Growing Macadamia in Elgeyo Marakwet
Soil suitability analysis based on Elgeyo Marakwet's nutrient profile
Elgeyo Marakwet County is well suited to Macadamia, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 6.27 — slightly acidic to near-neutral and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. Nitrogen (1.39 g/kg), phosphorus (22.2 mg/kg) and potassium (213 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. 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.
