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. Dhania's full potential is about 1,500 kg/acre (~KES 112,500/acre at KES 75/kg), but at Marsabit's 23/100 suitability a realistic target here is closer to 431 kg/acre (~KES 32,325/acre) unless the constraints above are addressed.
