Laterite Soils:
- These soils are formed due to the coming of wet and dry seasons alternately.
They are generally found in the areas of more than 200 cm rainfall. - More rainfall causes leaching away of laterite rocks because of which parts of
silica and lime go down and the compounds of iron and aluminum are left in the
form of soil. - These soils are found mainly on the Eastern and the Western Ghats, hilly areas of
Rajmahal, Kerala, Karnataka, and plateaus of Orissa, Chotanagpur and
Meghalaya. Their largest expansion is in Kerala. - These soils lack in lime, nitrogen, potash and humus. The paucity of lime makes
these soils acidic and so, they are suitable for tea plantation. - These are zonal soils
