Growing Mango in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Mango can be grown in Murang'a County, but the soil scores 46/100 and needs targeted management to reach full potential. At an average pH of 5.03 the soil is moderately acidic, below Mango's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Mango's requirements, so a maintenance fertilizer programme is enough. Mango prefers sandy soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. At 1500 m, the county sits above Mango's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 10/kg) and a typical 2,800 kg/acre yield, a well-managed Mango crop here can gross roughly KES 28,000 per acre.
