Growing Dhania in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Possible but challenging — Vihiga is only marginally suited to Dhania. Vihiga's soil (pH 5.62, slightly acidic) gives Dhania a suitability score of 46/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Dhania can be grown in Vihiga County, but the soil scores 46/100 and needs targeted management to reach full potential. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Dhania's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Dhania, which favours loam. Dhania's full potential is about 1,500 kg/acre (~KES 112,500/acre at KES 75/kg), but at Vihiga's 46/100 suitability a realistic target here is closer to 862 kg/acre (~KES 64,650/acre) unless the constraints above are addressed.
