Description:... Loblolly pine (Pinus taeda 1.) trees were sampled to determine the effect of growth flush, crown position of pole trees, and winter temperature extremes upon the nutrient content of needles. Winter temperatures did not have an important influence upon elemental content. because concentrations of several elements differed for the first, second, and third growth flush of needles, needle samples should be collected in winter months from the previous spring's first flush near the top of the tree.
