Growing Ginger in Meru
Soil suitability analysis based on Meru's nutrient profile
Meru County is a solid choice for Ginger, with a soil-match score of 61/100. At an average pH of 4.88 the soil is strongly acidic, below Ginger's preferred 5.5–7 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 Ginger's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Ginger, which favours sandy loam. At current prices (about KES 200/kg) and a typical 6,000 kg/acre yield, a well-managed Ginger crop here can gross roughly KES 1,200,000 per acre.
