Growing Leek in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Leek can be grown in Nyamira County, but the soil scores 55/100 and needs targeted management to reach full potential. At an average pH of 5.58 the soil is slightly acidic to near-neutral, below Leek's preferred 6–7.5 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 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Leek, which favours loam. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Nyamira's 55/100 suitability a realistic target here is closer to 6,875 kg/acre (~KES 412,500/acre) unless the constraints above are addressed.
