Influence of fertilizers and ways of processing on parameters of soil fertility at cultivation of soya

Abstract

The purpose. To study influence of fertilizers and ways of soil cultivation on maintenance of plants of soya with nutrients. Methods. Laboratory-analytical, statistical. Results. Results of researches on studying influence of fertilizers and ways of processing on nutritious mode of dark grey podzolized soil are presented at cultivation of soya. It is fixed that nitric fertilizers at different ways of entering raised the content of mineral nitrogen. Additional quantity of nitrogen on the phosphate-potash background during vegetation improved feed of plants by phosphorus and potassium. Conclusions. Nitric fertilizers on the phosphate-potash background created preconditions for increase of yield of soya concerning the control. In comparison with subsoiling the highest level of this parameter is gained at ploughing.
