Compositional nutrient diagnosis was used to evaluate the nutritional status of trees located in the Abitibi region of Quebec in order to determine the effects of species (white birch, conifer (balsam fir and white spruce), stand are (31, 51, 72, and 125 years) and parent material (lacustrine clay and glacial till) on foliar nutrient concentrations. Significant differences were found in foliar nutrient concentrations between the three species growing on similarly classified sites. The age of the stand significantly influenced the foliar nutrients of trees, illustrated by the significant decrease in foliar nitrogen concentration on clay and till and phosphorus concentrations on clay with stand age irrespective of species. Foliar nutrient concentrations varied significantly between parent materials. Trees of all species growing on clay stands exhibited deficiencies in nitrogen and conifers also exhibited severe deficiencies in magnesium. On till, deficiencies of potassium for birch, magnesium for conifer, and phosphorus for poplar were observed.
