随着土壤含水量增加,水溶性钾在土壤中的扩散强度有明显提高,0.3巴含水量与0.8巴含水量相比,钾扩散系数提高4.3倍.

• This will improve available K in the soil. 4 ) K diffusion coefficient increased with the increase of soil water content. In comparing 0.8 with 0.3 bar soil water content, the K diffusion coefficient increased from 0.56 to 2.4 ( cm/s 10);
