Growing Mango in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Mango (soil-match score 10/100) and will need significant amendment before planting. Local soils average pH 8.4 — alkaline and inside the 5.5–8.5 band Mango prefers, so no lime is usually required. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 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. Wajir receives approximately 200 mm/year — well below Mango's minimum of 500 mm — so supplemental irrigation would be essential for this crop. 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.
