Red soil and its uses

• Red soils, along with their minor groups, form the largest soil group of India.
• The texture of these soils can vary from sand to clay, the majority being loams.
• They are acidic mainly due to the nature of the parent rocks. The alkali content is fair.
• They are poor in lime, magnesia, phosphates, nitrogen and humus.
• They are fairly rich in potash and potassium.
• The red colour is due to the presence of iron oxide.
• The red soils are mostly loamy and hence cannot retain water like the black soils.
• With the proper use of fertilizers and irrigation techniques, the red soils give a good yield of cotton, wheat, rice, pulses, millets, tobacco, oilseeds, potatoes and fruits.
• These soils are spread on almost the whole of Tamil Nadu.
