Soybean productivity depending on the level of nutrition in Primorie

Influence of mineral, organic and mineral-organic fertilizers applied to the liming soil on soybean productivity in long-term crop rotation experiment is studied. The most highly productive agricultural-ecological system is formed when full mineral fertilizer is combined with periodical liming and organic fertilizer applied into soil for a long period of time. Such system can exceed the usual one on soybean productivity on 37 % in years with favorable conditions. This method provides a high content of nutrients in soil and excludes necessity to apply mineral fertilizers under soybean annually.
