This leaflet explains how farmers in northwest Vietnam process coffee husks into organic fertilizer. It details the benefits—improved soil health, reduced environmental pollution, lower fertilizer costs, and support for sustainable farming—and provides step-by-step guidance on composting. The method involves mixing coffee husks with manure, lime, phosphate, urea, and a microbial solution, ensuring proper moisture, and covering the pile to retain nutrients. It was published in June 2025 by NOMAFSI with ALiSEA support, based on a successful farmer experience.
