Local soils average pH 5.33 — moderately acidic and inside the 5–6.5 band Bambara Nuts prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.1 mg/kg) and potassium (134 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Siaya is largely clay loam, so drainage and organic-matter management matter more here.
