Popis:	Monthly foliage samples were evaluated for elemental composition from red spruce and balsam fir trees in a commercial, low elevation spruce-fir stand at Howland, Maine during the 1987 growing season. Balsam fir showed consistently higher concentrations in A1 and to a lesser extent N, Ca, Mg, and Fe when compared to red spruce. Red spruce exhibited consistently higher Mn and K concentrations. Both species showed a marked seasonal trend in the foliar concentrations of N, P, K, and Ca in current year foliage. For N, P, and K current year foliar concentrations declined rapidly during the early part of the growing season. Calcium concentrations steadily increased during the growing season for both species and age class of needles. Foliar concentrations of N and P in both species suggests that the availability of these nutrients is limited for this site.
