Growing Banana in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Banana can be grown in Trans Nzoia County, but the soil scores 58/100 and needs targeted management to reach full potential. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5–7 band Banana prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Banana's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Banana, which favours loam. At 1900 m, the county sits above Banana's preferred altitude ceiling of 1500 m, where frost risk and cold nights reduce the crop's productivity. Banana's full potential is about 12,000 kg/acre (~KES 144,000/acre at KES 12/kg), but at Trans Nzoia's 58/100 suitability a realistic target here is closer to 8,700 kg/acre (~KES 104,400/acre) unless the constraints above are addressed.
