Major agricultural soil types in India
- Alluvial soils (43% area): Deposited by river systems across Indo-Gangetic and Brahmaputra plains; rich in potash, highly fertile, ideal for paddy, wheat, sugarcane, and pulses.
- Black soils / Regur soils (15% area): Formed from basaltic lava flows across Maharashtra, Gujarat, and MP; rich in montmorillonite clay with high water-retention, ideal for cotton, soybean, and groundnut.
- Red and yellow soils (18% area): Developed from crystalline igneous rocks in low rainfall zones of Tamil Nadu, Karnataka, and Odisha; rich in iron, responsive to irrigation and fertilizers for pulses and millets.
- Laterite soils: Formed under high temperatures and heavy tropical rainfall through intense leaching; acidic and low in nitrogen, suitable for cashew, tea, coffee, and rubber with soil conditioning.
- Arid and desert soils: Sandy, saline soils of western Rajasthan and Gujarat with low organic matter, productive under canal irrigation for bajra, guar, and mustard.
- Saline and alkaline soils: Characterized by high salt crusts in canal command areas, reclaimed with gypsum and drainage.
Soil testing and health management
Physical soil texture and chemical fertility vary widely even within a single village. Farmers should regularly test their field soil under the central Soil Health Card scheme to determine exact pH, electrical conductivity, organic carbon, and primary and micronutrient status.
Soil conservation practices
Implement conservation tillage, cover cropping, organic manuring, and balanced fertilization to protect topsoil from water and wind erosion while maintaining native microbial diversity.

Common questions
How many major soil groups are identified in India by ICAR?
ICAR classifies Indian soils into eight major groups: Alluvial, Black, Red and Yellow, Laterite, Arid, Saline/Alkaline, Peaty/Organic, and Forest soils.
Which soil covers the largest agricultural area in India?
Alluvial soil is the most widespread and fertile soil, covering over 40% of the total agricultural land area in the northern plains.
Why is black soil specifically called 'cotton soil'?
Black soil possesses high clay content and excellent moisture-holding capacity, creating ideal conditions for growing rainfed and irrigated cotton.
