%X The K supplying capability and characteristics of five conventional organic fertilizers,e.g..cattle manure,pig manure,chicken manure,crop residue and green manure,are studied.The results show that the fertilizer K which is converted into rapidly available K of soil reaches a balance about 30 days of culturing in soil,but the fertilizer K which is converted to slowly available K of soil tends to steadiness after 70 days.The transformation rates of the available K of fertilizers in soil are about 50 % ~ 87 %,and those of the slowly available K are about 50 % ~ 80 %.In different K sources,the K supplying capability of wheat straw is higher than that of K fertilizer,but that of three manures is lower than that of fertilizer K.The K supplying capability of organic fertilizer is related to soil types and soil environments.
