West Pokot County is well suited to Onion, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 6–7 band Onion prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Onion's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Onion, which favours sandy loam. On ShambaIQ's soil-match model, Onion is the #41 soil match of the 106 crops we assess for West Pokot County. 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.
