Growing Maize in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Yes — Kisumu is well suited to Maize. Kisumu's soil (pH 5.54, slightly acidic) gives Maize a suitability score of 75/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

Kisumu County is well suited to Maize, scoring 75/100 on ShambaIQ's soil-match model. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–7 band Maize prefers, so no lime is usually required. The main gap is nitrogen and phosphorus — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. Maize prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Maize is the #32 soil match of the 106 crops we assess for Kisumu County. At current prices (about KES 45/kg) and a typical 1,800 kg/acre yield, a well-managed Maize crop here can gross roughly KES 81,000 per acre.
