Growing Foxtail Millet in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Foxtail Millet can be grown in Samburu County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 8.28 the soil sits above Foxtail Millet's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.67 g/kg), phosphorus (42.1 mg/kg) and potassium (387 mg/kg) all meet Foxtail Millet's requirements, so a maintenance fertilizer programme is enough. 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 Samburu's 58/100 suitability a realistic target here is closer to 508 kg/acre (~KES 25,400/acre) unless the constraints above are addressed.
