Question on: JSS2 Agricultural science - Soil Conservation Practices
How do the different soil erosion control methods contribute to preventing the loss of fertile topsoil and ensuring sustainable agriculture?
Various soil erosion control methods such as contour ploughing, terracing, cover crops, and conservation tillage are effective in preventing the loss of fertile topsoil and promoting sustainable agriculture. Contour ploughing and terracing help reduce water runoff and soil erosion on sloped lands by slowing down the flow of water and trapping sediment. Cover crops protect the soil surface from erosion, improve soil structure, and enhance water infiltration. Conservation tillage practices minimise soil disturbance, preserve soil structure, and reduce erosion by leaving crop residues on the soil surface.
