Assessment of the Actual Risk of Sheet Water Erosion of Soil for the Territory of Krushari Community
Keywords:
USLE, C-factor, actual erosion risk, sheet water erosionAbstract
Assessment of the actual risk of sheet water erosion using a predictive model is a basic step in optimization of soil conservation measures. Predicted actual soil erosion risk is based on potential soil erosion risk assessments and indices characterising the soil protection capability of plants.
The methodology of the Universal Soil Loss Equation (USLE) was applied for the territory of Krushari community, Dobrich region, in order to assess the actual risk from sheet water erosion. The results obtained show that the share of land with soil erosion risk exceeding the tolerable soil loss which need implementation of measures for soil erosion control takes 2 to 7% of the area of arable lands depending on the type of crops and farming manner.
