Contour ploughing, also known as contour farming or contour cultivation, refers to a farming practice where the ploughing, planting, and cultivating of crops are done along the natural contours or level curves of the land. This method of farming helps to prevent soil erosion by reducing water runoff and retaining moisture on the soil surface. Other synonyms for contour ploughing include slope farming, slope tillage, slope planting, and level tillage. The use of this farming technique is important in protecting soil quality, conserving water, and enhancing crop yields. It is a sustainable and eco-friendly way of farming that helps to preserve the natural landscape and reduce environmental degradation.
