Growing Avocado in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Avocado (soil-match score 10/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Avocado's preferred 4.5–6.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Avocado, which favours sandy loam. Samburu receives approximately 350 mm/year — well below Avocado's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Samburu's 10/100 suitability a realistic target here is closer to 750 kg/acre (~KES 13,500/acre) unless the constraints above are addressed.
