Nyandarua County is well suited to Tea, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 5.38 — moderately acidic and inside the 4.5–6 band Tea prefers, so no lime is usually required. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Tea's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay soils suit Tea, which favours clay. On ShambaIQ's soil-match model, Tea is the single best-matched crop of the 106 we assess for Nyandarua County. 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.
