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. Sugarcane's full potential is about 27,000 kg/acre (~KES 135,000/acre at KES 5/kg), but at Machakos's 31/100 suitability a realistic target here is closer to 10,463 kg/acre (~KES 52,315/acre) unless the constraints above are addressed.
