Growing Avocado in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for Avocado (soil-match score 39/100) and will need significant amendment before planting. At an average pH of 6.55 the soil sits above Avocado's preferred 4.5–6.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 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. Kajiado receives approximately 500 mm/year — well below Avocado's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Kajiado's 39/100 suitability a realistic target here is closer to 2,925 kg/acre (~KES 52,650/acre) unless the constraints above are addressed.
