Answer:
Soil, the biologically active, porous medium that has developed in the uppermost layer of Earth’s crust. Soil is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of injurious wastes, and as a participant in the cycling of carbon and other elements through the global ecosystem. It has evolved through weathering processes driven by biological, climatic, geologic, and topographic influences.
The various methods of soil conservation are as follows:
Contour ploughing: Ploughing along the contour lines can check the flow of water down the slopes. It is called contour ploughing. It can be practiced on the hills.
Terrace cultivation: Steps can be cut out on the slopes making terraces. It restricts soil erosion. It is practiced in western and central Himalayas.
Strip cropping: Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of wind. This method is called strip cropping.
Planting of shelter belts: Planting lines of trees to create shelter also checks the soil erosion. Rows of such trees are called Shelter Belts. These shelter belts have contributed significantly to the stabilization of sand dunes and in stabilizing the desert in western India.
