Growing Pixie Oranges in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa 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 7.96 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 0.61 g/kg, P 37.7 mg/kg, K 407 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. Garissa receives approximately 250 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.
