Crop residue burning has become a major environmental and agricultural challenge in India, especially after the harvest of rice and wheat. To address this issue, the Indian Agricultural Research Institute (IARI), New Delhi, developed an innovative and eco-friendly technology known as Pusa Decomposer.
What is Pusa Decomposer?
Pusa Decomposer is a biological formulation containing a consortium of beneficial fungi. These microorganisms accelerate the natural breakdown of crop residues such as paddy straw and wheat stubble, converting them into organic matter within 20–25 days.
How Does It Work?
The fungi present in Pusa Decomposer decompose complex plant materials like cellulose and lignin. As a result, crop residues are transformed into nutrient-rich organic matter, improving soil structure, microbial activity, and nutrient availability.
Benefits for Farmers and the Environment
- Eliminates the need for burning crop residues
- Improves soil fertility and organic carbon content
- Reduces input costs by lowering fertilizer requirements
- Supports timely sowing of the next crop
- Environment-friendly and safe for soil health
Method of Application
The decomposer capsules are activated in water with natural nutrients and sprayed evenly over the field after harvest. Under proper moisture conditions, the crop residue decomposes completely within a few weeks.
Why Pusa Decomposer Matters
Pusa Decomposer is not just a residue management tool—it is a sustainable farming solution. By reducing air pollution and restoring soil health, it offers long-term benefits to farmers while protecting the environment.
Conclusion
Pusa Decomposer provides a practical, low-cost, and eco-friendly alternative to crop residue burning. Its adoption can play a crucial role in promoting sustainable agriculture and cleaner air across India.
