Growing Dhania in Tharaka Nithi
Soil suitability analysis based on Tharaka Nithi's nutrient profile
Tharaka Nithi County is a solid choice for Dhania, with a soil-match score of 64/100. At an average pH of 4.99 the soil is strongly acidic, below Dhania's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.23 g/kg), phosphorus (19.6 mg/kg) and potassium (211 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Dhania, which favours loam. At current prices (about KES 75/kg) and a typical 900 kg/acre yield, a well-managed Dhania crop here can gross roughly KES 67,500 per acre.
