Nyamira County is well suited to Macadamia, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Macadamia, which favours loam. On ShambaIQ's soil-match model, Macadamia is the #4 soil match of the 106 crops we assess for Nyamira County. At current prices (about KES 110/kg) and a typical 1,800 kg/acre yield, a well-managed Macadamia crop here can gross roughly KES 198,000 per acre.
