摘要

The aim of this paperis to determine the kinetics relation between fixation and release of K,when different doses of fertilizer have been added to a soil with a low potassium content.Chemical determination of coefficient rate "B",residual parameter and Q/I isotherms tostudy the relation between capacity and intensity of K,showed that there are three pools of K;solulbe K,exchangeable K and residual K.The first dose of fertilizer added to the soil satisfies the residual K and covers only few spaces of the soluble K.The second dose of the fertilizer is proportinally distributed between the soluble,exchangeable and residual forms.There was a relationship between added and residual potassium.
