Detailed explanation-1: -Terracing is the method of agriculture in a hillside area. It is constructed by the successive cutting piece of slope to increase the surface area for plantation. The terraces form a series of steps, each at a higher level than the previous. It prevents the soil erosion and runoff.
Detailed explanation-2: -Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing. This is the best method to reduce the soil erosion in the hilly areas.
Detailed explanation-3: -In terrace farming, a terrace is a piece of the sloped plane that is cut into a series of successively receding platforms, that resemble steps. This prevents rain from washing away soil, hence preventing soil erosion.
Detailed explanation-4: -Terracing helps retain soil cover and fertility since water flows do not wash off the topsoil and nutrients. So, what is terracing in soil conservation? The slope is no longer as steep as it initially was. Water runoffs are slower due to leveled areas.
