In Order to control soil erosion and conserve the soil, the following conservation practices are applied.
1.Conservational till farming (or) no-till- farming : In tradition method, the land is ploughed and soil is broken up and leveled to make a planting surface. This disturbs the soil and makes it susceptible to erosion. How ever, no-till-farming causes minimum disturbance to the top soil. Here the tilling machines make slits in the unploughed soil and inject seeds, fertilizers and water in the slit. So the seed germinates and the crop grows.
2.Contour farming : It Involves planting crops in rows across the contour of gently sloped land. Each row acts as a small dam to hold soil and to slow water runoff.
3.Terracing: It involves conversion of steep slopes into a series of broad terraces, which run across the contour. This retains water for crops and reduces the soil erosion By controlling runoff.
4.Alley cropping (or) Agro forestry : It involves planting crops in strips or alleys between rows of trees of shrubs, that can provide fruits and fuel wood. Even when the crop is harvested, the soil will not be eroded because trees and shrubs still remains on the soil and hold the soil particles.
5.Wind breaks or shelter belts : The trees are planted in long rows along the boundary of cultivated lands, which block the wind and reduces the soil erosion. Wind breaks help in retaining soil moisture, supply of some wood for fuel and provide habitat for birds.
