Contour farming is an agricultural practice that involves plowing and planting across the slope of the land, following its natural contours. This method helps to reduce soil erosion by creating natural barriers that slow down water runoff, allowing it to soak into the soil instead. It is particularly effective on hilly or sloped terrain. Farmers often use contour farming in combination with other techniques, such as crop rotation and cover crops, to enhance soil health and improve crop yields. By maintaining the land's natural shape, this practice promotes sustainable farming and helps protect the environment from degradation.
