Growing Mango in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a challenging environment for Mango (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Mango's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Mango's requirements, so a maintenance fertilizer programme is enough. Mango prefers sandy soils, while Meru is largely clay loam, 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.
