Growing Turmeric in Bomet
Soil suitability analysis based on Bomet's nutrient profile
Yes, with the right inputs — Bomet is moderately suited to Turmeric. Bomet's soil (pH 6.02, slightly acidic) gives Turmeric a suitability score of 55/100. Match fertilizer to Bomet's nitrogen and phosphorus levels for the best result.
Turmeric can be grown in Bomet County, but the soil scores 55/100 and needs targeted management to reach full potential. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 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 1900 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 #76 soil match of the 106 crops we assess for Bomet County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Bomet's 55/100 suitability a realistic target here is closer to 4,125 kg/acre (~KES 330,000/acre) unless the constraints above are addressed.
Better matched to Bomet's soil: Wambugu Apples, Kale (Sukuma Wiki), and Garden Peas — each scores higher on the same soil.

Top dressing guide
Bomet's nitrogen (1.38 g/kg) already meets Turmeric's 1.2 g/kg requirement, so this is a maintenance rate.
