Growing Celery in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Celery (soil-match score 3/100) and will need significant amendment before planting. Local soils average pH 6.76 — 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 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Celery, which favours loam. At 200 m, the county sits below Celery's preferred altitude range (1000–2600 m), which limits yield potential due to heat stress. Celery's full potential is about 12,000 kg/acre (~KES 840,000/acre at KES 70/kg), but at Kwale's 3/100 suitability a realistic target here is closer to 450 kg/acre (~KES 31,500/acre) unless the constraints above are addressed.
