Growing Napier Grass in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is well suited to Napier Grass, scoring 91/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5–8 band Napier Grass prefers, so no lime is usually required. The main gap is potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/low/medium demand — so the fertilizer plan below prioritises closing that deficit. Napier Grass prefers loam soils, while Mombasa is largely sandy, 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.
