Growing Cauliflower in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

Quick answer

Yes, with the right inputs — Kakamega is moderately suited to Cauliflower. Kakamega's soil (pH 5.63, slightly acidic) gives Cauliflower a suitability score of 57/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.

Cauliflower can be grown in Kakamega County, but the soil scores 57/100 and needs targeted management to reach full potential. At an average pH of 5.63 the soil is slightly acidic to near-neutral, below Cauliflower's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.01 g/kg, P 14 mg/kg, K 147 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Cauliflower, which favours loam. On ShambaIQ's soil-match model, Cauliflower is the #48 soil match of the 106 crops we assess for Kakamega County. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kakamega's 57/100 suitability a realistic target here is closer to 7,125 kg/acre (~KES 427,500/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.
