Organic fertiliser: A must for the next green revolution
Source: DTE Directions: This Article has been taken from Down to Earth. It highlights the potential of India to become an organic fertiliser hub. Make short notes on organic farming/natural farming. Context: With the right policy interventions, India can become the hub of organic fertiliser production What are organic fertilisers? Organic fertilisers are derived from animal products and plant residues containing sufficient Organic fertiliser can be categorised into two segments, according to government rules: Bio-fertilisers are composed of living microorganisms attached to solid or liquid carriers and are useful for cultivable land, as these microorganisms help in increasing the productivity of soil and/or crops. Organic manure refers to partially decomposed organic matter like digestate from a biogas plant, compost and vermicompost, which provides nutrients to the soil/crops and improves yield. The penetration of organic fertilisers is low: The proportion of organic fertilisers of the overall fertiliser consumption was only 0.34 per cent for 2019-20. With the promotion of biogas production, the government can reap the benefits of its bi-product — fertiliser. Potentials of organic fertilisers in India: Utilisation of Solid waste: India produces more than 150,000 tonnes of municipal solid waste (MSW), (According to the National Solid Waste Association of India and the Central Pollution Control Board. ) Considering collection efficiency of 80 per cent and the organic part of MSW to be 50 per cent, the total organic waste generated per day in India comes to around 65,000 tonnes per day. Even if half of this is diverted to the biogas industry, the government can leverage this by the reduction in import of fossils and fertilisers. Using Biogas/gobar gas plants effluents: these plants not only produce biogas but also organic fertilisers are known as digestate. Digestate can help realise the vision to have a second green revolution. Increase Soil fertility: Digestate can provide organic carbon to the continuously depleting soil, apart from its standard nutrition value. In India at present, bio-fertiliser production is just over 110,000 tonnes and 34 million tonnes of organic manure, composed of farmyard manure, city compost and vermicompost, among others. Why India needs to promote production of organic fertlisers? Popularity:The popularity of organic farming has grown in the domestic market in recent years. Market size: The market size for Indian organic packaged food is expected to grow at a rate of 17 per cent and cross Rs 871 million by 2021. Growing awareness: The significant rise of this sector is linked to growing awareness about the harmful effects of synthetic fertiliser on soil, rising health concerns, expanding urban population base and an increased consumer expenditure on food goods. SATAT Scheme: Bio-compressed natural gas (bio-CNG) and solid organic manure or digestate can be produced in large quantities under the SATAT programme, under which more than 5,000 projects have been started across the country by the industry. Since organic manure can be improved with the use of bio fertilisers to meet nutrient requirements, both biofertilizers and organic manure have the potential to eliminate the usage of synthetic fertilisers completely.
