Growing Millet in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a challenging environment for Millet (soil-match score 43/100) and will need significant amendment before planting. Local soils average pH 5.31 — moderately acidic and inside the 5–8 band Millet prefers, so no lime is usually required. Nitrogen (1.36 g/kg), phosphorus (12.5 mg/kg) and potassium (177 mg/kg) all meet Millet's requirements, so a maintenance fertilizer programme is enough. Millet prefers sandy soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. 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.
