How red soil developed but make its look red and yellow
Answers
it develops reddish due diffusion of iron in Crystalline and metamorphic rock and it looks yellow when it is in a hyadrated form
Red Soil and Yellow Soil
These distinct soils are named after their hues. Red soil gets its colour from the iron found in its composition in a crystallized form. The soil takes on a yellow colour when it is hydrated. These soils are generally found in the Western Ghats, Odisha and Chattisgarh.
The clay form of red soil is nutrient rich and viable for forestation. However coarse red or yellow soil has been completely leached of all its nutrients and is not fertile. Red soil actually has a very low level of humus and require fertilizers when used for farming.
Laterite Soil
Such soils are found in regions of high temperature and very high rainfall. The rains will wash all the nutrients from the soil, leaving it infertile. The leaching process will leave behind iron-rich soil, absent of silicon. The humus composition is also affected by bacteria and fungi that thrive in high temperatures.
Such soils are found in the hot and humid regions of Western Ghats, Eastern Ghats, Malwa Plateau, Tamil Nadu, Kerala etc. While these soils are not entirely suitable for agriculture they have other uses. they are used to make bricks which we use in constructions.
