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. Napier Grass's full potential is about 30,000 kg/acre (~KES 150,000/acre at KES 5/kg), but at Kilifi's 67/100 suitability a realistic target here is closer to 25,125 kg/acre (~KES 125,625/acre) unless the constraints above are addressed.
