Growing Bambara Nuts in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

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. 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.
