Kitui County is well suited to Sweet Corn, scoring 78/100 on ShambaIQ's soil-match model. At an average pH of 7.03 the soil sits above Sweet Corn's preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Sweet Corn, which favours loam. On ShambaIQ's soil-match model, Sweet Corn is the #33 soil match of the 106 crops we assess for Kitui County.
