(ii) Black Soils: The black soils vary in depth from a thin layer to a thick stratum. The typical soil derived from the Deccan trap is black cotton soil. It is common in Maharashtra, western parts of Madhya Pradesh, parts of Andhra Pradesh, parts of Gujarat, and some parts of Tamil Nadu. These soils may vary from clay to loam and are also called heavy soils. Many black soil areas have a high degree of fertility but some, especially in the uplands, are rather poor. These are suitable for the cultivation of rice and sugarcane. Drainage is poor in such soils.
