Which of the following is a way of controlling soil erosion
Answer Details
Contour ploughing is a way of controlling soil erosion.
Soil erosion is the process of the removal of topsoil by agents such as wind or water. When the topsoil is removed, it leads to the loss of important nutrients and organic matter that are necessary for plant growth. Soil erosion also leads to the degradation of the soil structure, making it difficult for plants to grow.
Contour ploughing involves ploughing furrows along the contours of a slope rather than up and down. This helps to slow down the runoff of water and reduce soil erosion. By ploughing along the contour, the furrows act as a barrier that traps water and allows it to soak into the soil. This helps to improve the water-holding capacity of the soil, which is essential for plant growth.
In summary, contour ploughing is an effective way of controlling soil erosion because it helps to slow down the runoff of water and reduce soil loss.
