Growing Avocado in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a challenging environment for Avocado (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.24 — 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 phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 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 50 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.
