Growing Bambara Nuts in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Possible but challenging — Nyamira is only marginally suited to Bambara Nuts. Nyamira's soil (pH 5.58, slightly acidic) gives Bambara Nuts a suitability score of 41/100. Match fertilizer to Nyamira's nitrogen and phosphorus levels for the best result.
Nyamira County is a challenging environment for Bambara Nuts (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 5–6.5 band Bambara Nuts prefers, so no lime is usually required. Nitrogen (0.84 g/kg), phosphorus (11.6 mg/kg) and potassium (148 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Nyamira is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Bambara Nuts is the #79 soil match of the 106 crops we assess for Nyamira County. Bambara Nuts's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Nyamira'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 Nyamira's soil: Sweet Potato, Soybeans, and Pineapple — each scores higher on the same soil.
