Black soil is a type of residual soil.
These soils are locally known as the ‘Regur Soil’ or the ‘Black Cotton Soil’. Black cotton soil (regur soil) is highly argillaceous, i.e. clayey. It is deep and impermeable and thus has high water retention capacity.
Types of black soil:
- Shallow Black Soil: It exists in Satpura hills (Madhya Pradesh), Bhandara, Nagpur and Satara (Maharashtra), Bijapur and Gulbarga districts (Karnataka ). Crops like jowar, rice, wheat, gram and cotton grow in the soil.
- Medium Black Soil: It covers a larger area in Maharashtra, Gujarat, Madhya Pradesh, Tamil Nadu and Andhra Pradesh.
- Deep Black Soil: The soil is fertile and suitable for cotton, sugarcane, rice, citrus fruits, vegetables etc.
