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.

Long-term observations of the drained soil of peat-podzolic-gley light loam on ancient alluvial sands state on the example of the meliorative object "Tinky-2" showed that under the influence of agricultural use in the soil, the organic matter mineralization processes are accelerated. During the drainage process, the soil evolutionarily suffered the following changes: the peat layer was compacted, humified and mineralized, which was a reason of the transformation them into the humus horizon. Based on the monitoring studies results it was established that during 21 intensive use years the peat layer thickness was decreased by 74.5% and amounted to 5.51 inch, which in the following 20 years was decreased to a layer of 1.18 inch, and for another 14 years it became a homogeneous humus horizon containing difficulty identifiable plant remains. For half a century, the bulk density increased by 6 times and the total moisture capacity of the soil decreased by 3.6 times. Other indicators were changed significantly. So, the ash content by 2016 increased from 11.2% to 52.7%. It was a reason of the plough-layer decreasing and it mixes with the mineral sand horizon during plowing. It should also be noted that the total nitrogen content in the soil decreased by 1.13%, and total carbon by 15.3% from 1982 to 2016. The dynamics of changes in the soil acidity, phosphorus and potassium content is associated with the introduction of calcareous, organic and mineral fertilizers in the 1980s. The unsystematic exploitation of such soils leads to decrease in the agricultural products productivity and increase in energy costs. When planning these soils usage in agricultural production, it is necessary to develop and implement modern melioration technologies and techniques aimed to increase soil fertility.

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%.

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.

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.

<p>The paper describes the influence of long term (more than 30 years) fertilizer application to the changes of soil properties and identifies the influence of different fertilization rates to phosphorus, potassium, calcium and magnesium accumulation in soil.</p><p>The research has been carried out at the Research Institute of Agriculture of Latvian University of Agriculture in the long-term subsurface drainage field established in Skrīveri in 1981 under the guidance of professor J. Štikāns.  The long-term drainage field was established in the uncultivated gleyic sod-podzolic <em>Hypostagnic</em> <em>Endogleyic Albeluvisol (Hypereutric), stw-ng-AB(he) </em>loam that had not been used in agriculture for 20 years before. The experimental field was established with four rates of mineral fertilizers: without fertilizers, N45P30K45; N90P60K90 N135P90K135 calculated in form of P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O. Since 1994 a seven-year crop rotation has been organized: 1) winter triticale, 2) potatoes, 3) spring wheat, 4) spring oilseed rape, 5) spring barley + perennial grasses (red clover, timothy), 6) perennial grasses, 1st year of using, and 7) perennial grasses 2nd year of using. Mineral fertilizers were applied according to the anticipated rates of plant nutrient elements annually during the cultivation of soil before sowing. For winter cultivars the phosphorus as superphosphate and potassium as potassium chloride fertilizers were cultivated before the sowing in autumn and nitrogen in form of ammonium nitrate was applied the next spring at the beginning of vegetation and at the stage of tillering. During the vegetation period all the required common agro-technical measures were taken – treatment with herbicides, fungicides and insecticides.</p><p>After 32 years of trial similar soil parameters showed significantly different content of nutrients related to the different level of fertilizer application. On a low background of fertilizers (N45P30K45) a small increase of mobile phosphorus in soil has only been observed in recent years. At the fertilizer rate N90P60K90 the content of available phosphorus and potassium in soil gradually begins to grow. Fertilization norm N135P90K135 caused a constant accumulation of nutrients in soil. In 30 years’ time the content of exchangeable phosphorus (calcium lactate – extractable) has increased more than 20 times (from 9 till 184 mg P<sub>2</sub>O<sub>5</sub> kg<sup>-1</sup>) and exchangeable potassium (calcium lactate – extractable) has increased more than 4 times (from 64 till 223 mg K<sub>2</sub>O kg<sup>-1</sup>).

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
