| Abstract: | The suitable amounts of potassium fertilizer for soybean were studied in albic soil in Yushu, Jilin. The result indicated that the suitable application amount of potassium in plot experiment was K2O 40.05 - 60 kg/hm^2. The demonstration experiments applied K2O 0.05 kg/hm^2, the soybean production increased 125.25 kg/hm^2, about 9.4% in average, additional incomes were 306 yuan/hm^2. |
