Growing Wambugu Apples in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Generally not ideal — Machakos is poorly suited to Wambugu Apples. Machakos's soil (pH 7.03, near-neutral) gives Wambugu Apples a suitability score of 20/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Machakos County is a challenging environment for Wambugu Apples (soil-match score 20/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Wambugu Apples's preferred 5–7 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 Wambugu Apples's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Wambugu Apples, which favours loam. Machakos receives approximately 700 mm/year — well below Wambugu Apples's minimum of 1000 mm — so supplemental irrigation would be essential for this crop. Wambugu Apples's full potential is about 4,000 kg/acre (~KES 300,000/acre at KES 75/kg), but at Machakos's 20/100 suitability a realistic target here is closer to 1,000 kg/acre (~KES 75,000/acre) unless the constraints above are addressed.
