Growing Avocado in Lamu

Soil suitability analysis based on Lamu's nutrient profile

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. At current prices (about KES 18/kg) and a typical 2,000 kg/acre yield, a well-managed Avocado crop here can gross roughly KES 36,000 per acre.
