Abstract
A 2-year field study on rabbiteye blueberries (Vaccinium ashei Reade) growing on a Typic paleudult soil was conducted to compare the effects of soil S and soil or foliar micronutrient additions on plant growth and leaf plus soil elemental content.
Additions of S with either Mn chelate or a total micronutrient fertilizer increased Mn uptake.
Zn uptake was higher with foliar than soil applications of ZnSO4 and high leaf concentrations of Zn were positively correlated with plant chlorosis symptoms.
Sulfur additions reduced soil pH and % leaf Ca and Mg but had no independent influence on soil elemental content.
Two years after treatment initiation, chlorosis symptoms were decreased by soil S or by Fe, Mn, or total micronutrient additions.
