Growing Pixie Oranges in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Pixie Oranges. Turkana's soil (pH 7.95, alkaline) gives Pixie Oranges a suitability score of 2/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Pixie Oranges (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 7.95 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 0.41 g/kg, P 38.5 mg/kg, K 417 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. Turkana receives approximately 300 mm/year — well below Pixie Oranges's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Pixie Oranges is the #83 soil match of the 106 crops we assess for Turkana County. Pixie Oranges's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Turkana's 2/100 suitability a realistic target here is closer to 200 kg/acre (~KES 5,600/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 51% of the 0.8 g/kg Pixie Oranges needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
