Growing Wheat in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is a challenging environment for Wheat (soil-match score 24/100) and will need significant amendment before planting. At an average pH of 5.63 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, 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 Wheat, which favours clay. Wheat's full potential is about 2,000 kg/acre (~KES 100,000/acre at KES 50/kg), but at Kakamega's 24/100 suitability a realistic target here is closer to 600 kg/acre (~KES 30,000/acre) unless the constraints above are addressed.
