Conventional Biogas plants: Farmer’s Mini-manure Factory

Department of Environmental Science, Manipur University, Imphal – 795003

Attaining self-reliance in food for the teeming billion-plus population in India could only be ensured by boosting agricultural production, and this would not be achievable without chemical fertilisers. The consumption of mineral fertiliser has always been ahead of production, leading to wide-scale scarcity and disparity in availability and use. Chemical fertilisers, besides shortages and high cost, when in prolonged usage, result in human hazards and pollution of the environment. There is a growing realisation that natural farming methods involving farm resource use in an ecologically sustainable manner may be the answer to the environmental and agricultural problems. Against this backdrop, the nation's present-day farming community is compelled to take a second look at the biogas plant as a source of organic manure while tapping its energy. Biogas spent slurry is an excellent organic manure with a rich nutrient content that can be judiciously administered with mineral fertilisers under a well-planned integrated nutrient management practice. Using biogas spent slurry is environmentally sustainable as the inputs used are renewable and locally available, improve sanitation and hygiene, generate clean gaseous fuel, and address the issues of fuelwood crises that plague the rural areas.
