Growing Dhania in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Dhania (soil-match score 35/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 mg/kg against this crop's low/low/low demand — so the fertilizer plan below prioritises closing that deficit. Dhania prefers loam soils, while Isiolo is largely sandy, so drainage and organic-matter management matter more here. Isiolo receives approximately 350 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 Isiolo's 35/100 suitability a realistic target here is closer to 656 kg/acre (~KES 49,200/acre) unless the constraints above are addressed.
