Growing Napier Grass in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Kilifi County is a solid choice for Napier Grass, with a soil-match score of 67/100. 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 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/low/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Napier Grass, which favours loam. 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.
