Correct Answer: D
Solution :[d] The Indian soils belong to different categories and hence, differ greatly in their physical properties, chemical composition and fertility level. These are largely old and mature soils and are deficient in nitrogen, mineral salts and organic matter. Black soils are highly impermeable and water retentive due to predominance of clay. The formation of laterite soil takes place in those regions which experience wet and dry weather in alternative manner between the tropics.
