Red Soil (Chuvanna Mannu)

Red soil is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forest, having thin organic and organic-mineral layers black brown leached layer resting on an illuvium red layer. Red soils are generally derived from crystalline rock. Red soils are an important resource.

• Red soils have greater potential for drainage than other soils and are porous, fine-grained and fertile.
• Red soils have a higher content of iron, aluminum, and lime and often have a high acidic condition.
• Red soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.
• The characteristics of red soil has a great impact on strength, imperviousness and anti pest control.
• Red soil is found suitable for concrete as an admixture of it which can be used in construction of buildings.
• Cotton, wheat, rice, beans, millets, tobacco, oilseeds, potatoes, and fruits are some of the appropriate crops for red soils.
• The red soils are mainly loamy
• The red soil is also rich in ferric oxides
• Red soil is apt for less water required plants
