Growing Celery in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Celery, with a soil-match score of 61/100. At an average pH of 5.31 the soil is moderately acidic, 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 phosphorus and potassium — measured at N 1.36 g/kg, P 12.5 mg/kg, K 177 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Celery prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. Celery's full potential is about 12,000 kg/acre (~KES 840,000/acre at KES 70/kg), but at Kirinyaga's 61/100 suitability a realistic target here is closer to 9,150 kg/acre (~KES 640,500/acre) unless the constraints above are addressed.
