Explanation

Laterite is soil and rock type rich in iron and aluminium but poor in nitrogen, potash, potassium, lime and organic matter and is commonly considered to have formed in hot and wet tropical areas.

Nearly all laterites are of rusty-red colouration, because of high iron oxide content.
They develop by intensive and prolonged weathering of the underlying parent rock.
Tropical weathering (alteration) is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils.
The majority of the land area containing laterites is between the tropics of Cancer and Capricorn.
Laterite soil commonly found in areas of high altitude and heavy rainfall in Karnataka, TN, MP, Bihar, Orissa, Assam, and Meghalaya.
Plants like Cashew grow well along with Tapioca in this type of soil.
