Which major soil group of India is locally referred to as 'Regur Soil' and is famous for its high clay content and moisture-retention capability?

💡 Solution & Explanation

Black soil, widely known as Regur soil or black cotton soil, is derived from volcanic basaltic rocks and covers large parts of the Deccan plateau. Its high proportion of montmorillonite clay gives it a remarkable capacity to retain moisture and develop deep cracks during dry spells.
