Growing Grapes in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Kilifi County is a solid choice for Grapes, with a soil-match score of 74/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Grapes, which favours loam. At current prices (about KES 150/kg) and a typical 8,000 kg/acre yield, a well-managed Grapes crop here can gross roughly KES 1,200,000 per acre.
