Growing Cashew Nuts in Narok

Soil suitability analysis based on Narok's nutrient profile

Narok County is a challenging environment for Cashew Nuts (soil-match score 8/100) and will need significant amendment before planting. Local soils average pH 6.13 — slightly acidic to near-neutral and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. Nitrogen (1.63 g/kg), phosphorus (25.7 mg/kg) and potassium (234 mg/kg) all meet Cashew Nuts's requirements, so a maintenance fertilizer programme is enough. Cashew Nuts prefers sandy soils, while Narok is largely clay loam, so drainage and organic-matter management matter more here. At 1700 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 Narok County. Cashew Nuts's full potential is about 900 kg/acre (~KES 247,500/acre at KES 275/kg), but at Narok'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 Narok's soil: Finger Millet, Groundnuts, and Soybeans — each scores higher on the same soil.
