dc.description.abstract The effects of intermittent ponding on salt movement through a saline-sodic clay soil were investigated by adding varying total amounts of water (16 and 32 cm) at different irrigation intervals (5, 10 and 20 days). The soil columns were subjected to a potential evaporation rate of 0.48 cm•day-.. The application of water resulted in the formation of a desalinized zone underlain by a salt accumulation zone. The highest salt concentrations coincided with the wetting front. Salt leaching was more efficient with large and less frequent applications. A modified Versatile Soil Moisture Budget, which incorporated soluble salt mixing concepts as advanced by Burns (1974) showed satisfactory agreement between measured and predicted salt redistribution profiles. Discrepancies, which occurred toward the end of the experiment, were believed to be related to the assumption that salt diffusion could be neglected. en_US
