Growing Turmeric in Nakuru

Soil suitability analysis based on Nakuru's nutrient profile

Turmeric can be grown in Nakuru County, but the soil scores 55/100 and needs targeted management to reach full potential. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 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. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Nakuru'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.
