文摘The results from comparative study of the EUF-K values of four different soils and of their varions particlefractions (<2μm, 2-10μm and 10 50μm) showed that the EUF-K values were related to the composition ofclay minerals and the soil particle size. The EUF-K values (0-35 min) were closely related to the amountof rapidly available K and part of non-exchangeable K of soils. Biological experiments proved that EUFtechnique was an effective method for evaluating soil K-supplying power.
