Growing Pixie Oranges in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Quick answer

Generally not ideal — Kilifi is poorly suited to Pixie Oranges. Kilifi's soil (pH 6.24, slightly acidic) gives Pixie Oranges a suitability score of 2/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.

Kilifi County is a challenging environment for Pixie Oranges (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–7.5 band Pixie Oranges prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Pixie Oranges, which favours sandy loam. At 150 m, the county sits below Pixie Oranges's preferred altitude range (1000–2000 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Pixie Oranges is the #80 soil match of the 106 crops we assess for Kilifi County. Pixie Oranges's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Kilifi'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 Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.
