Kwale County is well suited to Grapes, scoring 80/100 on ShambaIQ's soil-match model. Local soils average pH 6.76 — 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 0.93 g/kg, P 9.8 mg/kg, K 131 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. On ShambaIQ's soil-match model, Grapes is the #34 soil match of the 106 crops we assess for Kwale County. 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.
