Kilifi County is well suited to Sweet Corn, scoring 76/100 on ShambaIQ's soil-match model. Local soils average pH 6.24 — slightly acidic to near-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 0.8 g/kg, P 11 mg/kg, K 109 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. On ShambaIQ's soil-match model, Sweet Corn is the #42 soil match of the 106 crops we assess for Kilifi County.
