Soil is one of the three major natural resources, alongside air and water. It is one of the marvellous products of nature and without which there would be no life.
Indian soils are generally divided into four broad types. These soil types are: 1) alluvial soils; 2) regur soils; 3) red soils and 4) laterite soils. ALLUVIAL SOILS: This is the most important and widespread category.
Afforestation:
The best way to conserve soil is to increase area under forests.
(ii) Strip Cropping:
Crops may be cultivated in alternate strips, parallel to one another
(vi) Terracing and Contour Bunding:
Terracing and contour bunding across the hill slopes is a very effective and one of the oldest methods of soil conservation.
