| Abstract: | In order to investigate the variety of available potassium accumulation under immobile fertilization, a mathematical model which take available potassium accumulation of soil in the blackland of Songnen plain, manure, fertilizer and straw as experiment factors was established. The results showed if keep the accumulation of available potassium in 230~270 mg/kg, the employ of manure, fertilizer, straw in five years should be 832~1120 kg, 34~947.8 kg, 93~122 kg in every 667 m2. |
| Keywords: | manure fertilizer straw available K mathematical model |
