Growing Celery in Meru
Soil suitability analysis based on Meru's nutrient profile
Meru County is a solid choice for Celery, with a soil-match score of 60/100. At an average pH of 4.88 the soil is strongly acidic, below Celery's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Celery's requirements, so a maintenance fertilizer programme is enough. 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 Meru's 60/100 suitability a realistic target here is closer to 9,000 kg/acre (~KES 630,000/acre) unless the constraints above are addressed.
