Growing Macadamia in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is well suited to Macadamia, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Macadamia's requirements, so a maintenance fertilizer programme is enough. Macadamia prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 110/kg) and a typical 1,500 kg/acre yield, a well-managed Macadamia crop here can gross roughly KES 165,000 per acre.
