PUSA Decomposers
Subject :Environment
Context: Decomposers to be used for stubble
Details:
- The decomposers are in the form of capsules made by extracting fungi strains that help the paddy straw to decompose at a much faster rate than usual.
- The fungi help to produce the essential enzymes for the degradation process.
Decomposer Mixture:
- It involves making a liquid formulation 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 litres of the liquid mixture with 4 capsules, jaggery, and chickpea flour. The mixture is sufficient to cover 1 hectare of land.
Time to Decompose:
- It takes around 20 days for the degradation process to be completed.
- Under usual circumstances, shredded and watered paddy straw, which is mixed with soil, takes at least 45 days to decompose.
- It does not give enough time for farmers to prepare fields for the wheat crop on time.
Benefits:
- The decomposer improves the fertility and productivity of the soil as the stubble works as manure and compost for the crops and lesser fertilizer consumption is required in the future.
- The soil loses its richness due to stubble burning and it also destroys the useful bacteria and fungi in the soil, apart from causing harm to the environment.
- It is an efficient and effective, 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.
