Drainage Rate

This dataset contains the soils: hydrological attributes in South Africa. Crop yield and hydrological models require soils information such as thicknesses of the various horizons modeled, soil water contents at critical retention levels and the erodibility of the soil for input. These variables have been derived for all soil series identified in South Africa via the AUTOSOILS decision support tool and their attributes are area averaged at the level of Land types for purposes of mapping.
