Growing Oats in Busia

Soil suitability analysis based on Busia's nutrient profile

Busia County is a challenging environment for Oats (soil-match score 28/100) and will need significant amendment before planting. At an average pH of 5.29 the soil is moderately acidic, below Oats's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 mg/kg) all meet Oats's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Oats, which favours loam. At 1200 m, the county sits below Oats's preferred altitude range (1800–3000 m), which limits yield potential due to heat stress. Oats's full potential is about 1,600 kg/acre (~KES 64,000/acre at KES 40/kg), but at Busia's 28/100 suitability a realistic target here is closer to 560 kg/acre (~KES 22,400/acre) unless the constraints above are addressed.
