aluvial soil is very fertile
black soil has ability to retain water and become sticky when wet
laterite soil os formed by leaching process

1. Alluvial Soils
= Formation: They are mainly derived from the debris brought down from the Himalayas or the silt left out by the retreating sea.
- Thus they are azonal soils.
Areas: Alluvial soils are widespread in the northern plains and the river valleys.
-Through a narrow corridor in Rajasthan, they extend into the plains of Gujarat.
-In the Peninsular region, they are found in deltas of the east coast and in the river valleys.
Soil texture: The alluvial soils vary in nature from sandy loam to clay.
- These soils are more loamy and clayey in the lower and middle Ganga plain and the Brahmaputra valley.
-The sand content decreases from the west to east.
2. black soil
These soils are locally known as the ‘Regur Soil’ or the ‘Black Cotton Soil’.
-Internationally, these are known as ‘tropical chernozems’.
-These soils are famous for the cultivation of cotton.
Formation: These have mainly formed from the Deccan Trap rocks —> Zonal Soils
Areas: These are found in the Deccan trap region.
-Black soil covers most of the Deccan Plateau which includes parts of:Maharashtra,Madhya Pradesh,Gujarat,Andhra Pradesh and some parts ofTamil Nadu.
Soil Texture: Black cotton soil (regur soil) is highly argillaceous i.e. clayey.
- It is deep and impermeable and thus has high water retention capacity.
3. laterite soil
The word laterite has been derived from the Latin word ‘Later’ which means brick.
-These soils when wet are as soft as butter but become hard and cloddy on drying. Therefore, these are widely cut as bricks for use in house construction.
Formation: The lateritic soils are particularly found on high flat erosion surfaces in areas of high(>200cm) and seasonal rainfall.
-The alternating wet and dry seasons lead to the leaching away of the siliceous matter of the rocks leaving behind the compounds of iron and aluminium.
- These are zonal soils.
Areas: These soils have mainly developed in the higher areas of the Peninsular plateau.
-The laterite soils are commonly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and the hilly areas of Orissa and Assam.
