It is a vital chapter of Indian geography. Different questions from this chapter are often asked in various competitive exams like SSC, RAIL, State PSC, CDS, and UPSC. Here we provide a brief note on the different types of soil in India.


•  Soil can be defined as the mixture of organic matter or humus, minerals, gases, liquids, and microorganisms that together support life.

• Soil is also commonly referred to as the top layer of the earth’s crust which supports life.
• This top layer or the outermost layer of the earth that is composed of soil is called Pedosphere. The word  ‘pedon‘ is a Greek word that means “ground” or “earth.

• The Pedosphere interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere.

Soil has four major functions 

• It provides a medium for plant growth.
• As a means of water storage, supply, and purification
• As a modifier of Earth’s atmosphere
• As a habitat for organisms

Biotic and Abiotic Factors of Soil

•  Soil is an important factor in our ecosystem, and it contains both biotic and abiotic factors.

Biotic factors
• Biotic factors include living things like various organisms, insects, plants, and animals.

Abiotic factor
 • Abiotic factor includes non-living things like minerals, water, and air.

•  Silicate minerals are the most common minerals found in the earth’s crusts. The most abundant silicates are feldspars.

• Soil provides essential metals for plant growth like  Nitrogen, Potassium, and Phosphorus and less common minerals like  Calcium, Magnesium, and Sulfur.

Composition of Soil

• Soil is made up of five main components. It includes__

1.  Mineral matter is obtained by the disintegration and decomposition of rocks by pressure and temperature.

2.  Organic matter is obtained by the decay of plant residues, animal remains, and microbial tissues.

3. Water, obtained from the atmosphere and the reactions in soil (chemical, physical and microbial)

4. Air or gas, from the atmosphere, reactions of roots, microbes, and chemicals in the soil.

5. Organisms like insects, worms, and  Micro-organisms like Small microbes.

Classification of Soil

♦  In ancient times based on fertility soil was classified into two main groups, these include
• Urvara — Fertile soil
• Usara — Sterile (Infertile soil)

♦ Based on texture, soil can be classified into 4 groups
• Sandy
• Clayey
• Silty
• Loam

♦ On the basis of colour, soil can be divided into 3 categories
• Red
• Yellow
• Black

Types of soil as per Indian standard

• In the year 1953, The Indian Council of Agricultural Research (ICAR) set up an All India Soil Survey Committee. According to the survey report of the Committee ICAR has classified the Indian soils into Eight major groups on the basis of their nature, genesis, coloru, composition, and location.

◘  List of the 8 major soil groups notified by ICAR
• Alluvial soils
• Black soils
• Red soils
• Laterite soils
• Forest and Mountain soils
• Arid and Desert soils
• Saline and Alkaline soils
• Marshy and Peaty soils

Details About the Types of soil as per Indian standard

Alluvial Soil of India

♦ General Features

Alluvial or Alluviam soil is the most important and most widespread soil group in India.
• It supports uninterrupted crop growth.

• Distributed over an area of 15 lakh sq. Km.
• Area covered In terms of Percentage – 45.6%.

• Transported and deposited through rivers and streams
• Soils range in nature from sandy loam to clay.
• The sand content decreases from the west to the east.

• The colour of the alluvial soils varies from mild gray to ash gray.
• Shades depends on the depth of the deposition.
The Alluvial soils are yet Immature.

• Alluvial soil located near the foothills of Shiwalik known as – Bhabar
• The Alluvia soil is the most productive soil in India because it supports wide plant growth.

♦ Location

Northern plains (Mainly Indo-Gangetic Plain).
• Punjab in the west, West Bengal, and Assam.
• River valleys and deltas of the Mahanadi, Godavari, Krishna, and Cauvery.

♦ Composition

• Potash, Phosphoric Acid (Rich)
• Nitrogen (Poor)
• Iron Oxide and Lime vary within a wide range.

◘ Two Types of Alluvial soil

♦ Khadar
New alluvium
• Deposited by floods annually
• Formed by depositing fine silts.

♦ Bhangar
Represents a system of older alluvium,
• Deposited away from the floodplains.

**Both the Khadar and Bhangar soils incorporate calcareous concretions (Kankars).
**these soils are greater loamy and clayey within the lower and center Ganga undeniable and the Brahmaputra valley

♦ Note:-
• Alluvial Soil located in the coastal area known as – Coastal Alluvium
• And Alluvial Soil located in the delta region of various rivers known as – Deltic Alluvium

 ♦ Suitable Crops

• Rice, Wheat, Sugarcane, Maize, Pulses, Oilseeds, Fruits and Vegetables, and Leguminous Crops.

Black Soil of India

 ♦ General Features

• Known as ‘Regur Soil’ or ‘Black Cotton Soil.
Highly retentive of moisture.
• They swell and become sticky when wet and shrink when dried.

• During the dry season, these soils develop wide cracks.
• Also called self-plowed soil.

• Because of this individual gradual absorption and loss of moisture, the black soil keeps the moisture for a completely long term.

• Important for rain-fed crops, to sustain even during the dry season.
• The coloration of the soil levels from deep black to gray.
• Percentage of the Back soil in India is 18.5%. 

Area covered

• Covers most of the Deccan Plateau.
• Madhya Pradesh
• Andhra Pradesh
• Some parts of Tamil Nadu.
• Upper reaches of the Godavari and the Krishna


• Rich in – Lime, iron, magnesia, and alumina. potash
• Poor in – Phosphorous, nitrogen, and organic matter

 ♦ Suitable Crops

• Cotton, Tobacco, Castor, Wheat, Jowar, millet, Sunflower.

 Red and Yellow Soil of India

General Features

Develops on crystalline igneous rocks
Reddish colour due to a wide diffusion of iron oxide.

Looks yellow when it occurs in a hydrated form.
• Fine-grained red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are poor in fertility.

Area Covered

Laterite Soil in India

Common Features

• Derived from the Latin word ‘Later’ means brick.
• Indefinitely durable, develop in areas with high temperature and high rainfall.

• These are the result of intense leaching due to tropical rains.
With rain, lime and silica are leached away.
• Due to intensive leaching the laterite soils generally lack fertility.

• Widely used as bricks for building houses.
