Abstract

The changes in saturated hydraulic conductivity, macroscopic swelling and clay dispersivity of a sodic black clay soil in relation to solution concentration and Na adsorption ratio of the percolating solution were measured. Based on the threshold concentration curves, an empirical relationship relating saturated hydraulic conductivity and soil solution properties has been derived for vertisols and its field applicability established. For all practical purposes, swelling of clay seemed to be the major factor responsible for loss of saturated hydraulic conductivity of a sodic vertisol
