Uasin Gishu County is well suited to Stevia, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 6–7.5 band Stevia prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Stevia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Stevia, which favours loam. On ShambaIQ's soil-match model, Stevia is the #53 soil match of the 106 crops we assess for Uasin Gishu County. At current prices (about KES 200/kg) and a typical 3,000 kg/acre yield, a well-managed Stevia crop here can gross roughly KES 600,000 per acre.
