More than two-thirds of the cultivated area in Tamil Nadu is covered by red soils. They are in-situ formations, produced from the rock below under the influence of climatic conditions. The rocks are acidic, consisting of mica or red granites. The soils are shallow and open in texture. They have a low exchange capacity and are deficient in organic matter and plant nutrients.
