Abstract:
This study was conducted to determine the effects of absorbed Mg in erosion of soils exposed to rain. The effects of adsorbed Mg and Ca in soil erosion and infiltration rate (IR) of two soils (a Calcic Haploxeralf and a Typic Rhodoxeralf) exposed to rainfall, in the absence and presence of adsorbed Na, was studied. The erosion rate of the soils was higher for the Mg-soils than for the Ca-soils. It was suggested that the steady-state infiltration and soil erosion rates are the result of two processes that occur in opposite directions: seal formation and soil detachment. -from Author
