Growing Radish in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Kisumu County is a solid choice for Radish, with a soil-match score of 65/100. At an average pH of 5.54 the soil is slightly acidic to near-neutral, 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 (12.5 mg/kg) and potassium (166 mg/kg) all meet Radish's requirements, so a maintenance fertilizer programme is enough. Radish prefers sandy loam soils, while Kisumu is largely clay, 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 Kisumu's 65/100 suitability a realistic target here is closer to 6,500 kg/acre (~KES 260,000/acre) unless the constraints above are addressed.
