Growing Leek in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a solid choice for Leek, with a soil-match score of 68/100. At an average pH of 5.54 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 and potassium — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Leek prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kisumu's 68/100 suitability a realistic target here is closer to 8,500 kg/acre (~KES 510,000/acre) unless the constraints above are addressed.
