The aim of the research was to determine the optimal dose of phosphate fertilizers on the background of the use of nitrogen-potassium fertilizers in the potato cultivation of the middle-early group of Nevskiy variety. Experiments were carried out on gray forest soil of medium loamy granulometric composition with humus content in the arable layer according to Tyurin - 3.22-3.31%, easily hydrolyzed nitrogen - 140-155 mg/kg of soil, mobile phosphorus - 142-147 mg/kg, exchangeable potassium - 138-151 kg/kg of soil. Nitrogen-potassium background and sulfur in a dose of N90K120S30 were used in the experiments. Phosphate fertilizers were applied, depending on the variant, in increasing doses - P30, P60, P90, P120 kg of active substance. The results of studies on the effect of increasing doses of phosphate fertilizers on the productivity and quality of potato tubers of Nevskiy middle-aged group of ripeness are presented. Analysis of the content’s dynamics of the mobile phosphorus in the irrigated experimental plot of gray forest soil showed that it has a good provision with a mobile form of P2O5. During the growing season on fertilized variants, its content increased with increasing dose of phosphorus and varied in the soil phase of plant development. In the process of research, it was found that fertilizers in a dose of N90K120S30 (background) increased the crop of potato tubers by an average of 4 years by 9.54 tons per hectare. Phosphate fertilizers applied in addition to the background (N90K120S30) as their dose increases from 30 to 120 kg of active substance provided an increase in yield by 1.27-6.34 tons per hectare. The main elements of the mineral nutrition of plants in different ways influenced the quality of potato tubers. The introduction of phosphate fertilizers contributed to an increase in the content of dry matter, starch and improvement in taste in tubers, while the amount of nitrates decreased. Based on the data obtained, it can be concluded that in order to improve the quality indicators of tubers, a dose of fertilizers should be applied - N90P120 K120S30.

An application of calculated doses of fertilizer for potatoes in the gray forest soil of medium-size distribution, on average for 4 years, provided a receipt of planned crop of 25-35 tons per hectare and 94% of planned harvest in the background of 40 tons of tubers per hectare. Thus at higher fertilizer backgrounds, calculated to harvest 35-40 tons tubers per hectare, the starch content decreased and its harvest increased 2.22-2.33 times. The maximum permissible concentration of nitrate in potato tubers does not exceed.

In modern conditions, one of the priority directions of potato growing is the selection of new highly productive varieties, resistant to the action of abiotic and biotic factors. When potatoes are cultivated, the optimization of mineral nutrition and the depth of planting of seed tubers is an important factor for obtaining sustainable yields. The experiments were laid on gray forest medium loamy granulometric composition of the soil of the forest steppe of the middle Volga region. It was established that the highest yield - 52.50 tons per hectare was formed when fertilizer doses (manure 50 tons per hectare + N135-153P135-145K179-184) were calculated for 50 tons per hectare of tubers, when planting to a depth of 8-10 cm. On tte background fertilization in a dose of manure 50 tons per hectare + N120P120K140 when planting at the same depth yield was 49.50 tons per hectare. On the variant with a planting to a depth of 6-8 cm, the yield of tubers was to 2.89 and 2.92 tons per hectare lower.

The aim of the research was to study the effectiveness of an application of increasing doses of potash fertilizers in the potatoes cultivation of the middle-early ripeness group of Gala variety on the background of the use of nitrogen-phosphorus fertilizers and sulfur in the dose of N90Р120S30. Studies were carried out in 2016-2018. The soil of the experimental site of gray forest medium loamy granulometric composition had the following agrochemical characteristics: pH of salt extract - 5.4-5.7; humus content - 3.28-3.41%; easily hydrolyzed nitrogen - 146-160 mg per kg; mobile phosphorus - 140-152, exchangeable potassium - 146-160 mg per kg of soil. Potassium fertilizers were applied in increasing doses - К30, К60, К90, К120, К150, К180 kg of the active substance together with the background fertilizers - N90Р120S30 and microelements deficient in this soil: copper, boron and molybdenum in the composition of ZhUSS-1 and ZhUSS-2. The influence of the studied doses of fertilizers on crop yield, dry matter content, vitamin C, starch and nitrates has been established. On average of three years, the productivity of tubers was 21.67 tons per hectare. When applying background fertilizers (N90Р120S30) compared with the control, it increased by 4.32 tons per hectare. The optimal dose of potash fertilizer on the background of N90Р120S30 for potatoes grown under irrigation was К150, where the average yield of three years was 34.42 tons per hectare. A further increase in the dose of fertilizers did not significantly increase the productivity. On average of three years, the highest dry matter content was 22.81% and starch - 13.15% was noted in the variant, where potassium was applied in a dose of К180 kg of the active substance together with background fertilizers and microelements. With the introduction of high doses of potassium (К150 and К180 kg of the active substance), the content of dry matter and starch did not significantly differ from those in the control.

