Red Soil: • Red soil develops reddish colour due to the diffusion of iron in crystalline and metamorphic rocks. • It looks yellow in a hydrated form. • It is highly porous and fertile when they are fine-grained and deep. • This soil is deficient in nitrogen, humus, phosphoric acid, magnesium, and lime but fairly rich in potash, with its pH ranging from neutral to acidic. • Cotton, wheat, rice, beans, millets, tobacco, oilseeds, potatoes, and fruits are some of the appropriate crops for red soils. • Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau. • They are also found in parts of Orissa, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats.
