Growing Celery in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Quick answer

Generally not ideal — Wajir is poorly suited to Celery. Wajir's soil (pH 8.4, alkaline) gives Celery a suitability score of 0/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.

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. On ShambaIQ's soil-match model, Celery is the #106 soil match of the 106 crops we assess for Wajir County. 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.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Bags per acre in Wajir
0.750.5

Wajir's nitrogen (0.52 g/kg) is 43% of the 1.2 g/kg Celery needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
