Growing Foxtail Millet in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Foxtail Millet (soil-match score 25/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Foxtail Millet's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 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. Wajir receives approximately 200 mm/year — well below Foxtail Millet's minimum of 300 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Foxtail Millet is the #7 soil match of the 106 crops we assess for Wajir County. Foxtail Millet's full potential is about 700 kg/acre (~KES 35,000/acre at KES 50/kg), but at Wajir's 25/100 suitability a realistic target here is closer to 219 kg/acre (~KES 10,950/acre) unless the constraints above are addressed.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
