Growing Tea in Uasin Gishu
Soil suitability analysis based on Uasin Gishu's nutrient profile
Uasin Gishu County is well suited to Tea, scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 6.39 the soil sits above Tea's preferred 4.5–6 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Tea's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Tea, which favours clay. At current prices (about KES 25/kg) and a typical 2,200 kg/acre yield, a well-managed Tea crop here can gross roughly KES 55,000 per acre.
