| Abstract: | Based on several severe phenomena of aimless fertilization on soybeans in Keshan County,the optimal fertilization on yield and benefit in soybean was investigated.Optimal fertilization stimulated growth,development and yield of soybean in black soil of Keshan.Compared with the optimal fertilization,yield reduction was 24.8%,26.7%,15.9%,26.0% and 16.0% in treatments of no nitrogenous fertilizer application,no phosphate,no potash,no chemical fertilizers,and farmers'conventional fertilization respectively. |
