There were worked out the recommendations on growing of crops in short-term rotations to save soil fertility in them. More effective was a grain-fallow-tilled crop rotation with a saturation of soybean 20%, ensured a conditionally net income at the level of 6932-10889 UAH/ha, and organic-and-mineral system of fertilizing helped to increase a productivity of crop rotations, that ensured a growth of profitability on 518-750 UAH/ha. The use of microbial preparations contributed to the growth of indicators of economic efficiency in grain-fallow-tilled and grain-tilled rotations for all fertilizing systems, and a higher additional conditionally net income of this agro measure was 732-1181 UAH/ha on the background of the natural fertility of soil and 1009 -1147 UAH/ha for the organic-and-mineral system of fertilizing Product Description popup.authors Ковальова К.І.
