In a long-term places, located on the experimental fields of Siberian Research Institute of Agriculture (Omsk), the schemes of field crop rotations were modernized by introducing oil crops (rapeseed, soybean) into rotation and replacing the repeated wheat crops with barley and oats. Accounting of grain crops productivity and accompanying observations were carried out in three field rotations of different lengths of rotation (four- and five-field) and on permanent sowing. The repetition of the experiments is fourfold. The system of agrotechnical measures recommended for the zone of the forest-steppe of Western Siberia was applied. The study of predecessors in the cultivation of crops for various purposes was carried out in field experiments using conventional methods. The humus content for rotation in the soil layer of 0-40 cm increased by 0.19% in the crop rotation “rapeseed - wheat spring wheat - barley - soybean - spring wheat”. The largest accumulation of humus (0.83%) was in the rotation “soybean - spring wheat - barley – oats”. During the years of research wheat productivity varied from 0.82 to 2.22 tons per hectare. Wheat was the first crop in all its predecessors to form grains, on average, by 0.3-0.5 tons per hectare, than the second crop. The yield of soybeans in the crop rotation was 1.23-1.78 tons per hectare. The productivity of rapeseed was low, its productivity over the years was 1.31 tons per hectare. Grain-fodder crops (barley, oats) averaged 0.4-0.6 tons per hectare, higher than the spring wheat productivity in the alternating rotation. The maximum yield of grain from a hectare of arable land was noted in the crop-steam rotation and amounted to 1.7 tons. An increase in the yield of feed-protein units was observed in crop rotations saturated with oil crops (rapeseed and soybean) and amounted to 3.4-4.0 tons per hectare. The economic calculation showed that the cultivation of field crops in the rotational crop rotation of “soybean - wheat - barley – oats” increased profitability by 44%, net income - by half, in comparison with the control variant. The obtained materials can be used to develop schemes of field crop rotations for the zone of the forest-steppe of Western Siberia.

The long-term research conducted in 2002-2017 in a long stationary experiment on studying different types of field crop rotations under conditions of the Kirov region showed that on sod-podzolic soils the loss of humus could be lowered using agro technical methods. The most critical of them include the reduction of a portion of bare fallow, transition to sown and green-manure fallow, expanded use of perennial legume and grain-legume crops and intercrop sowings. In eight-field crop rotations when using such means of a biologization as plowing of the root-stubble residues, aboveground mass of green-manure crops in fallow fields and intercrop sowings, the supply of organic substance was within 17.24-83.03 t/ha. By mineral-ization of this substance 7.64-11.51 t of humus were produced. In a crop rotation with bare fallow there is a negative balance of humus of -0.06 t/ha. The positive balance is obtained when using sown, green-manure fallows, intercrop sowings (two-three fields), and introduction of up to 25% perennial legumes to the structure of crop rotations. The formation of 0.96-1.44 t/ha of humus in the arable layer provides positive balance of 0.20-0.72 t/ha. The increase of the part of grain crops up to 62.5-75.0% in the structure of crop rotations resulted in rise of their efficiency up to 4.74-4.79 thousand fodder units. It was 0.27-0.32 thousand fodder units higher than in the control crop rotation with bare fallow. Dependence of productivity of agricultural crops on humus content was insignificantly negative (r = -0.16). The efficiency of the studied crop rotations depended considerably on the amount of productive moisture in the soil in a phase of ear formation of grain crops (r = -0.78) and on biological activity of the soil (r = -0.80).

Field experiments were carried out in the Rostov region on the slope of ordinary chernozems in the system of contour-strip organization of the territory in 2011-2020. The aim of the research was the development of agrotechnical methods (design of crop rotation, the method of basic tillage and the background of fertilizers), which ensure high productivity of crop rotations on the eroded slope of ordinary chernozems and the preservation of fertility. The experiment included three factors: the design of the crop rotation, the method of the main tillage, the background of mineral fertilizers. It was found that, on average, for the period of research, the level of mineral nutrition has the greatest influence on the productivity of the crop rotation (83.9%), followed by the design of the crop rotation (14.9%). The influence of basic tillage is estimated at only 1.2%. It was found that the introduction of 20% of perennial grasses into the structure of crop rotation reduces soil washout by 19.5-27.7%, and an increase in the proportion of perennial grasses to 40% by 38.3-43.8%. The use of chisel tillage reduces washout by 15.6-24.2%, and with it the loss of humus. In the “C” crop rotation in all variants of the experiment, the humus content increased by 0.010.03%. It was revealed that the productivity of all the studied crop rotations changed under the influence of agrotechnical methods, reaching in the crop rotation “C” with 40% of perennial grasses and 60% of grain crops on average for the studied period the highest value of 3.53 t / ha of grain units, which is 9.3% higher than in the “B” crop rotation and 17.3% higher than in the “A” crop rotation.

