India with a population of 1.20 billion out of which, 74%, i.e., 800 million, population derive sustenance from agriculture, with about 40 % population in India below poverty line with limited resources to provide input-urea, Di-ammonium phosphate and potash. Obviously for rural population, a bio-fertilizer based on farm yard manure, solid waste, and agricultural waste material available in plenty could be considered a potential resource for rural India. Today increasing cost of chemical fertilizers along with declining yield are responsible for decreased fertility with a degradation of soil. Bio-fertilizers a viable and safe resource for farmers provides a lot of scope for local employment through decentralized rural infrastructure, more skills and capacities to address technology and production capacities of soils. Bio-fertilizer renovation was started from July, 2009 by Discovery Park Project at Rajiv Gandhi Institute of Information Technology,a campus of Indian Institute of Information Technology, Allahabad. The four blocks- Bhader, Bhetua, Amethi and Sangrampur with total population of 1120691 for four blocks combined together, were selected for this work, 25 thousands families in each block in the district, use bio-fertilizers out of 63 thousand families of the entire blocks. The application of bio-fertilizer as Nadap, Vermi-compost and Horn compost significantly improve yield and economics of various agricultural crops. On an average, compost contains 0.5-1.2 percent N, 0.2-0.5 percent P₂O₅ and 0.5-0.8 percent K₂O. Based on this analysis an average dressing of 25 tons per hectare of compost supplies 112 kg of N, 56 kg of P₂O₅ and 112 kg of K₂O. These quantities are not fully available to the crops in the year of application. Nitrogen is very slow acting and less than 30 percent of it is generally available to the first crop. About 60 to 70 percent of the phosphate and about 75 percent of the potash become available to the immediate crop. However, organic manures combination with 50% recommended dose of NPK significantly increased crop yield.
