Growing Dhania in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Dhania. Garissa's soil (pH 7.96, alkaline) gives Dhania a suitability score of 18/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Dhania (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Dhania's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.61 g/kg), phosphorus (37.7 mg/kg) and potassium (407 mg/kg) all meet Dhania's requirements, so a maintenance fertilizer programme is enough. Dhania prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Dhania's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Dhania is the #17 soil match of the 106 crops we assess for Garissa County. Dhania's full potential is about 1,500 kg/acre (~KES 112,500/acre at KES 75/kg), but at Garissa's 18/100 suitability a realistic target here is closer to 338 kg/acre (~KES 25,350/acre) unless the constraints above are addressed.
Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Garissa's nitrogen reads 0.61 g/kg, but the rate stays at zero: Dhania is not top-dressed, for the crop-specific reason above.
