Question

difference between red, black, alluvial, laterite soils

Answer 1

Chemically, red soil is siliceous and aluminous, with free quartz as sand, but is rich in potassium, ranging from sand to clay with the majority being loamy. The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous.

Alluvial soil is formed due to the deposition of alluvium from the river whereas laterite soilis formed due to leaching in wet and hot areas. ... * Alluvial soil isn,t acidic whereas laterite soil is acidic and coarse. *Alluvial soilis found in peninsular region whereas laterite soil is found in areas of western ghats.

Soil Colour: Reddish brown in colour due to the presence of iron oxide. Other characteristic features: With rain, lime and silica are leached away, and soils rich in iron oxide and aluminium compound are left behind(thus the reddish brown colour).
