Variation in the major element content of red spruce foliage with season, crown position, tree and tissue age



Variation in the major element content of red spruce foliage with season, crown position, tree and tissue age



Communications in Soil Science and Plant Analysis 12(1): 39-49



Three age classes of red spruce were sampled and analysed to determine the variability in the major element content with seasonal and sampling part changes. Results show a definite seasonal pattern for each element. Levels of N, P, K and Mg are generally low in mid-summer and high in early spring and autumn, while Ca and ash contents show the reverse pattern. Variations in nutrient content occur with changes in tree age, sample crown position and tissue age.
