Growing Celery in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Celery can be grown in Vihiga County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Celery's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Celery, which favours loam. Celery's full potential is about 12,000 kg/acre (~KES 840,000/acre at KES 70/kg), but at Vihiga's 58/100 suitability a realistic target here is closer to 8,700 kg/acre (~KES 609,000/acre) unless the constraints above are addressed.
