Growing Potato in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Possible but challenging — Kisumu is only marginally suited to Potato. Kisumu's soil (pH 5.54, slightly acidic) gives Potato a suitability score of 48/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.
Potato can be grown in Kisumu County, but the soil scores 48/100 and needs targeted management to reach full potential. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 4.8–6.5 band Potato 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. Potato prefers sandy loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Potato is the #88 soil match of the 106 crops we assess for Kisumu County. Potato's full potential is about 8,000 kg/acre (~KES 304,000/acre at KES 38/kg), but at Kisumu's 48/100 suitability a realistic target here is closer to 4,800 kg/acre (~KES 182,400/acre) unless the constraints above are addressed.
Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Kisumu's nitrogen (0.91 g/kg) is 76% of the 1.2 g/kg Potato needs, so the standard 1 bag/acre is raised to 1.25. Split it across two applications to limit leaching.
