The geomorphological and climatic variations in India have developed different types of soil forms.
In 1965 S. They are based on the study of the research of Ram Chaudhary (I.C.A.R.) Indian Council of Agriculture Research (Indian Council of Agricultural Research has considered the types of Indian soils.
1. Allevial Soil
The money deposited by water is called alveolar alluvial soil. It is the God of the widest area of โโIndia.The northern vast a plains (Ganga, Indus, Brahmaputra), coastal plains (deposition of ocean waves and deltaic plains) are included under the Indian alluvial soil. The alluvial plains formed by rivers are found in mountainous regions (mountainous areas of Shivalik), plains (Punjab, Haryana, Rajasthan, Uttar Pradesh, Bihar, West Bengal) and deltaic part of peninsular India.
2. Red Soil
Geographically, it isthe second largest soil of India and the most extensive soil of peninsular India. (18.6% of the total geographical area) This soil has a predominance of iron element because due to leaching and transfer of soluble elements, the residual iron element reacts with oxygen to form iron oxide (ferric oxide), which gives the soil red color.
3. Black Soil
It is also called cotton soil and regur soil. This soil has developed as an endemic soil in the region of the Lava-Deccan Trap. Areas of this soil, most of Gujarat, Maharashtra, Karnataka and western Andhra Pradesh It is considered to be the third largest soil in India (second in peninsular India).It is 15.02% of the total geographical area of India. This soil is also called "Self Plowing Soil". The production of cotton, sugarcane, citrus crops is suin this soil.
4. Laterite Soil
Horizontal transfer of soluble elements due to high rainfall or sufficient rainfall and as a result of leaching into the lower layers of the soil, insoluble elements such as iron and aluminum are left here. This soil is found in the low areas of India. * Parallel to oceanic alluvial soil on Kerala/Malabar coast *Odisha and Andhra coast *Barind of West Bengal *Chhota Nagpur's Pat region, some on the Shillong plateau, some Assam region Laterite soils in the upper parts are acidic as compared to the lower parts. It is 3.7% of the total geographical area of โโIndia.
6. Arid and desert soils
As a result of geological movement in the long run, due to the uplift in this area, due to the transfer of surface water streams and ground water.
7. Saline and Alkaline Soils:
When the pH value of the soil is more than 7.2 then this soil is included in this category. When the soil is saline or alkaline, efforts are made to control it with artificial fertilize
