Quick answer: Indian Soil Types are classified into six major categories by the Indian Council of Agricultural Research (ICAR):
  • Alluvial Soil
  • Black Soil
  • Red and Yellow Soil
  • Laterite Soil
  • Arid (Desert) Soil
  • Forest and Mountain Soil
Each type differs in texture, fertility, mineral composition, water-holding capacity, and crop suitability.

  • Suitable for irrigation
Major Crops
  • Wheat
  • Rice
  • Sugarcane
  • Pulses
  • Maize
  • Jute

3 Red & Yellow Soil

Gets its colour from iron oxide content in the parent rock.

Distribution
  • Tamil Nadu
  • Karnataka
  • Andhra Pradesh
  • Odisha

4 Laterite Soil

Develops in regions with high rainfall and high temperature, through a leaching process.

Distribution
  • Kerala
  • Karnataka
  • Tamil Nadu

  • Maharashtra
  • Assam
Characteristics
  • Rich in iron and aluminium
  • Acidic in nature
  • Poor in nitrogen
  • Poor in humus

  • Coconut

5 Desert Soil

Found mainly in arid regions with very low rainfall.

Distribution
  • Rajasthan
  • Gujarat
  • Haryana
Characteristics
  • Sandy texture
  • High salt content
  • Low moisture
  • Low organic matter
Major Crops
  • Bajra
  • Barley
  • Mustard

6 Forest & Mountain Soil

Occurs in mountainous regions; texture and fertility vary with altitude.

Distribution
  • Jammu & Kashmir
  • Himachal Pradesh
  • Uttarakhand
  • Arunachal Pradesh
  • Sikkim
Characteristics
  • Rich in humus
  • Acidic nature
  • Suitable for plantations
Major Crops
  • Tea
  • Coffee

YOUR SCORE 0 / 14
Previous Year Topic
Q1

Which soil is best suited for cotton cultivation?

Black soil's high moisture-retaining, clayey texture makes it ideal for cotton.
Previous Year Topic
Q2

Black soil is also known by which name?

Black soil is popularly called Regur Soil, or Black Cotton Soil.
Previous Year Topic
Q3

Which soil type is richest in humus?

Forest and Mountain Soil generally contains the highest amount of organic matter and humus.
Previous Year Topic
Q4

Which soil develops mainly due to river deposition?

Alluvial soil forms through the deposition of sediments carried by rivers.
Previous Year Topic
Q5

Which soil dominates the Deccan Plateau?

Black soil, formed from basaltic lava, is the dominant soil type across the Deccan Plateau.
Previous Year Topic
Q6

Which soil type is most suitable for tea cultivation?

Laterite soil, found in high-rainfall regions like the Western Ghats, suits tea cultivation well.
Previous Year Topic
Q7

Which of these soils is acidic in nature?

Laterite soil is acidic in nature, along with Forest and Mountain soil.
Extra Practice
Q8

Which soil type covers the largest area in India?

Alluvial soil covers the largest share of India's land area, roughly 40%, concentrated in the Northern Plains.
Extra Practice
Q9

The Bangar and Khadar classification belongs to which soil?

Alluvial soil is divided into older alluvium (Bangar) and newer alluvium (Khadar).
Extra Practice
Q10

What gives red soil its characteristic colour?

Red soil gets its colour from iron oxide present in the parent rock.
Extra Practice
Q11

Which process leads to the formation of Laterite soil?

Laterite soil forms through intense leaching, where heavy rainfall washes away soluble nutrients, leaving iron and aluminium behind.
Extra Practice
Q12

Desert soil is typically deficient in which of these?

Desert soil has low moisture and low organic matter, but a relatively high salt content.
Extra Practice
Q13

Which soil is developed from basaltic lava rock?

Black soil forms from the weathering of basaltic lava rock, mainly across the Deccan Trap region.
Extra Practice
Q14

Which soil type varies in texture with altitude in mountainous regions?

Forest and Mountain soil texture and fertility change with elevation, from coarse upper slopes to finer valley soils.

✅ Preparation Tips

  • Learn soil distribution alongside a map
