Growing Rosemary in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Uasin Gishu County is well suited to Rosemary, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 6–8 band Rosemary prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Rosemary's requirements, so a maintenance fertilizer programme is enough. Rosemary prefers sandy loam soils, while Uasin Gishu is largely clay loam, so drainage and organic-matter management matter more here. 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.
