Murang'a County is well suited to Macadamia, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 5.03 — moderately acidic and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Macadamia's requirements, so a maintenance fertilizer programme is enough. Macadamia prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Macadamia is the #2 soil match of the 106 crops we assess for Murang'a 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.
