Growing Moringa in Wajir

Soil suitability analysis based on Wajir's nutrient profile

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. 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.
