What is PUSA Decomposer??

  • In 2020, the union government was testing an innovative method, the PUSA Decomposer.
  • It was developed at the Indian Agricultural Research Institute, Pusa.
  • The PUSA Decomposer is a set of four tablets made by extracting fungi strains that help the paddy straw to decompose at a faster rate.
  • This gives the farmers the option to shred the straw, spray a solution containing the fungal strains, and mix it with the soil for decomposition.
  • The fungi help to produce the essential enzymes for the degradation process.
  • If methods such as this become successful, it will be a new revolution in farming.
  • This has the potential to both reduce air pollution and increase soil fertility.

Working of PUSA Developer:

  • The window of time required for the solution to work, which is currently the main concern of farmers, is around 20 to 25 days.
  • The farmers argue that the window of time is too long for them, as they ideally wait about a week or 10 days after harvesting the non-basmati variety of rice to sow the wheat crop.
  • The scientists from IARI have said that the farmers do not necessarily have to plant the next crop in a rush and that 20-25 days is enough waiting time.

Significance of PUSA Decomposer:

  • The Decomposer improves the fertility and productivity of the soil as the stubble works as manure and compost for the crops and lesser fertiliser consumption is required in the future.
  • It is an effective and efficient, cheaper, doable, and practical technique to stop stubble burning.
  • It is an eco-friendly and environmentally useful technology and will contribute to achieving Swachh Bharat Mission.
