Growing Dhania in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Dhania can be grown in Kirinyaga County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.31 the soil is moderately acidic, below Dhania's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.36 g/kg), phosphorus (12.5 mg/kg) and potassium (177 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. Dhania prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. 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.
