Abstract
Using nondestructive measurements the simultaneous transport of chloride and water was examined for infiltration and redistribution within laboratory soil columns. Chloride, either spread on the soil surface or initially dispersed throughout the soil to simulate a salt-affected soil, was leached with chloride-free water (0.01 N CaSO4). Water application methods yielding small average soil water contents during infiltration leached the chloride efficiently and to relatively greater depths. Although the initial soil water content prior to leaching did not have any appreciable effect on leaching during infiltration, the smaller the initial soil water content, the deeper and more complete was the displacement of chloride during redistribution for a given quantity of water applied.
