Growing Rosemary in West Pokot
Soil suitability analysis based on West Pokot's nutrient profile
West Pokot County is well suited to Rosemary, scoring 76/100 on ShambaIQ's soil-match model. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 6–8 band Rosemary prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Rosemary's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Rosemary, which favours sandy loam. At current prices (about KES 150/kg) and a typical 2,500 kg/acre yield, a well-managed Rosemary crop here can gross roughly KES 375,000 per acre.
