Growing Celery in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Celery (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Celery's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Celery prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Celery's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Celery's full potential is about 12,000 kg/acre (~KES 840,000/acre at KES 70/kg), but at Wajir's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
