Growing Moringa in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Moringa. Wajir's soil (pH 8.4, alkaline) gives Moringa a suitability score of 16/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir County is a challenging environment for Moringa (soil-match score 16/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Moringa's preferred 6–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 mg/kg) all meet Moringa's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Moringa, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Moringa's minimum of 400 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Moringa is the #11 soil match of the 106 crops we assess for Wajir County. Moringa's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Wajir's 16/100 suitability a realistic target here is closer to 800 kg/acre (~KES 80,000/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.
