Growing Finger Millet in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Finger Millet. Wajir's soil (pH 8.4, alkaline) gives Finger Millet a suitability score of 13/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir County is a challenging environment for Finger Millet (soil-match score 13/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Finger Millet's preferred 5–7 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 Finger Millet's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Finger Millet, which favours sandy. Wajir receives approximately 200 mm/year — well below Finger Millet's minimum of 400 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Finger Millet is the #14 soil match of the 106 crops we assess for Wajir County. Finger Millet's full potential is about 800 kg/acre (~KES 48,000/acre at KES 60/kg), but at Wajir's 13/100 suitability a realistic target here is closer to 130 kg/acre (~KES 7,800/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.
