Growing Turmeric in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Turmeric can be grown in Nandi County, but the soil scores 56/100 and needs targeted management to reach full potential. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 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. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Nandi's 56/100 suitability a realistic target here is closer to 4,200 kg/acre (~KES 336,000/acre) unless the constraints above are addressed.
