Abstract:
Surface runoff from a deep silt loam loess soil at two exchangeable sodium percentage (ESP) values and the beneficial effect of industrial gypsum, were studied in field plots under natural rainfall conditions. The ESP of the soil was found to have a very pronounced effect on the surface runoff in spite of the fact that the final infiltration rate of the soil was affected only slightly by the ESP of the soil. The effect of ESP on the percent of surface runoff is probably through its effect on the rate of crust formation.-from Authors
