Contour ploughing is the best method for conserving soil on hills because it reduces soil erosion and improves water distribution. Contour plowing is a farming technique that involves plowing or planting across a slope, following its elevation contour lines.
Contour ploughing can reduce soil erosion by up to 50%. It does this by creating a water break that slows down the flow of water down slopes, allowing more time for the water to settle into the soil.
