Different crops and crop rotations with a different crop structure have a different influence on biological interchange of the matter. Depending on the crops and their balance, removal and return of nutrients change greatly. That is why while developing specialized crop rotations it's necessary to take into account their agrotechnical evaluation along with the economic one. Nitrogen status is one of their elements. The results of 24 year researches in the stationary experiment on the study of nitrogen balance in different types of crop rotations are discussed in the paper. The values of the accumulation of biological nitrogen in soil due to fixation through the air in crop rotations with leguminous and leguminous-cereal grasses were determined. Soil nitrogen balance, as well as economic one, is largely dependent on the type of crop rotation.
