SOIL

Black Soil is also known as 'Regur Soil' or 'Black Cotton Soil. Black Soil is found in Gujarat, Maharashtra, parts of Madhya Pradesh, South Uttar Pradesh, North-west Orissa and the western parts of Andhra Pradesh. The black soil consists of a large amount of clay. It also contains iron oxide, lime and magnesium carbonates in small amounts. It is also known as black cotton soil since it is suitable for growing cotton on account of its capacity to retain water.

In India, red soil develops on crystalline igneous rocks in areas experiencing low rainfall in the castern and southern parts of the Deccan plateau These soils are abundant along the eastern slopes of the Western Ghats, Odisha and Chhattisgarh and in the southern parts of the middle Ganga plain. The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks.

In the Eastern and Southern parts of the Deccan pla- teau, red soils have developed on crystalline, igne- ous rocks in areas of low rainfall. The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form.

Red soil is also known as the Omnibus group. It covers the largest area of Odisha. It is red because of Ferric oxide. It is found in the eastern and southern parts of the Deccan plateau, Orissa, Chhattisgarh and the middle Ganga plain. The main crops cultivated in red soil are wheat, cotton, pulses, tobacco, oilseeds, potato etc.

Cashew nuts thrive best in red laterite soil, which is formed through the weathering of laterite rocks. These soils are abundant in iron and aluminium and are typically characterized by a rusty-red hue as a result of their high iron oxide content. Red laterite soil is also commonly utilized for construction pur- poses. In Tamil Nadu, Andhra Pradesh, and Kerala, red laterite soils are particularly well-suited for tea plantations.

Lateritne soil, formed by leaching, is abundantly found in India's Eastern and Western coasts. This soil is found in regions having high temperatures and high rainfall

Most desert soils are called Aridisols (dry soil). These are porous sandy soils with low nitrogenous matter and humus. These are saline in nature too

Laterite is a deep red soil found in tropical regions and often formed on mafic igneous bedrock. The fertility of this soil is low. This soil is rich in iron oxide and aluminium oxide but lacks nitrogen, phosphoric acid, potash, lime and organic elements.
