Abstract:The stem portion of the tree represents the nutrient capital removed in conventional harvesting systems. It also represents the nutrient capital immobilized in a stand. Accurate estimates of stem nutrient content are required to evaluate the forest nutrient cycle and harvesting impacts. This investigation suggests that a single stem disc, when used to estimate the nutrient content of a stem, does not estimate this content within +ACY-plusmn+ADs- 10 percent of the actual stem content. More than five discs, taken over the length of the stem, are needed to meet a 10 percent allowable error criterion. Forest Sci. 28:481-487.
