1 Answer

Answer :

These soils are black in colour and are also known as regur soils. Since black soil is ideal for growing cotton, it is also known as black cotton soil. It is believed that climatic conditions along with the parent rock material are the important factors for the formation of black soil. The type of soil is typical of the Deccan Trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows. They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Chhattisgarh and extend in the South east direction along the Godavari and the Krishna Valleys.
