Growing Tea in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Trans Nzoia County is well suited to Tea, scoring 90/100 on ShambaIQ's soil-match model. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 4.5–6.5 band Tea prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 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.
