Growing Napier Grass in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Kisumu County is well suited to Napier Grass, scoring 79/100 on ShambaIQ's soil-match model. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5–8 band Napier Grass prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Napier Grass's requirements, so a maintenance fertilizer programme is enough. Napier Grass prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 5/kg) and a typical 15,000 kg/acre yield, a well-managed Napier Grass crop here can gross roughly KES 75,000 per acre.
