Growing Millet in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Millet (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Millet's preferred 5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Millet's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Millet, which favours sandy. Mandera receives approximately 180 mm/year — well below Millet's minimum of 250 mm — so supplemental irrigation would be essential for this crop. Millet's full potential is about 700 kg/acre (~KES 40,600/acre at KES 58/kg), but at Mandera's 28/100 suitability a realistic target here is closer to 245 kg/acre (~KES 14,210/acre) unless the constraints above are addressed.
