These soils contain mainly kaolinite gibbsite and goethite which are described as variable charge colloids. The net surface charge of these soils is low. Liming soils with variable charge colloids increases the net surface charge. Lime requirement of the soil can be estimated from buffer curve. Below pH 5.5 the buffering action of these soils is controlled by aluminium (A1). But above pH 5.5 clays control the buffering action. Of the clay minerals present in the soil kaolinite seems to be the dominant buffering substance

Abstract

These soils contain mainly kaolinite gibbsite and goethite which are described as variable charge colloids. The net surface charge of these soils is low. Liming soils with variable charge colloids increases the net surface charge. Lime requirement of the soil can be estimated from buffer curve. Below pH 5.5 the buffering action of these soils is controlled by aluminium (A1). But above pH 5.5 clays control the buffering action. Of the clay minerals present in the soil kaolinite seems to be the dominant buffering substance
