Growing Bambara Nuts in Kericho

Soil suitability analysis based on Kericho's nutrient profile

Kericho County is a challenging environment for Bambara Nuts (soil-match score 30/100) and will need significant amendment before planting. Local soils average pH 5.94 — slightly acidic to near-neutral and inside the 5–6.5 band Bambara Nuts prefers, so no lime is usually required. Nitrogen (1.34 g/kg), phosphorus (23.7 mg/kg) and potassium (225 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Kericho is largely clay, so drainage and organic-matter management matter more here. At 2000 m, the county sits above Bambara Nuts's preferred altitude ceiling of 1600 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 150/kg) and a typical 300 kg/acre yield, a well-managed Bambara Nuts crop here can gross roughly KES 45,000 per acre.
