Delhi govt to spray bio-decomposer in fields to prevent stubble burning:


Context:

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.
