Soil fertility is under substantial pressure in southern Mali. Huge population growth and booming cotton and livestock production sectors are steadily exhausting agricultural land. To sustain and diversify their agro-pastoral activities, farmers do not have any other option than to produce organic fertilizer from crop residues and animal manure from their farms. How do they manage production, what technical knowledge do they use, what rationale, and what are the constraints on them and their objectives? A CIRAD team decided to investigate.
