Explanation

Black soil (Regur) is formed from the weathering of volcanic rocks, particularly basalt from ancient lava flows. This soil is rich in iron, aluminum, and magnesium, giving it characteristic dark color and high fertility for cotton. The Deccan Plateau's extensive black soil regions originated from volcanic activity millions of years ago.
