Kitui County is well suited to Groundnuts, scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 7.03 the soil sits above Groundnuts's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.74 g/kg), phosphorus (30.5 mg/kg) and potassium (339 mg/kg) all meet Groundnuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Groundnuts, which favours sandy. On ShambaIQ's soil-match model, Groundnuts is the #36 soil match of the 106 crops we assess for Kitui County. At current prices (about KES 90/kg) and a typical 500 kg/acre yield, a well-managed Groundnuts crop here can gross roughly KES 45,000 per acre.
