Composting is a microbiologically mediated process that enhances crop productivity and resilience by converting organic waste into a nutrient-rich soil amendment. This sustainable practice augments soil fertility, structure, and water-holding capacity, thereby fostering improved crop yields and quality. Composting also contributes to climate change mitigation through carbon sequestration, reduces waste disposal in landfills, and promotes soil biodiversity. Furthermore, it conserves water resources, minimizes soil pollution, and protects ecosystem services. As a viable strategy for sustainable agriculture, composting offers numerous environmental benefits, including improved soil health, enhanced ecosystem resilience, and reduced environmental degradation. By integrating composting into agricultural and land management practices, stakeholders can promote ecological sustainability, ensure long-term food security, and contribute to a healthier environment.
