Growing Yams in Migori

Soil suitability analysis based on Migori's nutrient profile

Migori County is well suited to Yams, scoring 85/100 on ShambaIQ's soil-match model. At an average pH of 5.43 the soil is moderately acidic, below Yams's preferred 5.5–6.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 169 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Yams, which favours sandy loam. At current prices (about KES 80/kg) and a typical 6,000 kg/acre yield, a well-managed Yams crop here can gross roughly KES 480,000 per acre.
