In most soils, continuous plowing results in the formation of a compact zone below the plowing depth. Laboratory studies were conducted to examine the effect of such a zone on the displacement of chloride (Cl-) during infiltration of water. A compact zone of 4- or 8-cm thickness of 1.62 g/cm3 or 1.80 g/cm3 bulk density was created at a depth of 8 cm in soil columns. A surface-applied slug of calcium chloride was leached with 4 or 6 cm of distilled water. The presence of a compact zone in the soil profile pushed the Cl- peak deeper, dispersed the ions in a narrower region, and increased the peak Cl- concentration. Increasing bulk density and thickness of a compact zone increased the depth of the peak Cl- concentration.
