Growing Sugarcane in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Machakos County is a challenging environment for Sugarcane (soil-match score 31/100) 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 0.82 g/kg, P 31.4 mg/kg, K 338 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. Machakos receives approximately 700 mm/year — well below Sugarcane's minimum of 1100 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 5/kg) and a typical 27,000 kg/acre yield, a well-managed Sugarcane crop here can gross roughly KES 135,000 per acre.
