Growing Dhania in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Dhania (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Dhania's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. Dhania prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 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.
