Online Published on 09 January, 2024. Abstract Vermicomposting, the process of using earthworms to convert biodegradable material into nutrient-rich vermicast, stands as a fundamental practice in sustainable agriculture. Rich in growth-promoting hormones, enzymes, and microorganisms, vermicast significantly boosts plant growth and enhances resistance to diseases. Given the staggering global annual production of organic waste, expected to increase from 1.3 billion to 2.2 billion tons by 2025, vermicomposting emerges as an eco-friendly and organic fertilizer production method. Earthworms, historically revered as “natural ploughmen” by Charles Darwin, contribute to soil health, influencing microbial communities and nutrient availability while mitigating the effects of heavy metals. The application of vermicompost results in higher crop yields and improved fruit quality, emphasizing the need for careful nutrient balance. Vermicomposting positively influences soil structure, reducing bulk density, enhancing water retention, and mitigating nitrate leaching, thereby promoting environmental sustainability. Its favourable impact on soil biology, including microbial biomass and enzyme activity, fosters a healthier soil ecosystem. In conclusion, vermicomposting presents a precise and effective solution for organic waste management, playing a pivotal role in the future of agriculture and contributing significantly to environmental conservation.
