Descripción
Composting is a natural process that transforms organic waste—such as crop residues, manure, and kitchen scraps—into a nutrient-rich soil amendment. This catalogue presents composting as a foundational Climate-Smart Agriculture practice.The benefits are substantial. Compost improves soil health by up to thirty-one percent, increases water-holding capacity by thirty-five to fifty-seven percent, and can boost crop yields by up to forty percent. It also reduces the need for synthetic fertilizers, cutting costs and avoiding greenhouse gas emissions.The catalogue covers essential components, including carbon-nitrogen balance, moisture, aeration, and temperature. It details multiple methods: aerobic composting, vermicomposting using earthworms, pit composting, and Bokashi fermentation. A step-by-step methodology guides users from site selection to finished compost.Well-suited for smallholders with access to manure and crop residues, composting builds long-term soil fertility, enhances drought resilience, and turns farm waste into a valuable resource.
