Growing Bambara Nuts in Kericho

Soil suitability analysis based on Kericho's nutrient profile

Quick answer

Generally not ideal — Kericho is poorly suited to Bambara Nuts. Kericho's soil (pH 5.94, slightly acidic) gives Bambara Nuts a suitability score of 30/100. Match fertilizer to Kericho's nitrogen and phosphorus levels for the best result.

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. On ShambaIQ's soil-match model, Bambara Nuts is the #98 soil match of the 106 crops we assess for Kericho County. Bambara Nuts's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Kericho's 30/100 suitability a realistic target here is closer to 150 kg/acre (~KES 22,500/acre) unless the constraints above are addressed.

Better matched to Kericho's soil: Kale (Sukuma Wiki), Sweet Potato, and Wambugu Apples — each scores higher on the same soil.
