A new Bio Decomposer technique

• Chief Minister Arvind Kejriwal has said that the bio-decomposer technique of converting stubble into manure has shown success.
• This claim was based on the initial results from a farm where the bio-decomposing solution, developed under the guidance of the PUSA Institute, was being tried out by the Delhi government.

• 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.

How these decomposers are used on fields?

• A liquid formulation is formed using decomposer capsules and fermenting it over 8-10 days and then spraying the mixture on fields with crop stubble to ensure speedy bio-decomposition of the stubble.
• The farmers can prepare 25 litre of liquid mixture with 4 capsules, jaggery and chickpea flour. The mixture is sufficient to cover 1 hectare of land.
• It takes around 20 days for the degradation process to be completed.

Benefits of PUSA decomposers:

• 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 efficient and effective, cheaper, doable and practical technique to stop stubble burning.
• It is an eco-friendly and environmentally useful technology.
