Growing Bambara Nuts in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is a challenging environment for Bambara Nuts (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5–6.5 band Bambara Nuts prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. At 2100 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 #93 soil match of the 106 crops we assess for Uasin Gishu County. Bambara Nuts's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Uasin Gishu's 41/100 suitability a realistic target here is closer to 205 kg/acre (~KES 30,750/acre) unless the constraints above are addressed.

Better matched to Uasin Gishu's soil: Beans, Snow Peas, and Napier Grass — each scores higher on the same soil.
