Growing Bambara Nuts in Meru

Soil suitability analysis based on Meru's nutrient profile

Bambara Nuts can be grown in Meru County, but the soil scores 51/100 and needs targeted management to reach full potential. At an average pH of 4.88 the soil is strongly acidic, below Bambara Nuts's preferred 5–6.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Meru 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.
