Growing Pixie Oranges in Isiolo
Soil suitability analysis based on Isiolo's nutrient profile
Generally not ideal — Isiolo is poorly suited to Pixie Oranges. Isiolo's soil (pH 7.83, alkaline) gives Pixie Oranges a suitability score of 17/100. Match fertilizer to Isiolo's nitrogen and phosphorus levels for the best result.
Isiolo County is a challenging environment for Pixie Oranges (soil-match score 17/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 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. Isiolo receives approximately 350 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 #62 soil match of the 106 crops we assess for Isiolo County. Pixie Oranges's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Isiolo's 17/100 suitability a realistic target here is closer to 1,700 kg/acre (~KES 47,600/acre) unless the constraints above are addressed.
Better matched to Isiolo's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Isiolo's nitrogen (0.46 g/kg) is 57% 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.
