Guidance for scientific fertilization of major crops in spring of 2018 (Northeast Soybean)
Northeast soybean
(1) According to the nutrient demand of soybean, the application ratio of N-P2O5-K2O is 1:1.2:0.3-0.5 in high-fertility soil; the amount of nitrogen and potassium can be increased in low-fertility soil, and the ratio of NPK is 1 : 1:0.3~0.7.
(2) The target output is 130~150 kg/mu, nitrogen fertilizer (N) 2~3 kg/mu, phosphate fertilizer (P2O5) 2~3 kg/mu, and potassium fertilizer (K2O) 1~2 kg/mu.
(3) The target output is 150~175 kg/mu, nitrogen fertilizer (N) 3~4 kg/mu, phosphate fertilizer (P2O5) 3~4 kg/mu, and potassium fertilizer (K2O) 2~3 kg/mu.
(4) The target output is more than 175 kg/mu, nitrogen fertilizer (N) 3~4 kg/mu, phosphate fertilizer (P2O5) 4~5 kg/mu, and potassium fertilizer (K2O) 2~3 kg/mu. In low-fertility soil, the amount of nitrogen and potassium can be increased appropriately. The application amount of nitrogen, phosphorus and potassium: nitrogen fertilizer (N) 4~5 kg/mu, phosphate fertilizer (P2O5) 5~6 kg/mu, potassium fertilizer (K2O) 2~3 kg/mu.
(5) High-yield areas or soils with molybdenum and boron deficiency areas should be supplemented with boron fertilizer and molybdenum fertilizer; in areas with less severe symptoms, micro-fertilizer seed dressing can be adopted. The application of soybean rhizobium agents is advocated.
