Growing Celery in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Celery (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 7.95 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 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Celery prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 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 Turkana's 2/100 suitability a realistic target here is closer to 300 kg/acre (~KES 21,000/acre) unless the constraints above are addressed.
