Growing Mango in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Nandi County is a challenging environment for Mango (soil-match score 30/100) and will need significant amendment before planting. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.5–8.5 band Mango prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Mango's requirements, so a maintenance fertilizer programme is enough. Mango prefers sandy soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. At 1900 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 Nandi's 30/100 suitability a realistic target here is closer to 3,000 kg/acre (~KES 30,000/acre) unless the constraints above are addressed.
