Growing Radish in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Radish can be grown in Murang'a County, but the soil scores 57/100 and needs targeted management to reach full potential. At an average pH of 5.03 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 (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Radish's requirements, so a maintenance fertilizer programme is enough. Radish prefers sandy loam soils, while Murang'a 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 Murang'a's 57/100 suitability a realistic target here is closer to 5,700 kg/acre (~KES 228,000/acre) unless the constraints above are addressed.
