Growing Radish in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Kakamega County is a challenging environment for Radish (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 5.63 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. The main gap is potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Radish prefers sandy loam soils, while Kakamega is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Radish is the #81 soil match of the 106 crops we assess for Kakamega County. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Kakamega's 41/100 suitability a realistic target here is closer to 4,100 kg/acre (~KES 164,000/acre) unless the constraints above are addressed.

Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.
