Growing Sweet Orange in Bomet
Soil suitability analysis based on Bomet's nutrient profile
Bomet County is a solid choice for Sweet Orange, with a soil-match score of 73/100. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 6–7.5 band Sweet Orange prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Sweet Orange's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Sweet Orange, which favours loam. At current prices (about KES 50/kg) and a typical 12,000 kg/acre yield, a well-managed Sweet Orange crop here can gross roughly KES 600,000 per acre.
