Soil Health Management: 10 Practical Ways to Improve Soil Fertility Naturally in India

Key Exam Takeaways:

• 1. Green Manuring: Sow Dhaincha or Sunnhemp with pre-monsoon showers and incorporate into soil at 45-50 days before flowering.
• 2. In-Situ Crop Residue Management: Use Happy Seeders or waste decomposer sprays (Pusa Decomposer) rather than burning straw.
• 3. Dual Biofertilizer Inoculation: Apply Rhizobium/Azotobacter for nitrogen fixation and Phosphate Solubilizing Bacteria (PSB) to mobilize fixed phosphorus.
• 4. Vermicomposting: Apply 2 to 3 tonnes of Eisenia fetida vermicompost enriched with Trichoderma per acre.
• 5. Biochar Application: Pyrolyzed agricultural biomass retains water and nutrients permanently in degraded root zones.
• 6. Crop Rotation with Legumes: Never plant cereal after cereal; alternate with deep-rooted pulses to break pest cycles.
• 7. Organic Mulching: Maintain 3-4 inch straw cover to lower soil temperatures and stimulate earthworm tunneling.
• 8. Balanced Liming & Gypsum: Apply agricultural lime on acid soils (pH < 5.5) and Gypsum on sodic soils (ESP > 15%).
• 9. Periodic Soil Health Card Testing: Test soil every 2 years across 12 parameters to adjust fertilizer inputs precisely.
• 10. Controlled Minimal Tillage: Avoid excessive rotavator pulverization to preserve natural mycorrhizal fungal networks.
