Growing Leek in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Yes, with the right inputs — Kisumu is moderately suited to Leek. Kisumu's soil (pH 5.54, slightly acidic) gives Leek a suitability score of 68/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

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. On ShambaIQ's soil-match model, Leek is the #57 soil match of the 106 crops we assess for Kisumu County. 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.

Bags per acre in Kisumu
0.50.4

Kisumu's nitrogen (0.91 g/kg) is 76% of the 1.2 g/kg Leek needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
