Growing Potato in West Pokot

Soil suitability analysis based on West Pokot's nutrient profile

Quick answer

Yes — West Pokot is well suited to Potato. West Pokot's soil (pH 6.04, slightly acidic) gives Potato a suitability score of 90/100. Match fertilizer to West Pokot's nitrogen and phosphorus levels for the best result.

West Pokot County is well suited to Potato, scoring 90/100 on ShambaIQ's soil-match model. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Potato's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Potato, which favours sandy loam. On ShambaIQ's soil-match model, Potato is the #28 soil match of the 106 crops we assess for West Pokot County. At current prices (about KES 38/kg) and a typical 8,000 kg/acre yield, a well-managed Potato crop here can gross roughly KES 304,000 per acre.
