Growing Sweet Orange in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Sweet Orange can be grown in Kitui County, but the soil scores 58/100 and needs targeted management to reach full potential. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Sweet Orange prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Sweet Orange, which favours loam. Sweet Orange's full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Kitui's 58/100 suitability a realistic target here is closer to 8,700 kg/acre (~KES 435,000/acre) unless the constraints above are addressed.
