Quantitative assessment of soil erodibility on the ameliorated lands in Georgia

The erodibility of ameliorated lands in administrative regions of Georgia has been estimated. A Universal Soil Loss Equation modified at the Problem Laboratory of Soil Erosion and Channel Processes of Moscow State University has been used to predict the soil loss. The erodible ameliorated lands of Georgia are specified into three categories: slightly erodible (19% or 304 000 ha), moderately erodible (5% or 80 000 ha), and strongly erodible (76% or 1 194 000 ha). About 510 000 ha of ameliorated lands in Georgia are subjected to wind erosion of different intensities: slight (43% or 220 000 ha), moderate (44% or 224 000 ha), and high (13% or 66 000 ha). The ameliorated lands of Georgia also include 184 000 ha of potentially erodible irrigated lands specified into slightly erodible (91% or 167 000 ha) and moderately erodible (9% or 17 000 ha). Areas with highly erodible irrigated soils have not been revealed.
