Growing Cabbage in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a solid choice for Cabbage, with a soil-match score of 68/100. At an average pH of 4.88 the soil is strongly acidic, below Cabbage's preferred 5–7.5 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 Cabbage's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Cabbage, which favours clay loam. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Meru's 68/100 suitability a realistic target here is closer to 12,750 kg/acre (~KES 229,500/acre) unless the constraints above are addressed.
