Growing Turmeric in Kericho

Soil suitability analysis based on Kericho's nutrient profile

Turmeric can be grown in Kericho County, but the soil scores 49/100 and needs targeted management to reach full potential. Local soils average pH 5.94 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. Nitrogen (1.34 g/kg), phosphorus (23.7 mg/kg) and potassium (225 mg/kg) all meet Turmeric's requirements, so a maintenance fertilizer programme is enough. Turmeric prefers loam soils, while Kericho is largely clay, so drainage and organic-matter management matter more here. At 2000 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 #72 soil match of the 106 crops we assess for Kericho County. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Kericho's 49/100 suitability a realistic target here is closer to 3,675 kg/acre (~KES 294,000/acre) unless the constraints above are addressed.

Better matched to Kericho's soil: Kale (Sukuma Wiki), Sweet Potato, and Wambugu Apples — each scores higher on the same soil.
