Growing Macadamia in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Macadamia, with a soil-match score of 65/100. Local soils average pH 4.99 — strongly acidic and inside the 4.5–6.5 band Macadamia prefers, so no lime is usually required. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Macadamia's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Macadamia, which favours loam. Macadamia's full potential is about 1,800 kg/acre (~KES 198,000/acre at KES 110/kg), but at Laikipia's 65/100 suitability a realistic target here is closer to 1,463 kg/acre (~KES 160,930/acre) unless the constraints above are addressed.
