Growing Avocado in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Avocado (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 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 0.52 g/kg, P 39.3 mg/kg, K 396 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. Wajir receives approximately 200 mm/year — well below Avocado's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Avocado is the #82 soil match of the 106 crops we assess for Wajir County. Avocado's full potential is about 6,000 kg/acre (~KES 108,000/acre at KES 18/kg), but at Wajir's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
