Abstract

The surface chemical properties of soil samples i.e., surface charge and zeta potential, and the mineralogy of soil clay fraction were investigated with reference to soil weathering extent for 4 different soils derived from Quaternary red earth using the ion adsorption method, a micro-electrophoresis method and the X-ray diffraction analysis. Results indicated that all these soil samples, 4 ultisols collected respectively from Liuzhou, Guangxi, Changsha and Hunan Province, contained kaolinite and gibbsite. It is showed that the magnitudes of the point of zero salt effect (PZSE), the isoelectric point (IEP) and zeta potential of these soils were in agreement with the weathering extent of the soils and can be employed as reference criteria for classification and evolution of soils
