Growing Bambara Nuts in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Nairobi County is a solid choice for Bambara Nuts, with a soil-match score of 64/100. At an average pH of 6.85 the soil sits above Bambara Nuts's preferred 5–6.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Nairobi 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.
