crop rotation area. According to the results of research, the highest increases in mineral fertilizers in terms of productivity were characteristic of a shallow (mulching) background with a characteristic stricter nutrient regime. Our research has not found a significant increase in the content of heavy metals and nitrates in the main and by-products of field crops when applying mineral fertilizers, because their content in the products was within acceptable concentrations. The content of nitrates in the grain of different crops ranged from 18 to 40.4 mg/kg at a maximum concentration limit of 300 mg/kg. High culture of agriculture, improvement and development of new, more effective technologies of application of fertilizers in crop rotation and under each field crop taking into account soil and climatic conditions of the region, biological features of cultures and grades, specialization of crop rotations, etc. prevent environmental pollution. Rational use of mineral and organic fertilizers helps to increase soil fertility and is a major and indispensable factor in significantly increasing plant productivity and crop quality, maintaining an active biological and economic balance of nutrients without contamination of the environment with nitrates and heavy metals.

Investigations on light gray forest soils of the Chuvash Republic were carried out to study the effectiveness of the use of horn-ungulated meal or keratin as a nitrogenous organic fertilizer and zeolite-containing trefoil as a sorbent-type soil improver. The use of horn-ungulted meal as a nitrogen fertilizer of organic origin helps to enhance the biological activity of the soil. Observations during the vegetation period revealed a more intense coloration of the leaf surface, as well as an increase in the area of the assimilative surface of fodder beet and potatoes. The results of the determination of quality indicators has revealed the possibility of obtaining environmentally friendly products, as there has been a decrease in the content of nitrates in root crops fodder beet and potato tubers, increased dry matter content and sugar content in root crops fodder beet and in the tubers of potato dry matter and starch.The conducted studies have revealed the possibility of replacing the mineral form of nitrogen fertilizer with a nitrogen fertilizer of organic origin - horn-ungulated meal (keratin), which is a waste of the livestock industry. The joint application of zeolite-containing fossil meal together with horn-ungulated meal and phosphoric-potassium mineral fertilizers positively affected the increase in the use of nutrients from them not only in the row crops in the year of application, but also in the subsequent barley culture, increasing its yield and economic efficiency.

Abstract The research was carried out on the territory of the Vladimir Opolye (Suzdal, Russian Federation). For the experimental site, in the watershed part of the plakor terrain with a slope of < 1°, a soil map was compiled. Field studies were carried out in a long-term stationary field experiment measuring 86 m by 280 m with the total area of 2.41 hectares. Four tillage systems were studied in the experiment: 1. generally accepted dump-annual dump plowing; 2. combined-energy-saving-alternation of small non-fall treatments with dump plowing of perennial grasses; 3. combined-tier-alternation of small non-fall treatments with plowing with a long-line plow of perennial grasses; 4. anti-erosion-alternation of deep non-fall treatments with plowing of perennial grasses. The results showed a different reaction of soil to agrotechnological techniques. Gray forest soils with a second humus horizon have a higher potential fertility, the advantage of which when applying moderate doses of mineral fertilizers was 3.3-4.4 centners per hectare of grain units compared to the background gray forest soils. A further increase in the dose negates these differences. Deep soil loosening by 25-27 cm also shows the advantage of soils with a second humus horizon, the yield increases were 4.4-5.2 centners per hectare.

This article is devoted to the study of the effect of nitrate nitrogen content in the soil on its biological activity on crops cultivated in the system of six-field crop rotation and mono-crops, as well as the effect of nitrate nitrogen and soil bioactivity on the yield of field crops (corn for silage, peas, millet and barley) in crop rotations and mono-crops. Field experiments were carried out on a long-term plot and the results are objective from the point of view of the data on the yield of field crops, soil bioactivity and the content of nitrate nitrogen on the crops were obtained in various weather conditions, including suitable and very dry years. Very dry years are considered when the hydrothermal index is 0.6 or less, they accounted for 68% of the total number of research years. The question of the forecrop influence and the nutritional background on the field crop yield, the content of nitrate nitrogen and the biological activity of the soil is considered. The lowest biological activity of the soil is noted in the variant with permanent barley sowing on unfertilized background - 6.0 %, on fertilized background - 6.1%. As a result of the research, it was found that the yield of corn for silage is higher in mono-crops compared to crop rotation. Millet slightly reacts to application of mineral fertilizers, and when cultivated in monoculture, it reduces yield. The usage of mineral fertilizers increases the content of nitrate nitrogen and the biological activity of the soil in all variants of the experiment.
