Growing Cauliflower in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Wajir County is a challenging environment for Cauliflower (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Cauliflower's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Cauliflower prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Cauliflower's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Wajir's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
