WAPCOS Survey on Farmers using Pusa Bio Decomposer
The auditors surveyed 79 farmers in 15 villages spread across four districts in Delhi. The key findings were:
Firstly, 90% of the farmers said that the stubble decomposed within 15-20 days, whereas it would previously take 40-50 days.
Secondly, after using Pusa-bio decomposer, the soil needs to be ploughed only once or twice, opposed to earlier 6-7 times.
Thirdly, the organic carbon content in the soil increased to 40 per cent as the stubble ended up becoming manure.
Fourthly, the soil-nitrogen levels increased by 24%, helpful bacteria content increased seven times and fungal content increased threefold.
