Major Soils of India
Major Soils of India
1. Clayey Soil (Chikni Mitti)
- Formed by very fine clay particles.
- Contains a large amount of nutrients.
- Retains water for a long time.
- Found mostly in plains and river valleys.
- Crops grown: Rice, wheat, pulses, fruits, and vegetables.
- Use: Suitable for crops that need more moisture, such as paddy.
2. Yellow Soil (Peeli Mitti)
- Yellow colour is due to the presence of iron and magnesium.
- Found in eastern parts of India.
- Has moderate fertility.
- Becomes red when iron content increases.
- Crops grown: Pulses, oilseeds, fruits.
- Use: Suitable for dry crops with proper manuring and irrigation.
3. Black Soil (Kaali Mitti)
- Also known as Regur Soil or Cotton Soil.
- Contains lime, iron, calcium, potassium, and magnesium.
- Nutrient composition:
- Nitrogen: 0.1–0.3%
- Phosphorus: 0.05–0.1%
- Potassium: 1–3%
- Calcium: 2–6%
- Magnesium: 1–3%
- Iron: 1–3%
- Retains moisture; cracks in summer help air circulation.
- Crops grown: Cotton, cereals, pulses, oilseeds, fruits, vegetables.
- Use: Ideal for cotton cultivation and dry farming areas.
4. Alluvial Soil (Jalod Mitti)
- Formed by deposition of rivers (Ganga, Brahmaputra, Indus).
- Very fertile and rich in organic matter.
- Nutrient composition:
- Nitrogen: 0.05–0.15%
- Phosphorus: 0.02–0.05%
- Potassium: 0.5–1.5%
- Calcium: 1–5%
- Magnesium: 0.5–2%
- Iron: 0.5–2%
- Found in northern plains and river valleys.
- Crops grown: Rice, wheat, sugarcane, pulses, fruits, vegetables.
- Use: Best soil for intensive agriculture; supports dense population.
5. Brown Soil (Bhuri Mitti)
- Has a brown colour due to organic matter and iron.
- Moderate fertility, needs fertilizers for better yield.
- Nutrient composition:
- Nitrogen: 0.01–0.05%
- Phosphorus: 0.02–0.05%
- Potassium: 0.5–1.5%
- Calcium: 1–3%
- Magnesium: 0.5–1.5%
- Iron: 0.5–1.5%
- Crops grown: Wheat, pulses, sugarcane, fruits, and vegetables.
- Use: Suitable for dryland farming and moderate rainfall regions.
6. Red Soil (Laal Mitti)
- Red colour due to iron oxide.
- Poor in nitrogen, phosphorus, and organic matter.
- Nutrient composition:
- Nitrogen: 0.05–0.1%
- Phosphorus: 0.02–0.05%
- Potassium: 0.5–1.5%
- Calcium: 1–3%
- Magnesium: 0.5–1.5%
- Iron: 1–2%
- Found in southern and eastern India.
- Crops grown: Millets, pulses, oilseeds, sugarcane, cotton, fruits, vegetables.
- Use: Needs manures and fertilizers for better productivity.
Summary of Uses
- Clayey Soil → For water-loving crops (rice).
- Yellow Soil → For pulses and oilseeds (needs manures).
- Black Soil → Best for cotton and dry crops.
- Alluvial Soil → Very fertile, supports all major crops.
- Brown Soil → For dryland crops like wheat and sugarcane.
- Red Soil → Needs fertilizers; grows pulses and millets.
