Growing Mango in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Mango. Wajir's soil (pH 8.4, alkaline) gives Mango a suitability score of 10/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
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. On ShambaIQ's soil-match model, Mango is the #16 soil match of the 106 crops we assess for Wajir County. Mango's full potential is about 8,000 kg/acre (~KES 80,000/acre at KES 10/kg), but at Wajir's 10/100 suitability a realistic target here is closer to 1,000 kg/acre (~KES 10,000/acre) unless the constraints above are addressed.
Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Wajir's nitrogen (0.52 g/kg) already meets Mango's 0.5 g/kg requirement, so this is a maintenance rate.
