Alluvial soils are the most extensive soil group in India, covering about 43% of the total land area.

Black soils, also known as regur soils, are predominantly found in the Deccan Plateau region of India, covering states like Maharashtra, Karnataka, Andhra Pradesh, and Telangana.

Red soils, also known as red sandy soils, are characterized by their reddish color and are commonly found in the peninsular region of India, including states like Tamil Nadu, Karnataka, and Andhra Pradesh.

Laterite soils are known for their high iron and aluminum content and are commonly found in the Malabar Coast of India, including states like Kerala and Karnataka.

Peaty soils are formed due to the accumulation of organic matter and are commonly found in the deltaic regions of India, including the Sundarbans in West Bengal and the Mahanadi Delta in Odisha.

Clayey soils are characterized by their high clay content and are commonly found in the floodplains of rivers, where fine particles are deposited during flooding.

Volcanic soils are known for their high fertility and are commonly found in the volcanic regions of India, including the Deccan Plateau and the North-Eastern states.

Sandy soils are characterized by their coarse texture and are commonly found in the desert regions of India, including the Thar Desert in Rajasthan and the Rann of Kutch in Gujarat.

Saline soils are known for their high salinity and are commonly found in the coastal regions of India, where seawater intrusion and evaporation can lead to the accumulation of salts in the soil.

Mountain soils are characterized by their low fertility and are commonly found in the mountainous regions of India, where steep slopes and high altitudes can limit soil development and plant growth.

Forest soils are known for their high organic matter content and are commonly found in the forest regions of India, where the decomposition of plant material contributes to the accumulation of organic matter in the soil.

Calcareous soils are characterized by their high calcium carbonate content and are commonly found in the arid and semi-arid regions of India, where low rainfall and high evaporation can lead to the accumulation of calcium carbonate in the soil.

Phosphate-rich soils are known for their high phosphate content and are commonly found in the sedimentary basins of India, where the weathering of phosphate-rich rocks can lead to the accumulation of phosphorus in the soil.

Potash-rich soils are characterized by their high potash content and are commonly found in the granitic regions of India, where the weathering of potash-rich minerals can lead to the accumulation of potassium in the soil.

Sulfur-rich soils are known for their high sulfur content and are commonly found in the volcanic regions of India, where the weathering of sulfur-rich volcanic rocks can lead to the accumulation of sulfur in the soil.
