Growing Millet in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a challenging environment for Millet (soil-match score 39/100) and will need significant amendment before planting. Local soils average pH 5.38 — moderately acidic and inside the 5–8 band Millet prefers, so no lime is usually required. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Millet's requirements, so a maintenance fertilizer programme is enough. Millet prefers sandy soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 m, the county sits above Millet's preferred altitude ceiling of 1800 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 58/kg) and a typical 600 kg/acre yield, a well-managed Millet crop here can gross roughly KES 34,800 per acre.
