Growing Turmeric in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Quick answer

Possible but challenging — Uasin Gishu is only marginally suited to Turmeric. Uasin Gishu's soil (pH 6.39, slightly acidic) gives Turmeric a suitability score of 47/100. Match fertilizer to Uasin Gishu's nitrogen and phosphorus levels for the best result.

Turmeric can be grown in Uasin Gishu County, but the soil scores 47/100 and needs targeted management to reach full potential. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Turmeric's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Turmeric, which favours loam. At 2100 m, the county sits above Turmeric's preferred altitude ceiling of 1500 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Turmeric is the #87 soil match of the 106 crops we assess for Uasin Gishu County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Uasin Gishu's 47/100 suitability a realistic target here is closer to 3,525 kg/acre (~KES 282,000/acre) unless the constraints above are addressed.

Better matched to Uasin Gishu's soil: Beans, Snow Peas, and Napier Grass — each scores higher on the same soil.
