Soil pH and the levels of potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), and zinc (Zn) in the soil at the root surface and the surrounding soil were compared under healthy and citrus blight-affected orange trees at two locations. The feeder roots were also analyzed for these elenents. Potassium, Ca, and Mg were highest in the rhizosphere of blighted trees, with some, but lower accumulation around healthy roots. Potassium was higher and Fe, Mn, and Zn were lower in feeder roots of blighted than of healthy trees.
