A solution to stubble burning: ICAR-PUSA Compost/ Decomposer Technology
Publish Date : 15-12-2020
Description : Stubble burning in the adjacent states of Punjab & Haryana has become one of the major contributory factors of the depleting air quality and increased pollution levels across some of the North Indian states including the landlocked national capital, especially in the months of September, October onwards every year. Stubble burning is a practice of burning the crop residue after harvesting summer paddy crop, followed by farmers in Punjab, Haryana and parts of Uttar Pradesh, mainly to get the land ready for the next crop, i.e, wheat. The narrow gap between the two crop seasons, non-availability of labor are important factors besides stubble burning being the cost most effective option. Research institutions like the Indian Agricultural Research Institute (IARI), under the ageis of ICAR, have been working on a cost effective yet simple solution for managing crop residues and help reduce air pollution. Years of research have resulted in this technology called ‘Pusa compost/ Decomposer’, a combination product of eight microbes, made available in ‘capsule form’ for decomposing the stubbles and help ready the land for the sowing of the next crop without the farmers burning the crop residue. According to the innovators of this technology, just ‘Four capsules’, which will cost a very minimal amount of money, can be used to make 25 liters of solution sufficient clearing stubbles on one hectare of land. The technology complements other available methods by hastening stubble decomposition.
