Growing Dragon Fruit in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Dragon Fruit (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Dragon Fruit's preferred 5.5–7 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 Dragon Fruit, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Dragon Fruit's minimum of 500 mm — so supplemental irrigation would be essential for this crop. Dragon Fruit's full potential is about 5,000 kg/acre (~KES 2,500,000/acre at KES 500/kg), but at Wajir's 8/100 suitability a realistic target here is closer to 500 kg/acre (~KES 250,000/acre) unless the constraints above are addressed.
