Healing Soils in India: For Better Crop Health and Human Nutrition’ Report
Healing Soils in India: For Better Crop Health and Human Nutrition’ Report It has been released by Indian Council for Research on International Economic Relations (ICRIER). Soil Erosion Soil Erosion refers to the loosening, detachment, transport, and deposition of topsoil particles from land surfaces by physical agents, primarily water and wind. In its natural form, also called geological erosion, soil removal occurs slowly and uniformly over long periods. Accelerated soil erosion, also known as man induced erosion, results from human altered land use patterns and removes soil at rates ten to several thousand times faster than natural soil formation. According to L.D. Meyer and W.H. Wischmeier soil particle detachability is the critical stage in erosion, controlled by grain size, cohesion, and flow velocity. Particles larger than 0.2 mm require higher water velocity for detachment. When erosion exceeds soil regeneration capac...
