Detachment Rate in Cropland and Pasture Soils

摘要

Soils samples of different texture (silty loam, silty clay loam and clay loam) and land use ranking from pasture to Conventional Tillage (CT) and No tillage (NT) were exposed to rain of 55 mm · h~(-1) (1,350 J · m~(-2)) with a rain simulator in order to analyze the relationship between soil parameters and detachment rate (Di). It was observed that the use of some equations could have unbiass to predict soil erosion because the relationship between selected parameter are no linear. The interaction between drop impact and soil stability should be considerate because could modify the detachment rate a despite of soil texture.
