Growing Avocado in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Quick answer

Possible but challenging — Makueni is only marginally suited to Avocado. Makueni's soil (pH 7.5, alkaline) gives Avocado a suitability score of 42/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.

Makueni County is a challenging environment for Avocado (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 7.5 the soil sits above Avocado's preferred 4.5–6.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 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. On ShambaIQ's soil-match model, Avocado is the #69 soil match of the 106 crops we assess for Makueni County. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Makueni's 42/100 suitability a realistic target here is closer to 3,150 kg/acre (~KES 56,700/acre) unless the constraints above are addressed.

Better matched to Makueni's soil: Lucerne, Mango, and Sisal — each scores higher on the same soil.
