Growing Parsley in Meru
Soil suitability analysis based on Meru's nutrient profile
Parsley can be grown in Meru County, but the soil scores 56/100 and needs targeted management to reach full potential. At an average pH of 4.88 the soil is strongly acidic, below Parsley'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 Parsley's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Parsley, which favours loam. Parsley's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Meru's 56/100 suitability a realistic target here is closer to 2,800 kg/acre (~KES 280,000/acre) unless the constraints above are addressed.
