Growing Cashew Nuts in Nakuru

Soil suitability analysis based on Nakuru's nutrient profile

Nakuru County is a challenging environment for Cashew Nuts (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 mg/kg) all meet Cashew Nuts's requirements, so a maintenance fertilizer programme is enough. Cashew Nuts prefers sandy soils, while Nakuru is largely clay loam, so drainage and organic-matter management matter more here. At 1750 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.
