Growing Pineapple in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Machakos County is a challenging environment for Pineapple (soil-match score 32/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Pineapple's preferred 4.5–6.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Pineapple's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Pineapple, which favours sandy loam. Machakos receives approximately 700 mm/year — well below Pineapple's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 35/kg) and a typical 30,000 kg/acre yield, a well-managed Pineapple crop here can gross roughly KES 1,050,000 per acre.
