ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Red soils are primarily found in regions with low to moderate rainfall, such as parts of Maharashtra, Tamil Nadu, Andhra Pradesh, and Karnataka. These areas tend to have a dry or semi-arid climate, which is conducive to the formation of red soils.

Statement 2 is correct: The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks.

Statement 3 is correct: Red soils are typically poor in phosphates and nitrogen, but they are rich in potash and potassium, which makes them less fertile for crops that require those nutrients unless supplemented with fertilizers.

Statement 4 is not correct: While red soils are found in some parts of Maharashtra they do not cover the whole state, especially in regions with moderate rainfall and in areas with a hot climate.
