Growing Mango in Elgeyo Marakwet

Soil suitability analysis based on Elgeyo Marakwet's nutrient profile

Elgeyo Marakwet County is a challenging environment for Mango (soil-match score 38/100) and will need significant amendment before planting. Local soils average pH 6.27 — slightly acidic to near-neutral and inside the 5.5–8.5 band Mango prefers, so no lime is usually required. Nitrogen (1.39 g/kg), phosphorus (22.2 mg/kg) and potassium (213 mg/kg) all meet Mango's requirements, so a maintenance fertilizer programme is enough. Mango prefers sandy soils, while Elgeyo Marakwet is largely clay loam, so drainage and organic-matter management matter more here. At 1800 m, the county sits above Mango's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. Mango's full potential is about 8,000 kg/acre (~KES 80,000/acre at KES 10/kg), but at Elgeyo Marakwet's 38/100 suitability a realistic target here is closer to 3,800 kg/acre (~KES 38,000/acre) unless the constraints above are addressed.
