Growing Mango in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Mango (soil-match score 8/100) and will need significant amendment before planting. Local soils average pH 8.38 — alkaline and inside the 5.5–8.5 band Mango prefers, so no lime is usually required. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Mango's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Mango, which favours sandy. Mandera receives approximately 180 mm/year — well below Mango's minimum of 500 mm — so supplemental irrigation would be essential for this crop. Mango's full potential is about 8,000 kg/acre (~KES 80,000/acre at KES 10/kg), but at Mandera's 8/100 suitability a realistic target here is closer to 800 kg/acre (~KES 8,000/acre) unless the constraints above are addressed.
