Abstract
The purpose. To optimize norms of fertilizers for predicted productivity of soya bean at the level of 3 — 4 t/hectare. Methods. Balance method of removal of nutrients with predicted yield and their return to soil in view of biological nitrogen. Results. Optimum norms of fertilizers for predicted productivity of soya bean are calculated: 3; 3,6; and 4 t/hectare. Conclusions. Assortment of fertilizers for soya bean, as well as forms, time and methods of their application are specified.
