As part of the Khet Bachao Abhiyan, scientists from ICAR-Central Marine Fisheries Research Institute (CMFRI) engaged with over 200 farmers, emphasizing the importance of balanced fertilizer use and transitioning to natural farming methods. The initiative aimed to address concerns about soil degradation due to excessive chemical inputs.
The awareness program highlighted the adverse effects of indiscriminate fertilizer application on soil health, water resources, and aquatic ecosystems. Experts cautioned that the overreliance on chemical fertilizers was disrupting nutrient balance, leading to pollution, greenhouse gas emissions, and ecological harm.
Dr. K.S. Karthika, a senior scientist at CMFRI, pointed out that excessive fertilizer usage not only impacts soil quality but also harms aquatic ecosystems through nutrient runoff and environmental damage. The institute showcased various indigenous technologies to promote sustainable agriculture and establish a circular bioeconomy.
These innovations included seaweed-based bio-fertilizers, organic manure derived from fish waste known as ‘Fishliser,’ and solutions based on Black Soldier Fly (BSF) for recycling biological resources. Dr. Grinson George, the Director of CMFRI, emphasized that these technologies could enhance soil health and encourage environmentally friendly farming practices.
The program also introduced the use of BSF larvae as an alternative fish feed and a sustainable method for organic waste management. Farmers participating in the initiative received BSF fertilizers and larvae. CMFRI scientists have engaged with around 1,500 farmers across 12 districts in Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, and Gujarat in the last two months.
They have conducted awareness campaigns in approximately 30 farming villages in Kerala to educate locals on the importance of responsible fertilizer use in protecting soil and aquatic resources. This initiative aligns with the goal of reducing agricultural input costs, restoring soil fertility, and promoting climate-resilient farming practices.
