We produce an activated organic fertilizer built on a simple principle — biochar from sugarcane bagasse, charged with high-nitrogen organic inputs, creates a soil amendment that holds nutrients for years rather than weeks. The formulation blends broiler chicken manure, abattoir waste, and rabbit urine into a single compound that we process, mill, and cure on-site at Busoke. Each ingredient serves a specific biochemical role, and the combination produces what we call a carbon battery — a porous carbon matrix that traps nitrogen, phosphorus, and potassium deep in the root zone where crops can access them season after season.
The science behind this is well established but rarely applied at farm scale in East Africa. Biochar’s lattice structure — created during pyrolysis of the sugarcane bagasse — provides millions of microscopic pores that absorb and hold nutrients that would otherwise leach away with the rains. When we saturate that structure with the nitrogen-rich blend of chicken manure and rabbit urine before it reaches the field, we are effectively pre-loading the soil with a slow-release fertility reserve. The result is permanent carbon sequestration — the biochar does not decompose — combined with superior nutrient retention that outlasts any synthetic alternative. Our milling and mixing infrastructure allows us to control particle size and nutrient ratios, and every batch is formulated for Central Uganda’s laterite soils.
