Potassium Supplies of Main Soils in Sichuan

Huang Min Xie Jinhui (Soil And Fertilizer Institute,SAAS,Chergdu,610066 China)  
The author studied the potassium supplies of main soils in Sichuan Province by means of living things exhaustion experiment and chemical simulation test in lab.The quick available potassium and slow available potassium were the most important representatives of soil potassium supplies. Grey-brown-purple soil was the best potassium supplier in both dry land and paddy soil.The slow-available potassium could be used as the judging indicator for whether or not the soil can continually satisfy the crop,s demand for the potassium. Soils with high slow-release K level had high potential in potassium supplies.Potassium fertilizer should be applied to red-brown-purple soil especially paddy soil to supplement and maintain the K level in soil.