Results of researches of efficiency in short crop rotation with busy steam are given in this article. Researches were conducted in the Omsk district of the Omsk region on typical black soil, with the maintenance of humus of 6.7% (in a layer of earth of 0-30 cm).  Cultivation of field cultures against the background of application of means of chemicalixation was carried out in a crop rotation the occupied steam (green manure) – wheat – barley – oats. During the conducted researches the quantity and dynamics of moisture, the maintenance of the main macrocells in the soil, and efficiency of all crop rotation was defined. The received results allow to draw a conclusion that in a crop rotation with busy steam and four fields at application of means of chemicalixation the increase of a harvest of the first wheat for 45.2%, barley repeatedly 31.5% and oats for 9.9% is noted. Application of fertilizers, at the rate of N30P30 on 1 hectare of an arable land, and herbicides, provided increase in productivity grain on 0.53 t/hectare, an exit of grain of 0.44 t/hectare, and feed-protein units to 1.29 t/hectare. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia.

Cultivation Technology

Spring bread wheat is cultivated in the Omsk region, mainly in grain-fallow crop rotations, repeated and perma[1]nent crops, less in crop-changing rotations and occupies up to 73% of the grain share of Western Siberia. Soybean crops are growing in the region, but at the same time, there have not been sufficiently studied the peculiarities of the cultivation technology of spring wheat sown after this forecrop. The purpose of the current study was to establish the efficiency of agricultural cultivation technologies of spring wheat in the crop rotation sown after soybean in the southern forest-steppe of Western Siberia. The study was carried out in a stationary crop rotation with alternating crops (soy[1]beans – spring wheat – oil flax – barley) in the laboratory for resource-saving agricultural technologies of the Omsk Research Center on meadow-blackearth soil in 2011–2019. There has been established that the soil cultivation system and the means of intensification influenced the elements of fertility and the phytosanitary state of the agrophytocenosis of spring wheat sown after soybean. With subsurface plowing, in comparison with moldboard plowing, there was an increase in biomass and number of weeds on 21 and 43%, respectively. The use of chemicals resulted in a significant increase in spring wheat biomass (on 1.8 times) and a decrease in number of weeds (on 3.3 times), which had a noticeable effect on the productivity. Productivity of wheat sown after soybeans decreased with a decrease in tillage intensity from moldboard plowing to subsurface plowing on 16%. The intensive cultivation technology of spring wheat increased its productivity up to 3.32 t / ha, the protein and gluten content in grain on 16–18%. As for chemicals, the maximum grain number increase on 28.2% was provided by the use of fungicides compared to the control (1.46 t/ha).

Research on the effectiveness biomodified mineral fertilizers were carried out on the basis of Ulyanovsk SRIA – SamSC RAS branch during the rotation grain fallow five fields crop rotation: pure steam – winter wheat – spring wheat – barley – oats in 2013-2018. The field experiment scheme included options (except control): with the introduction of biologics BisolbiFit (introduction with seeds that were treated before sowing), azofoski N15P15K15, in pure form, modified with biopreparation azofoski in the same dose N15P15K15, half a dose of modified azofoski (N7, 5 P7, 5 K7, 5). The effectiveness of fertilizers and biopreparations in crop cultivation was studied on three backgrounds: natural (control), ammonium nitrate at a dose of 40 kg ai/ha (NH4NO3), and modified ammonium nitrate at a dose of 20 kg DW/ha. It was established that modification of azofoski with Bisolbifit biopreparation can significantly increase the coefficients of use of elements from it by plants. The latter allows to reduce the dose of fertilizer, without reducing the productivity of cultivated crops, twice. Long-term cultivation of crops using only mineral fertilizers and biological products led to a relative decrease in the humus content in the soil and its acidification. For 6 years, the content of humus in the arable layer of leached chernozem decreased by 0.12 %, and the acidity of the soil solution increased by 0.5 pHKCI units. In the conditions of the Volga forest-steppe, when cultivated on chernozems, the highest-yielding winter wheat is (up to 4.00 t / ha or more, in our experiments 3.88-4.80 t / ha). The average yield of spring wheat was 2.68-3.31 t / ha, spring barley 2.67-3.21 t / ha, oats 2.15-2.71 t / ha. The highest productivity of crop rotation was observed against a background with modified ammonium nitrate at a dose of 20 kg ai/ha (½NH4NO3) when applying modified azofoski (N15P15K15). Grain harvest for 2013-2018 in this variant was 13.36 t / ha, exceeding the control variant on this background by 1.31 t / ha.

