Delhi govt to spray bio-decomposer in fields to prevent stubble burning:
Delhi Chief Minister Arvind Kejriwal has announced that the Delhi government will start spraying bio-decomposer solution prepared by Pusa Research Institute from October 11 to prevent stubble burning.
What’s the plan?
- Pusa Research Institute has developed capsules containing bio-decomposers.
- These capsules are mixed with a solution.
- When applied on fields, it dissolves the stem of stubble, converts it into compost, fertility of land increases and less fertiliser is used.
- Delhi government will provide the solution to farmers free of cost and spray it in farms.
- The solution will help in the disposal of stubble, without the involvement of stubble burning.
How were these bio-decomposers formed?
Pusa Decomposer is a mix of seven fungi that produce enzymes to digest cellulose, lignin and pectin in paddy straw.
- The fungi thrive at 30-32 degree Celsius, which is the temperature prevailing when paddy is harvested and wheat is sown.
The IARI has commercialised the technology. It has licensed six companies.
