Engineer and COO of a digital platform for sustainable agricultural solutions Dhruv Sawhney has recommended a new organic microbial spray developed by the Indian Agricultural Research Institute (ICAR) in Delhi to Indian farmers to reduce air pollution from stubble burning. According to ICAR director Ashok Kumar Singh, the Pusa Decomposer has seven different forms of fungus that naturally exist in the soil. The microbial spray would quickly destroy the stubble that remained in the fields after paddy harvesting. After three weeks, the old stubble would be mixed into the soil and used as compost for the next planting season. New Delhi has India’s highest level of dangerous air pollution, with the worst year-round average for PM2.5 pollution of any capital city in the world. Over 4.2 million people die each year due to outdoor air pollution.
