Growing Wheat in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a challenging environment for Wheat (soil-match score 22/100) and will need significant amendment before planting. At an average pH of 5.54 the soil is slightly acidic to near-neutral, below Wheat'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 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. The county's predominantly clay soils suit Wheat, which favours clay. At 1150 m, the county sits below Wheat's preferred altitude range (1800–3000 m), which limits yield potential due to heat stress. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Kisumu's 22/100 suitability a realistic target here is closer to 550 kg/acre (~KES 27,500/acre) unless the constraints above are addressed.
