Nandi County is a solid choice for Onion, with a soil-match score of 73/100. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 6–7 band Onion prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Onion's requirements, so a maintenance fertilizer programme is enough. Onion prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 70/kg) and a typical 6,000 kg/acre yield, a well-managed Onion crop here can gross roughly KES 420,000 per acre.
