Growing Sweet Potato in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is well suited to Sweet Potato, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 4.5–7 band Sweet Potato prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Sweet Potato's requirements, so a maintenance fertilizer programme is enough. Sweet Potato prefers sandy loam soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 18/kg) and a typical 5,000 kg/acre yield, a well-managed Sweet Potato crop here can gross roughly KES 90,000 per acre.
