Growing Cashew Nuts in West Pokot

Soil suitability analysis based on West Pokot's nutrient profile

West Pokot County is a challenging environment for Cashew Nuts (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Cashew Nuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Cashew Nuts, which favours sandy. At 1500 m, the county sits above Cashew Nuts's preferred altitude ceiling of 700 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 275/kg) and a typical 900 kg/acre yield, a well-managed Cashew Nuts crop here can gross roughly KES 247,500 per acre.
