Iron oxides, which often appear as thin coatings on soil particles or as hydrous ferric oxide, are primarily responsible for the soil's red color.
The third-largest soil category in India is identified by red soils.
It appears yellow when hydrated. Red dirt is more common in regions with little rainfall.
From Tamil Nadu in the South to Bundelkhand in the north, and from Raj Mahal in the east to Kathiawad in the west, they are primarily found on the Peninsula.
In the red soil, crops including potatoes, wheat, cotton, and tobacco are grown.
