Black soils are also known as the ‘Regur Soil’ or the ‘Black Cotton Soil’. It covers most of the Deccan Plateau which includes parts of Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh and some parts of Tamil Nadu.
The black soil is formed by the weathering of igneous rocks and cooling of lava after a volcanic eruption.
Characteristics of black soils are:
• The black soils are generally clayey, deep and impermeable.
• They swell and become sticky when wet and shrink when dried.
• The black soils are rich in lime, iron, magnesia and alumina.
• They also contain potash.
• The colour of the soil ranges from deep black to grey.
