Growing Wheat in Busia

Soil suitability analysis based on Busia's nutrient profile

Busia County is a challenging environment for Wheat (soil-match score 21/100) and will need significant amendment before planting. At an average pH of 5.29 the soil is moderately acidic, 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 16.6 mg/kg, K 175 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. At 1200 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 Busia's 21/100 suitability a realistic target here is closer to 525 kg/acre (~KES 26,250/acre) unless the constraints above are addressed.