The reaction of new early ripening potatoes of Molly, Red Scarlett and Kolette varieties on the main processing of gray forest soil in the conditions of the forest steppe of the Middle Volga region was studied. The aim of the work is to determine the effectiveness of different soil treatment options. The work was performed on the experimental field of Kazan SAU in 2012-2015. The dumping of plowing at a depth of 20-22 cm was compared with a non-spinning loosening of 26-28 cm and processing of a BDP by 18-20 cm. It was established in the course of research that, without spilling, Molly’s variety, on an average for four years, yielded 36.29 tons per hectare, with the dumping of plowing 35.89 tons per hectare. In similar variants, Red Scarlett formed the yields of 38.66 and 37.96 tons per hectare, and the grade of Kolette - 34.29 and 35.84 tons per hectare. With all methods of soil treatment, more starch contained potato tubers of the Kolette variety. Depending on the variant of soil cultivation, it was 13.73-14.13% in tubers of this variety. Less starch (12.83-13.20%) contained tubers of the Molly variety. Vitamin C and protein was more contained in the tubers of the Red Scarlett variety.

Research was conducted to study the reaction of early varieties of Bellarosa potato to the application of calculated fertilizer doses and planting density in the conditions of the forest steppe of the Middle Volga region. Experiments were laid in 2012-2015 on gray forest soil of medium loamy granulometric composition, on the experimental field of the Transcaucasian Republic of Tatarstan. The article presents the results of 4 summer studies. It was established that the average yield for the 4 years was 41.17 tons per hectare, with a planting density of 66.6 thousand tubers against the background of nutrition, calculated to produce 40 tons per hectare. The introduction of calculated fertilizer doses for a potato yield of 30 tons per hectare, depending on the planting density, increased the productivity of tubers to 8.17-10.96 tons per hectare. The highest yield against this background – 31.18 tons per hectare on average for 4 years was formed at a density of planting 66,6 thousand pieces per hectare. It should be noted that the introduction of calculated fertilizers at this yield level increased the efficiency of increasing the density of planting, where the yield increase from this intake was 4.22 and 5.81 tons per hectare. The effectiveness of increasing the density of planting with a further increase in the background of nutrition was not so high. So, against the background of fertilizers calculated for yield of 35 tons per hectare, the increase from the increase in the density of planting to 60.6 and 66.6 thousand, compared to 55.5 thousand pieces per hectare, was 1.62 and 2.62 tons per hectare. Against the background, calculated for harvesting 40 tons per hectare on average over 4 years, an additional 1.60 and 2.90 tons per hectare of tubers were obtained.

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.

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.

The content of mineral nitrogen was studied when it was applied at a dose of 60 kg / ha on gray forest soil of heavy particle- size distribution at various levels of phosphorus-potassium nutrition in field experiments with barley. Fertilizer doses were determined by the normative method according to the CINAS method for a planned yield of 3 t / ha. It was shown that the dynamics of nitrate and ammonium nitrogen depended on the moisture regime during the vegetation period. With excessive moisture, nitrate nitrogen, with its initial content of 4-5 mg / kg, is not detected in the arable layer by the middle of the growing season, and with a moisture deficit, less dynamism is noted. It is found in an amount of 5-7 mg / kg by the end of vegetation. The N – NH4 + dynamics turned out to be less pronounced. With an excess of moisture, its content increased to 15.6 mg / kg, and with a deficit, it decreased more than by four times from the maximum during the vegetation. In general, the content of mineral nitrogen in gray forest soil is highly dynamic, which depends on the moisture regime and the nature of its consumption by barley.

The studies were carried out to determine the effectiveness of applying calculated doses of fertilizers to the planned potato tuber yields of the early-ripening Molly and Colette group in the conditions of the forest steppe of the middle Volga region. The influence of mineral nutrition backgrounds, calculated on obtaining tuber yields of 25, 35 and 45 tons per hectare in comparison with the unapproved control, has been studied. The analysis of the leaf area dynamics of potato plants, the parameters of the leaf photosynthetic potential, the coefficient of photosynthetically active radiation factor showed that these indicators of photosynthetic activity are directly dependent on the level of mineral nutrition. Against the background of natural fertility, the Molly variety produced 16.76 tons of tubers per hectare and 18.32 tons of the Colette variety. Fertilizers, calculated for 25-45 tons of tubers per hectare, ensured the formation of Molly 28.23-43.57 t ons per hectare, Colette - 29.72-42.54 tons per hectare. The introduction of calculated doses of fertilizers at 25 and 35 tons of tubers per hectare did not result in a significant decrease in the starch content in the tubers, and the doses that were calculated for a yield of 45 tons per hectare increased the amount of nitrates and reduced the starch content in the tubers.
