Growing Dhania in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Dhania (soil-match score 24/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Dhania's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/low/low demand — so the fertilizer plan below prioritises closing that deficit. Dhania prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana 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.
