Growing Dhania in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Dhania, with a soil-match score of 68/100. At an average pH of 5.38 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 (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. Dhania prefers loam soils, while Nyandarua 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.
