Geography GK • Pedology 17 min read Updated: July 21, 2026

🌱 Key Takeaways

8 Groups (ICAR): Classified into Alluvial, Black/Regur, Red/Yellow, Laterite, Arid/Desert, Forest/Mountain, Saline/Alkaline, and Peaty/Marshy groups.
Alluvial Giant: Covers 43-45% of India. Divided into young fertile floodplains (Khadar) and older kankar terraces (Bhangar).
Black Regur basalt: Clayey Deccan soils that crack when dry and swell when wet, mixing layers naturally via "self-ploughing".
Red soil ferric oxide: Crystalline granite origin. Red when dry due to ferric oxide coatings; yellow when hydrated.
Laterite leaching: High-rainfall tropical weathering washes out silica and lime, leaving behind iron-baked hard brick soils.
Arid Kankar layer: Desert soils with deep calcium carbonate deposits that block roots, irrigated by the Indira Gandhi Canal.
Saline Usar/Reh: Capillary salt crusts resulting from poor drainage and over-irrigation, reclaimed using gypsum.
Soil Health Crisis: Post-Green Revolution chemical imbalances, erosion of topsoil, and low Soil Organic Carbon (SOC).

The 5 Soil Architects: Weathering and Genesis

In earth sciences, pedology is the study of soils in their natural environment, detailing how parent rock minerals, atmospheric climate, topography slope drainage, biological humus, and geological time interact.

Parent Rock: Black soils inherit basaltic lava minerals; red soils emerge from crystalline granites.
Climate Weathering: High rainfall drives chemical leaching; dry heat increases evaporation and salt crusts.
Topography: Mountain slopes allow rapid run-off, leaving thin soils; plains accumulate deep river sediments.

For competitive exams like the UPSC Civil Services, state PSCs, and SSC CGL, understanding soil groups, chemical profiles, and agricultural distributions is essential. Let's study these systems.

Alluvial Soil: Fertile Indo-Gangetic Plains

Sourced from the Indus, Ganga, and Brahmaputra river networks, alluvial soils cover 43-45% of India:

Khadar: Light-colored, highly porous young flood silt deposited annually by monsoonal floods.
Bhangar: Older, darker clay-rich terraces containing hard calcium carbonate nodules (Kankar).
Mountain Foothills: Transition from pebble-rich dry Bhabar strips to swampy, jungle-rich Terai belts where streams re-emerge.

Black Soil (Regur): Tectonic Deccan Basalt

Covering 15-16.6% of India (Maharashtra, MP, Gujarat):

Basalt Origin: Weathered volcanic basaltic lava of the Deccan Traps.
Self-Ploughing: High clay content expands when wet, turning sticky. Dry weather shrinks the clay, opening deep cracks (10-15 cm wide) that naturally mix top and subsoil layers. Highly suited for cotton and soybean.

Red and Yellow Soil: Peninsular Crystalline Gneiss

Found across 18.5% of the peninsular block:

Ferric coating: Slow weathering of granite and gneiss crystal rocks. Ferric oxide coatings yield a rusty red color.
Hydration Yellow: When waterlogged in valley bottoms, red ferric oxide hydrates, turning yellow. Light and porous, ideal for millets (ragi) and groundnuts.

Laterite Soil: Leached Slopes and plantation

Covers 4.3% of the land (Western Ghats summits, Kerala, Assam hills):

Leaching: Monsoonal rain washes silica, potash, and lime down, leaving an acidic residue of iron and aluminum oxides.
Brick-hard: Soft and moldable when wet, but bakes into rock-hard building blocks (Latin *Later* = brick) when dry. Excels at supporting coffee (Chikmagalur) and cashews.

Arid, Mountain, Saline, and Peaty Soils

These soils represent specialized climatic and geographic developments:

Arid & Desert Soil (Thar): High salt accumulation and hard sub-surface calcium Kankar blocks. Revitalized by the Indira Gandhi Canal for wheat.
Forest & Mountain Soil: High organic humus conifer layers on mid-slopes, thin acidic soils on peaks, and fertile saffron silt in valleys.
Saline & Alkaline Soil (Usar/Reh/Kallar): High capillary salt crusts due to poor drainage and over-irrigation. Reclaimed using Gypsum (calcium sulphate).
Peaty & Marshy Soil (Kari): High organic black sponge (up to 50% humus) in Sundarbans and Kerala backwaters, hosting mangrove vegetation.

The Modern Crisis: Degradation and Reclamation

Modern intensive cultivation places stress on subcontinental soils:

Chemical Imbalance: Skewed N-P-K ratios due to urea over-fertilization, dropping soil organic carbon.
Erosion: Wind and runoff wash away millions of tons of topsoil annually.
Reclamation: Addressed via cover crop rotations, mulching with dry organic matter, and the government Soil Health Card Scheme.

Frequently Asked Questions

What is the difference between Khadar and Bhangar alluvial soils?

Khadar is the young, light-colored, highly fertile alluvial soil deposited annually by rivers in floodplains. Bhangar is the older, darker, more clayey alluvial soil found on elevated terraces above flood levels, containing calcium carbonate nodules (Kankar).

Why is black soil called 'self-ploughing'?

Black soil contains swelling clays. When dry, it shrinks and forms deep, wide cracks that allow organic debris to fall in. When wet, it swells and closes up, naturalizing and mixing the soil layers without manual turning.

How is laterite soil formed and what are its properties?

Laterite soil forms under high temperatures and heavy monsoon cycles through intense leaching. Soluble silica, lime, and potash are washed down, leaving behind iron and aluminum oxides. It is soft when wet and bakes rock-hard when dry.

What makes red soil red, and why does it sometimes appear yellow?

The reddish color comes from ferric oxide coatings on soil grains, weathered from granite. In low-lying, poorly drained valley areas, hydration transforms it into yellow-shaded hydrated iron oxide.

What is the Kankar layer in desert soil?

The Kankar layer is a hard sub-surface accumulation of calcium carbonate nodules. Found in arid soils, it blocks deep root penetration and limits water infiltration, requiring management for agriculture.

What is Usar or Reh soil, and how is it reclaimed?

Usar or Reh is saline/alkaline soil with a white salt crust formed by capillary action from over-irrigation. It is reclaimed by adding Gypsum (calcium sulphate) to displace sodium, flushing with water, and planting salt-tolerant crops.

What are the Bhabar and Terai zones?

Bhabar is a porous, pebble-strewn strip at the base of the Shivaliks where mountain streams sink underground. Terai is the marshy, jungle-rich zone just south of Bhabar where streams re-emerge, providing fertile soils for rice and sugarcane.

What are the primary chemical deficiencies in most Indian soils?

Due to intense cultivation and tropical climates, most Indian soils are deficient in Nitrogen, Phosphorus, and Organic Humus, though they are generally rich in Potash.

What are Laurasia and Gondwanaland?

When the supercontinent Pangea split during the Mesozoic era, it divided into two smaller supercontinents: Laurasia in the Northern Hemisphere (consisting of North America, Europe, and Asia) and Gondwanaland in the Southern Hemisphere (consisting of South America, Africa, India, Australia, and Antarctica).
