Growing Bambara Nuts in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is well suited to Bambara Nuts, scoring 75/100 on ShambaIQ's soil-match model. At an average pH of 4.99 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 (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Bambara Nuts, which favours sandy. 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.
