“…The most qualitative selection of sideral crops is necessary to increase the efficiency of the use of the occupied fallows in field biologized crop rotations. The cultivated siderates must meet the following important requirements: have the lowest possible seeding rate to reduce the cost of buying seeds, a low transpiration coefficient in order to preserve and efficiently use the productive moisture in the soil, have an accelerated growth of biological mass so that it can be plowed into the soil as early as possible, guarantee high yields with a better quality composition [8,9,10].…”

In the arid zone of light chestnut soils of the Lower Volga region, in order to increase the influx of organic matter and basic nutrients into the soil, winter rye and yellow two-year-old clover should be cultivated in occupied fallows as sideral crops. To increase the replenishment of potassium in the soil, it is also recommended to grow phacelia on siderate as a fallow crop. Plowing oats in the form of green fertilizer led to a decrease in the input of organic matter and mineral nutrition elements into the soil compared to the control. The highest content of nitrate nitrogen, mobile phosphorus and exchangeable potassium in the arable layer of the soil during the sowing of winter wheat, when its plants leave for winter and spring regrowth, as well as during harvesting, was provided by the predecessors of the occupied fallows by winter rye, two-year-old clover and phacelia for siderate. The highest yield of winter wheat was obtained by the predecessors the pure fallow and occupied fallows by winter rye, sweet clover and phacelia for siderate. According to the predecessors, the occupied fallows by spring ginger and oats for siderate showed a significant decrease in the yield of winter wheat.

The article analyzes soil and climatic zoning of the territory of the forest-steppe of Western Siberia, population degree, contour of fields, biological economic features of crops, including the leading -spring wheat. The adaptive landscape approach to the zonal features of crop alternation was used in the work, which makes it possible to determine a reasonable ecological niche for each one, select crops in accordance with biological requirements, productivity, profitability of production, as much as possible to reduce repeated and monocrops. Monitoring of economic activity over the past 35 years has shown a tendency for commodity producers to be stratified by resource capabilities, technical equipment, and, above all, the level of agriculture intensification. In this regard, recommendations for optimizing field crop rotations are focused on expanding to 8-10 crops and adaptive varieties, considering their profitability and "soil improvement", limiting resowing, excluding continuous cultivation of agricultural crops. In conditions of limited intensive agriculture, about 5-10% of the arable land area belongs to crop rotations with winter, tilled crops, legumes, melilot, rapeseed, millet, clover, annual multicomponent grasses, the efficiency of which in terms of the yield of fodder units often surpasses grain-fallow crop rotations with short rotation. It is noted that in recent years, special attention has been paid to alternate crop rotations, which allow, with increase in farming standards and use of intensification means, to slightly reduce the fallow field and optimize the structure of arable land use, to increase the biodiversity of a set of crops and adaptive varieties. The tendency to switch to rotation crop, among commodity producers of a more humidified forest-steppe zone, is possible only with the use of fertilizers and the improvement of agrophytocenoses. The expansion of alternate crop rotations and the reduction of repeated sowing of spring wheat is also due to positive changes in hydrothermal conditions in arid soil and climatic zones of Western Siberia.
