Growing Finger Millet in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Kitui County is well suited to Finger Millet, scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 7.03 the soil sits above Finger Millet'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 Finger Millet's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Finger Millet, which favours sandy. At current prices (about KES 60/kg) and a typical 800 kg/acre yield, a well-managed Finger Millet crop here can gross roughly KES 48,000 per acre.
