Soils
Alluvial Soils. Agriculturally the most important soils are the alluvial ones. It covers about 24% of the country’s total area.
Black Soils. Block soils cover an area of 5.18 sq. km; also called regur soil.
Red Soils. They comprise of red loams. Due to oxidation of ferro-magnesium these soils have developed in peninsular India.
Laterite Soil. These are formed under conditions of high rainfall and temperature with alternate wet and dry periods. Exfoliation is observed in laterite soil
Arid & Desert Soils. These soils, characterised by high salt and low humus content, are to be found in Rajasthan, Haryana, Punjab, Rann of Kutch and other rain-shadow regions.
Saline and Alkali Soils. These soils develop along arid region in small patches. Also called reh, kallar and usar, they are infertile but can be reclaimed by good drainage.

Water erosion. Water erosion may be caused by rivers or rain.
