Growing Macadamia in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Quick answer

Yes — Bomet is well suited to Macadamia. Bomet's soil (pH 6.02, slightly acidic) gives Macadamia a suitability score of 89/100. Match fertilizer to Bomet's nitrogen and phosphorus levels for the best result.

Bomet County is well suited to Macadamia, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Macadamia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Macadamia, which favours loam. On ShambaIQ's soil-match model, Macadamia is the #19 soil match of the 106 crops we assess for Bomet County. At current prices (about KES 110/kg) and a typical 1,800 kg/acre yield, a well-managed Macadamia crop here can gross roughly KES 198,000 per acre.
