Growing Radish in Busia

Soil suitability analysis based on Busia's nutrient profile

Radish can be grown in Busia County, but the soil scores 54/100 and needs targeted management to reach full potential. At an average pH of 5.29 the soil is moderately acidic, below Radish's preferred 6–7.5 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 Radish's requirements, so a maintenance fertilizer programme is enough. Radish prefers sandy loam soils, while Busia is largely clay loam, so drainage and organic-matter management matter more here. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Busia's 54/100 suitability a realistic target here is closer to 5,400 kg/acre (~KES 216,000/acre) unless the constraints above are addressed.
