Growing Cauliflower in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Kitui County is a challenging environment for Cauliflower (soil-match score 24/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Cauliflower prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Cauliflower, which favours loam. Kitui receives approximately 500 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 Kitui's 24/100 suitability a realistic target here is closer to 3,000 kg/acre (~KES 180,000/acre) unless the constraints above are addressed.
