Consider the following statements: 1. These soils are rich in bauxite or ferric oxides. 2. They are very poor in lime, magnesia, potash and nitrogen. 3. They are well developed in south Maharashtra, parts of Karnataka etc. and are widely scattered in other regions. 4. They are formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods. Above given statements are about which soil type in India?

The correct answer is Lateritic Soil.
Key Points
- Laterite – Lateritic Soils
- Laterite soils are mostly the end products of weathering.
- They are formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods.
- Heavy rainfall promotes leaching (nutrients gets washed away by water) of soil whereby lime and silica are leached away and a soil rich in oxides of iron and aluminum compounds is left behind.
- ‘Laterite’ means brick in Latin.
- They harden greatly on losing moisture.
- Laterite soils are red in colour due to little clay and more gravel of red sand-stones.
- Laterite soils are rich in bauxite or ferric oxides.
- They are very poor in lime, magnesia, potash, and nitrogen.
- Laterite soils cover an area of 2.48 lakh sq km.
- A continuous stretch of laterite soil is found on the summits of Western Ghats at 1000 to 1500 m above mean sea level, Eastern Ghats, the Rajmahal Hills, Vindhyan, Satpuras, and Malwa Plateau.
- They also occur at lower levels and in valleys in several other parts of the country.
- They are well developed in south Maharashtra, parts of Karnataka, etc. and are widely scattered in other regions.
- When manured and irrigated, some laterites are suitable for growing plantation crops like tea, coffee, rubber, cinchona, coconut, arecanut, etc.
