Growing Foxtail Millet in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a solid choice for Foxtail Millet, with a soil-match score of 67/100. At an average pH of 7.83 the soil sits above Foxtail Millet's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.46 g/kg, P 37.4 mg/kg, K 395 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Foxtail Millet, which favours sandy loam. Foxtail Millet's full potential is about 700 kg/acre (~KES 35,000/acre at KES 50/kg), but at Isiolo's 67/100 suitability a realistic target here is closer to 586 kg/acre (~KES 29,300/acre) unless the constraints above are addressed.
