Growing Avocado in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Avocado (soil-match score 3/100) and will need significant amendment before planting. At an average pH of 6.76 the soil sits above Avocado's preferred 4.5–6.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is phosphorus and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 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 200 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 Kwale's 3/100 suitability a realistic target here is closer to 225 kg/acre (~KES 4,050/acre) unless the constraints above are addressed.
