SOILS
Soil-types in India can be classified into three groups. The first group comprises of the alluvial, black and red soils, which are basically fertile and are arable and cultivatable.
The second group consists of the peaty and marshy, the saline and alkaline soils which are potentially arable.
The third group is the laterite and forest and hill soils, which are not at all suitable for cultivation.
The main alluvial area is found in the Indo-Gangetic plain and the Peninsular regions. The main crops are rice, sugarcane and wheat. Black soil is found in the northwestern regions and in the Deccan lava areas and Tamilnadu.
Black soil is especially suited for cotton. Red soil is particularly rich in potash and is found in northern and central India. The peaty and marshy soils are found in the Bengal deltas, Saline and alkaline soils in the semi-arid regions of Bihar, U.P, Gujarat, Punjab and Rajasthan. Desert soils are found in the minimum rain receiving areas of Gujarat, Punjab and Rajasthan. Laterite soil is common in the low hills of Andhra, Karnataka, Kerala, Madhya Pradesh, Odisha and Assam.
There are two crop seasons: Kharif, Rabi. The major Kharif crops are rice, jowar, maize, cotton, sugarcane, sesame and groundnut. The Rabi crops are wheat, jowar, barley, gram, rapeseed and mustard and the summer crops are rice, maize, groundnut and some cash crops.
