Growing Turmeric in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Homa Bay County is a solid choice for Turmeric, with a soil-match score of 64/100. At an average pH of 5.27 the soil is moderately acidic, below Turmeric's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.05 g/kg, P 13.8 mg/kg, K 147 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. 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 Homa Bay's 64/100 suitability a realistic target here is closer to 4,800 kg/acre (~KES 384,000/acre) unless the constraints above are addressed.
