Soil organic carbon (OC) was studied at 4 sites, native and cultivated. At the native site aspect had the greatest influence on OC levels. At the cultivated site OC distribution is due to water and tillage erosion. All topsoil had been eroded from south slopes. Perennial grass rotations had added OC above and below the surface while reducing OC loss from erosion and oxidation. Strip cropping and uphill plowing resulted in a greater depth of OC. T: Average surface organic carbon values by slope position.
