Context:
Researchers at the Central University of Rajasthan (CUoR) successfully cultivated wheat in Ajmer’s desert land using an innovative biotechnology method called ‘soilification’, demonstrating a breakthrough in combating desertification and enhancing arid agriculture.
About Soilification Technology:
- A biotechnological approach that transforms loose desert sand into soil-like medium suitable for farming.
- Mechanism:
- Polymers: Cross-link sand particles to create structured soil.
- Bioformulations: Boost microbial activity, improving nutrient cycling and soil health.
- Water Retention: Reduces irrigation needs by binding sand particles.
- Stress Resistance: Strengthens crops against heat and arid conditions.
- Crops Tested: Wheat, bajra, guar gum, and chickpea.
Key Features:
- Reduced irrigation cycles (3–4 vs 5–6 in conventional desert farming).
- High yield: Wheat seed-to-harvest ratio of 1:20, double that of untreated desert soil.
- Low-cost and eco-friendly, converting barren desert into cultivable land.
Significance:
- Desertification Control: Mitigates Thar desert expansion toward NCR.
- Water Security: Optimizes groundwater usage in arid regions.
- Food Security: Enables cultivation of staple crops in desert areas.
