Growing Sweet Corn in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is well suited to Sweet Corn, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 6.76 — neutral and inside the 5.8–7 band Sweet Corn prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Sweet Corn, which favours loam. At current prices (about KES 40/kg) and a typical 8,000 kg/acre yield, a well-managed Sweet Corn crop here can gross roughly KES 320,000 per acre.
