Growing Sugarcane in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Sugarcane (soil-match score 5/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Sugarcane prefers loam soils, while Isiolo is largely sandy, so drainage and organic-matter management matter more here. Isiolo receives approximately 350 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 Isiolo's 5/100 suitability a realistic target here is closer to 1,688 kg/acre (~KES 8,440/acre) unless the constraints above are addressed.
