Growing Macadamia in Kilifi
Soil suitability analysis based on Kilifi's nutrient profile
Generally not ideal — Kilifi is poorly suited to Macadamia. Kilifi's soil (pH 6.24, slightly acidic) gives Macadamia a suitability score of 2/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.
Kilifi County is a challenging environment for Macadamia (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.24 — 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 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Macadamia, which favours loam. At 150 m, the county sits below Macadamia's preferred altitude range (900–2100 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Macadamia is the #78 soil match of the 106 crops we assess for Kilifi County. Macadamia's full potential is about 1,800 kg/acre (~KES 198,000/acre at KES 110/kg), but at Kilifi's 2/100 suitability a realistic target here is closer to 45 kg/acre (~KES 4,950/acre) unless the constraints above are addressed.
Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.

Top dressing guide
Kilifi's nitrogen (0.8 g/kg) already meets Macadamia's 0.8 g/kg requirement, so this is a maintenance rate.
