Growing Dhania in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Dhania (soil-match score 23/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Dhania's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (37.3 mg/kg) and potassium (420 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. Dhania prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Dhania's minimum of 500 mm — so supplemental irrigation would be essential for this crop. 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.
