Where are fertile black soils found in Madhya Pradesh?

In Madhya Pradesh, fertile black soils—often referred to as regur or black cotton soils—are primarily found in the following regions:

• Malwa Plateau: This region, of volcanic origin, is a major area for these soils.123
• Narmada Valley: The fertile tracts along this river valley contain significant deposits of black soil.1
• Satpura Range: Parts of this mountain range are characterized by the presence of these soils.1
• Madhya Bharat Plateau: Black soils are also found in this northern region, alongside alluvial soils.4

These soils are derivatives of trap lava and are highly moisture-retentive, making them well-suited for agriculture, particularly for crops like cotton. While these areas contain fertile black soils, it is important to note that much of eastern Madhya Pradesh is instead covered by less-fertile red-to-yellow soils.21
