The plantation in a huge manner to prevent soil erosion is called Shelter Belts. Plantation of protective belts of trees around a farmland prevents the action of external agents such as running water and wind on soil. Shelterbelt trees help to reduce soil erosion by protecting against wind and the elements and reducing the impact that severe weather has on the soil by providing much needed shelter. Shelterbelts can also provide protection to the shoreline by protecting against the impact of salt carried by the wind.

Regur soils is best suited for cotton. It is other name for black soil. Because of their clayey nature, black soil is much required for growing cotton. Cotton cultivation requires high moisture retention. Black soils are very fine grained and dark, contain a high proportion of calcium and magnesium carbonates and highly argillaceous.

Black soil derived from volcanic rocks with humus is suitable for growing Cotton. Cotton cultivation requires high moisture retention. Black soils are very fine grained and dark, contain a high proportion of calcium and magnesium carbonates and highly argillaceous. It is most suitable for the growth of cotton.
