The velocity of the nonexchangeable potassium release from the soil tested is different at different stages of time.The velocity of the nonexchangeable potassium release is more highly marked in 0～72 hours than in 72～912 hours.

非交换钾释放是粘土矿物层间钾缓慢扩散进入液相的过程，释放速率决定着土壤供钾能力，非交换钾释放动力学性质在土壤供钾能力评价中有着更为重要的作用。

The process of the nonexchangeable potassium release from the soil tested in 912 hours can be well described with linear equation.④ The constant B rate of the nonexchangeable potassium release from the soil tested is controlled by the content of clay and slowly available K.

关于非交换钾的释放动力学，Martin等已用几种微酸性砂质土和砂壤质土进行了初步研究［7～10］，国内在此领域研究不多，对中国北方广泛分布的黄土性土壤非交换钾释放动力学研究更少。
