Show answer and solution
Answer: (D) Black soil
Black (regur) soil formed from Deccan basalt retains moisture and is rich in lime, iron, magnesium and alumina, making it ideal for cotton, hence the name black cotton soil. Red soil is poor in nitrogen, laterite is leached and acidic, and alluvial soils suit rice and wheat in the Indo-Gangetic plain.
