Growing Avocado in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Machakos County is a solid choice for Avocado, with a soil-match score of 65/100. At an average pH of 7.03 the soil sits above Avocado'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 Avocado's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Avocado, which favours sandy loam. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Machakos's 65/100 suitability a realistic target here is closer to 4,875 kg/acre (~KES 87,750/acre) unless the constraints above are addressed.
