Growing Cashew Nuts in Bungoma

Soil suitability analysis based on Bungoma's nutrient profile

Bungoma County is a challenging environment for Cashew Nuts (soil-match score 9/100) and will need significant amendment before planting. Local soils average pH 5.56 — slightly acidic to near-neutral and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. Nitrogen (1.12 g/kg), phosphorus (15.7 mg/kg) and potassium (161 mg/kg) all meet Cashew Nuts's requirements, so a maintenance fertilizer programme is enough. Cashew Nuts prefers sandy soils, while Bungoma is largely clay loam, so drainage and organic-matter management matter more here. At 1500 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 Bungoma County. Cashew Nuts's full potential is about 900 kg/acre (~KES 247,500/acre at KES 275/kg), but at Bungoma's 9/100 suitability a realistic target here is closer to 101 kg/acre (~KES 27,775/acre) unless the constraints above are addressed.

Better matched to Bungoma's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
