Growing Sugarcane in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Sugarcane (soil-match score 15/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Sugarcane's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. 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/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Sugarcane, which favours loam. Kitui receives approximately 500 mm/year — well below Sugarcane's minimum of 1100 mm — so supplemental irrigation would be essential for this crop. Sugarcane's full potential is about 27,000 kg/acre (~KES 135,000/acre at KES 5/kg), but at Kitui's 15/100 suitability a realistic target here is closer to 5,063 kg/acre (~KES 25,315/acre) unless the constraints above are addressed.
