Alluvial soil [43%]
Red soil [18.5%]
Black / regur soil [15%]
Arid / desert soil
Laterite soil
Peaty Soil
Forest soil
mountain soil

Alluvial soil:

Mostly available soil in India (about 43%) which covers an area of 143 sq.km.Widespread in northern plains and river valleys.In peninsular-India, they are mostly found in deltas and estuaries. New alluvium is termed as Khadarand old alluvium is termed as Bhangar.

Colour: Light Grey to Ash Grey.

Texture: Sandy to silty loam or clay.

Red soil:

Seen mainly in low rainfall area. Also known as Omnibus group..

Colour: Red because of Ferric oxide. The lower layer is reddish yellow or yellow.

Texture:Sandy to clay and loamy.

Black soil / regur soil:

Regur means cotton – best soil for cotton cultivation. Most of the Deccan is occupied by Black soil.It is Mature soil.It has High water retaining capacity.Soils are Swells and will become sticky when wet and shrink when dried. Self-ploughing is a characteristic of the black soil as it develops wide cracks when dried.

Colour: Deep black to light black.

Laterite soil:

Name from Latin word ‘Later’ which means Brick.It becomes so soft when wet and so hard when dried. In the areas of high temperature and high rainfall.

Colour: Red colour due to iron oxide.

Desert / arid soil:

Seen under Arid and Semi-Arid conditions.

Colour:Red to Brown.

Texture:Sandy

Peaty / marshy soil:

Areas of heavy rainfall and high humidity.Growth of vegetation is very less.A large quantity of dead organic matter/humus which makes the soil alkaline

Forest soil:

Regions of high rainfall. Humus content is less and thus the soil is acidic.

Mountain soil:

In the mountain regions of the country. Immature soil with low humus and acidic.

Red	Eastern and southern part of the deccan plateau, Orissa, Chattisgarh and southern parts of the middle Ganga plain.	Iron and Potash	Nitrogen, Phosphorous and humus.	Wheat, rice, cotton, sugarcane and pulses
Laterite	Karnataka, Kerala, Tamilnadu, Madhya Pradesh, Assam and Orissa hills.	Western Rajastan, north Gujarat and southern Punjab	Organic matter, Nitrogen, Phosphate and Calcium	Cashewnuts, tea, coffee, rubber
Arid and Desert	Western Rajastan, north Gujarat and southern Punjab	Soluble salts, phosphate	Humus, Nitrogen	Only drought resistant and salt tolerant crops such as barley, rape, cotton, millets maize and pulses
Saline and Alkaline	Western Gujarat, deltas of eastern coast, Sunderban areas of West Bengal, Punjab and Haryana	Sodium, Potassium, Magnesium	Nitrogen and Calcium	Unfit for agriculture
