Black soil, also known as Regur soil, is a type of soil rich in minerals and organic matter, primarily found in regions like India. It is characterized by its dark color, which is due to the high content of humus and clay. This soil is particularly fertile and is ideal for growing crops such as cotton, sorghum, and soybeans. The formation of black soil is linked to volcanic activity, which contributes to its nutrient-rich composition. It has excellent moisture retention capabilities, making it suitable for dryland farming. Farmers often prefer black soil for its ability to support sustainable agriculture and high crop yields.
