Growing Avocado in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Quick answer

Generally not ideal — Lamu is poorly suited to Avocado. Lamu's soil (pH 6.31, slightly acidic) gives Avocado a suitability score of 0/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.

Lamu County is a challenging environment for Avocado (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 4.5–6.5 band Avocado prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Avocado, which favours sandy loam. At 10 m, the county sits below Avocado's preferred altitude range (1000–2200 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Avocado is the #67 soil match of the 106 crops we assess for Lamu County. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Lamu's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Lamu's soil: Sesame (Simsim), Sorghum, and Cowpeas — each scores higher on the same soil.
