Growing Cashew Nuts in Nakuru

Soil suitability analysis based on Nakuru's nutrient profile

Quick answer

Generally not ideal — Nakuru is poorly suited to Cashew Nuts. Nakuru's soil (pH 6.28, slightly acidic) gives Cashew Nuts a suitability score of 8/100. Match fertilizer to Nakuru's nitrogen and phosphorus levels for the best result.

Nakuru County is a challenging environment for Cashew Nuts (soil-match score 8/100) 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 500 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Cashew Nuts is the #105 soil match of the 106 crops we assess for Nakuru County. Cashew Nuts's full potential is about 900 kg/acre (~KES 247,500/acre at KES 275/kg), but at Nakuru's 8/100 suitability a realistic target here is closer to 90 kg/acre (~KES 24,750/acre) unless the constraints above are addressed.

Better matched to Nakuru's soil: Carrot, Dolichos, and Garden Peas — each scores higher on the same soil.
