Nandi County is well suited to Yams, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.5–6.5 band Yams prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Yams's requirements, so a maintenance fertilizer programme is enough. Yams prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Yams is the #48 soil match of the 106 crops we assess for Nandi County. At current prices (about KES 80/kg) and a typical 7,000 kg/acre yield, a well-managed Yams crop here can gross roughly KES 560,000 per acre.
