Based on the data of multi-year research (1964 2018), the article gives ecological and economic estimation of crop rotation and pasture rotation affected by agrotechnical and agroforestal activities in the steppe and dry steppe of the Volga region. The agrotechnical technique of soil-slotting with mulching increased the profitability of crop and pasture rotation by 22.2%, compared with controlling. Conducting the complex of anti-erosion measures restores the functions of the soil cover, which results in the increased productivity of agricultural crops and grasses, and consequently, in the increased profitability of the applied agrotechnical and agroforestal techniques. According to regression and correlation analysis, profitability is by 48% related to the productivity of agricultural land and costs of crop and grasses production. Soil-slotting with mulching increases soil fertility, land productivity and profitability.
