Changes in the saturated hydraulic conductivity (K) of undisturbed, sand and loamy sand soil columns were monitored in the laboratory. Each soil column was treated to four cycles, each cycle consisting of irrigating from below with water of specified salinity, followed by leaching by ponding fresh water on the column tops. During any one leaching phase, K decreased by 57 to 98 percent. Yet, K rebounded to initial levels during any subsequent subsurface irrigation phase. Leaching times varied greatly (2.2 to 187 days) but required a depth of leaching water of only 0.4 to 0.7 of the soil depth to reduce the leachate salinity by 80 percent.
