\nThe statement that black soils are rich in phosphorus and organic matter is incorrect.
\n<\/section>\n
\nBlack soils (Regur) are derived from weathering of basaltic rocks (Deccan Traps) and are rich in minerals like iron, lime, calcium, potash, aluminium, and magnesium. They have a high clay content, which gives them excellent moisture retention capacity. They are generally fertile and suitable for crops like cotton, sugarcane, groundnut, tobacco, and millets. However, they are typically deficient in nitrogen, phosphorus, and organic matter (humus).
\n<\/section>\n
\nThe deficiency in phosphorus and organic matter means that these nutrients often need to be supplemented through fertilizers for optimal crop yield, especially for nutrient-demanding crops like sugarcane. Their characteristic black colour is attributed to the presence of titanium salts and iron oxides.
