Growing Celery in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Celery (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 6–7.5 band Celery prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Celery prefers loam soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Tana River receives approximately 400 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 Tana River's 1/100 suitability a realistic target here is closer to 150 kg/acre (~KES 10,500/acre) unless the constraints above are addressed.
