Growing Cauliflower in Kakamega

Soil suitability analysis based on Kakamega's nutrient profile

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. 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.
