Growing Foxtail Millet in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a challenging environment for Foxtail Millet (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Foxtail Millet's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Foxtail Millet's requirements, so a maintenance fertilizer programme is enough. Foxtail Millet prefers sandy loam soils, while Meru is largely clay loam, so drainage and organic-matter management matter more here. Foxtail Millet's full potential is about 700 kg/acre (~KES 35,000/acre at KES 50/kg), but at Meru's 42/100 suitability a realistic target here is closer to 368 kg/acre (~KES 18,400/acre) unless the constraints above are addressed.
