This soil is black in colour and is also known as regur soil. Climatic conditions along with the parent rock material are the important factors for the formation of black soil. The soil is ideal for growing cotton and is also known as black cotton soil. This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows. The soil covers the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh and extends in the south-east direction along the Godavari and the Krishna valleys.The black soils are made up of extremely fine i.e. clayey material and well-known for their capacity to hold moisture. Black soil is nutrients rich and contains calcium carbonate, magnesium, potash and lime. The soil is sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.Black Soil is ideal for growing cotton:

The entire northern plains are made of alluvial soil. 1. The Alluvial Soil is deposited by 3 important Himalayan river systems – the Indus, the Ganga and the Brahmaputra. 2. It is also found in Rajasthan, Gujarat and eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers. 3. The alluvial soil consists of various proportions of sand, silt and clay. As we move inlands towards the river valleys, soil particles appear to be bigger in size whereas in the upper side of the river valley, the soils are coarse. 4. Based on age, Alluvial soils can be classified as: 5. Old Alluvial (Bangar): The Bangar soil has a higher concentration of kanker nodules than the Khadar.6. New Alluvial (Khadar): It has more fine particles and is more fertile than the Bangar. 7. Alluvial soils are very fertile. These soils contain an adequate proportion of potash, phosphoric acid and lime, which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops..New Alluvival soil is more fine than bangar :
