Growing Avocado in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Kilifi County is a challenging environment for Avocado (soil-match score 2/100) 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 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Avocado, which favours sandy loam. At 150 m, the county sits below Avocado's preferred altitude range (1000–2200 m), which limits yield potential due to heat stress. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Kilifi's 2/100 suitability a realistic target here is closer to 150 kg/acre (~KES 2,700/acre) unless the constraints above are addressed.
