Growing Turmeric in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a solid choice for Turmeric, with a soil-match score of 68/100. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–7.5 band Turmeric prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Turmeric prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Turmeric's full potential is about 6,000 kg/acre (~KES 480,000/acre at KES 80/kg), but at Kisumu's 68/100 suitability a realistic target here is closer to 5,100 kg/acre (~KES 408,000/acre) unless the constraints above are addressed.
