Which of the following soil types, covering a major part of the Deccan trap region, is ideal for the cultivation of cotton and is locally known as 'Regur'?

💡 Solution & Explanation

Black cotton soils, locally called regur, develop across the Deccan trap region from the weathering of basaltic lava rocks and exhibit exceptional moisture retention properties. Laterite soils form instead in regions experiencing high temperature and heavy rainfall with alternate wet and dry spells. These regur soils expand significantly when wet and contract with deep cracks during dry summer months.
