Growing Maize in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Quick answer

Yes, with the right inputs — Kakamega is moderately suited to Maize. Kakamega's soil (pH 5.63, slightly acidic) gives Maize a suitability score of 71/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.

Kakamega County is a solid choice for Maize, with a soil-match score of 71/100. Local soils average pH 5.63 — 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, phosphorus, and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Maize, which favours loam. On ShambaIQ's soil-match model, Maize is the #31 soil match of the 106 crops we assess for Kakamega County. Maize's full potential is about 1,800 kg/acre (~KES 81,000/acre at KES 45/kg), but at Kakamega's 71/100 suitability a realistic target here is closer to 1,598 kg/acre (~KES 71,910/acre) unless the constraints above are addressed.
