Growing Macadamia in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Yes — Kisumu is well suited to Macadamia. Kisumu's soil (pH 5.54, slightly acidic) gives Macadamia a suitability score of 92/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

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. On ShambaIQ's soil-match model, Macadamia is the #2 soil match of the 106 crops we assess for Kisumu 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.
