Growing Finger Millet in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Finger Millet (soil-match score 30/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Finger Millet's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/low/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Finger Millet, which favours sandy. At current prices (about KES 60/kg) and a typical 600 kg/acre yield, a well-managed Finger Millet crop here can gross roughly KES 36,000 per acre.