The aim of the research is to take a comparative assessment of the amount of plowed down plant residues in various field crop rotations in the conditions of the Republic of Mari El. The study was carried out in 2013-2018 on a stationary site in a two-factor experiment. Factor A ‒ types of crop rotations and shift of crops: 1. Grain and grass crop rotation (oats + clover, clover of the 1st year of use (y.u.) for green mass, winter rye, vetch and oat mixture for grain, spring wheat, barley. 2. I fruit-changing crop rotation (vetch and oat mix for green fodder, winter rye, barley, potato, vetch and oat mixture for grain, spring wheat). 3. II fruit-changing crop rotation (vetch and oat mixture for grain, spring wheat, potato with manure (80 t/ha), barley + clover, clover of the 1st year of use for green mass, winter rye). 4. III fruit-changing crop rotation (barley + clover, clover of the 1st year of use for green mass, clover of the 2nd year of use for green mass, winter rye, potato, oats). Factor B ‒ mineral fertilizers: 1. Without fertilizers. 2. N60P60K60. In the control grain and grass crop rotation with a oneyear use of clover, 3.02±0.06 t/ha of crop-root residues were received per year on the average. In the I fruit-changing crop rotation, due to the replacement of clover with potato, residues formed 2.14±0.04 t/ha, which was significantly less than the control variant (LSD05 in factor А ‒ 0.21). In the II fruit-changing crop rotation, the accumulation of crop-root residues amounted to 2.91±0.07 t/ha. Compared to the control, it was within the limits of experimental error. The largest number of crop-root residues was accumulated in the III fruit-changing crop rotation (3.37±0.07 t/ha). The use of mineral fertilizers significantly increased the bulk of crop-root residues in all crop rotations by 0.16 t/ha per year on the average (LSD05 in factor B ‒ 0.15). Carbon to nitrogen ratio (C:N) in the crop-root residues of clover and potato was 18…20, in the vetch-oat mixture it was 25…31, in spring grain crops it was 39…41, and in winter rye it was 53.

Abstract. The purpose of the study was to study the influence of biologized crop rotation with six fields by 50 %, saturated with legumes, on soil fertility and crop productivity on typical sod-podzolic light loamy soils of the Upper Volga. As a result of field experiments and laboratory studies, new data and knowledge about the effect of crop bipolarization on its productivity and the properties of sod-podzolic soil were obtained. For the first time in the region, it has been studied and established that use of legumes in the crop rotation instead of organic fertilizers partially contributes to the replenishment of the soil with organic matter and nitrogen in the form of organic residues and nodule bacteria, which leads to a decrease in the degradation of soil fertility or even to some improvement. By the end of rotation of the crop rotation when applying (NPK) 90 kg/ha compared with the control version (without NPK), in the biologized crop rotation, the humus content increased by 0.14 %, the acidity of the soil solution slightly decreased by 0.25 units, the content of nitrate nitrogen increased by 59 %, mobile phosphorus – by 72.8 % and exchange potassium – by 70.4 %. The density of soil compaction as a whole in a layer of 0–20 cm in occupied steam, under spring wheat and oats amounted to 1.22–1.24 g/cm3, in other crops (where treatment was not carried out for 2 years) – 1.35–1.39 g/cm3. Mineralization of flax tissue more actively occurred under clover 1st and 2nd years of use – 35.6–42.7 % and 31.0 and 37.3 % and in the employed (vetch-oat) – 26.5–34.4 %, less intensively under winter wheat – 20.9–27.5 and oats – 20.1–25.2 % and very weakly under spring wheat – 13.0–16.5 % at the control and the level of mineral nutrition, respectively. There were fewer weeds in winter wheat sowings – 84 pcs/m2, since it is more competitive with them, oats – 112 pcs, clover – 131 pcs, in a couple – 124 pcs and spring wheat – 138 pcs/m2. Productivity of crops to a greater extent was determined by the applied fertilizers. In fertilized plots, compared with the control, the productivity of the oatmeal mixture was 36.2 % higher, spring wheat – 24.4 %, clover 1st year of use – by 36.2 %, 2nd year of use – by 45.7 %, winter wheat – by 25.7 % and oats – by 30 %.
