Growing Cauliflower in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Cauliflower can be grown in Kisumu County, but the soil scores 57/100 and needs targeted management to reach full potential. At an average pH of 5.54 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 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Cauliflower prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kisumu'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.
