Growing Finger Millet in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Finger Millet (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Finger Millet's preferred 5–7 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 Finger Millet's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Finger Millet, which favours sandy. Finger Millet's full potential is about 800 kg/acre (~KES 48,000/acre at KES 60/kg), but at Samburu's 41/100 suitability a realistic target here is closer to 410 kg/acre (~KES 24,600/acre) unless the constraints above are addressed.
