Abstract


Soil erosion is a global threat to the natural resources and is particularly responsible for reduction in crop yield due to reduction in land productivity and storage capacity of multipurpose reservoirs due to continuous siltation (Rupesh Jayaram Patil, 2018). Soil erosion is process of soil loss. Particularly from the surface, but sometimes a large mass of soil may be lost, as in landslides and riverbank erosion. Soil erosion processes are mainly caused by two mechanisms: raindrop impact and surfacewash resulting fromwater in excess of infiltration (Ellison, 1947). Soil erosion is determined by a number of factors such as: relief, climate, soil and solidification rock, vegetation. Soil erosion is a natural process, occurring over geological time, and most concerns about erosion are related to accelerated erosion, where the natural rate has been significantly increased by human activity. Soil erosion poses severe limitations to sustainable agricultural land use, as it reduces on-farm soil productivity and causes the accumulation of sediments and agro-chemicals in waterways.
