Black Soil in India and its importance

black soil

Black soil, also known as ‘Regur Soil’ or the ‘Black Cotton Soil’ is highly productive and fertile soil found in India.

Key features of Black Soil in India

1. Black soil covers most of the Deccan Plateau which includes parts of Maharashtra, Madhya Pradesh, Andra Pradesh, Gujarat, and some parts of Tamil Nadu.
2. These soils are generally clayey, deep, and impermeable (doesn’t allow water to pass through it).
3. The color of these soil ranges from deep black to grey.
4. They swell and become sticky when wet and shrink when dried.
5. This gives rise to wide cracks during the dry season and hence these soils are kind of ‘self ploughing’ soils.
6. Black soil displays the characteristics of slow ‘absorption’ and a slow ‘loss of moisture’ which helps in retaining moisture for a very long time and thus helps the crops, especially, the rain-fed ones, to sustain even during the dry season.
7. The black soils are rich in lime, iron, magnesia, and alumina. They also contain potash.
8. They lack in phosphorous, nitrogen, and organic matter.
