Growing Broccoli in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Broccoli (soil-match score 8/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Broccoli 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 Broccoli, which favours loam. Kitui receives approximately 500 mm/year — well below Broccoli's minimum of 800 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 90/kg) and a typical 5,000 kg/acre yield, a well-managed Broccoli crop here can gross roughly KES 450,000 per acre.
