Growing Pixie Oranges in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Pixie Oranges (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Pixie Oranges's preferred 5.5–7.5 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 Pixie Oranges, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Pixie Oranges's minimum of 600 mm — so supplemental irrigation would be essential for this crop. Pixie Oranges's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/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.
