How Bio-Decomposer Spray will Counter the Stubble Burning in Delhi?
Delhi Chief Minister Arvind Kejriwal announced on October 6, 2020 that the Delhi Government will be doing the Bio-Decomposer spraying from October 11, 2020 in order to counter the stubble burning issue. Bio-Decomposer spraying have been prepared by the scientists at the Indian Agricultural Research Institute, PUSA. It is a low-cost and an effective way to deal with the stubble burning issue.
What is the issue?
The stubble burning from neighbouring states including Uttar Pradesh, Haryana, Punjab contribute to 44% of Delhi Pollution. The farmers choose to burn the crop residue as they get very short time to prepare their field to sow the next winter crop known as Rabi crop after harvesting the monsoon crops known as kharif crops. Thereafter the retreating monsoon carries the smoke from the states of Punjab and Haryana to Delhi which gets stuck in the region. Thus, the winds deposit the smoke in Delhi leading to the problem of smog during winter.
How Bio-Decomposer Spraying will help?
A bio-decomposer capsule have been discovered by the scientists. These capsules will be sprayed on crop residue which will turn the residue into manure. The process increases the soil fertility and reduces the use of fertilizers. Delhi government have estimated that around Rs 20 lakhs will be required to manage 700 hectares of stubble using this method. The estimate is inclusive of cost of preparation, transportation and spraying.
The National Centre of Organic Farming also developed the waste decomposers earlier. The waste decomposers are used for quick composting of organic waste. It consists of micro organisms that are extracted from cow dung. The waste decomposers were also validated by the Indian Council of Agricultural Research (ICMR). As per the study, 30 grams of waste decomposer can decompose 1000 metric tonnes of waste within 30 days. Further, the decomposer is cost effective. 30 grams of it costs just Rs 20.
