Growing Pixie Oranges in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Tana River County is a challenging environment for Pixie Oranges (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.4 — 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 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Pixie Oranges, which favours sandy loam. Tana River receives approximately 400 mm/year — well below Pixie Oranges's minimum of 600 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 28/kg) and a typical 4,000 kg/acre yield, a well-managed Pixie Oranges crop here can gross roughly KES 112,000 per acre.
