Contour ploughing is a way of controlling soil erosion. Contour ploughing is a farming technique where farmers plough along the curves of a slope, rather than up and down. By following the natural contours of the land, water is more easily absorbed into the soil, reducing runoff and erosion. The rows of crops act as a barrier to further slow down the water, making it easier for the water to penetrate the soil. This technique can be used in areas where there is sloping land, and it has been shown to reduce soil erosion and help retain water in the soil, which is beneficial for crop growth. Overall, contour ploughing is an effective and sustainable way to prevent soil erosion while still allowing farmers to grow crops.
