P Adsorption and Desorption of Three Patly Soils

Song Yu-zhi

Abstract

A experiment of phosphate adsorption and desorption isotherm for three paddy soils was conducted.The results showed that the curves of practically measured phosphate adsorption and desorption were identical with the simple Langmuir equation,and the correlation coefficients of all samples were significant at 0.01 probality level.The content of physical clay affected the maximum quantity of phosphate adsorption greatly,but had no effect on phosphate desorption.
