Influence of Soil Parent Material on the Nutrition and Health of Established Conifer Stands in theInland Northwest

Initial efforts of the Intermountain Forest Tree Nutrition Cooperative (IFTNC) concentrated on studying the effect of nitrogen fertilization on Douglas-fir (Psuedotsuga menziesii var. glauca) growing in the inland Northwest (eastern Oregon, eastern Washington, Idaho, and western Montana). The IFTNC established ninety-four experimental sites in managed, second growth Douglas-fir stands. This paper presents results showing that tree growth response to N fertilization and tree mortality rates are significantly influenced by the underlying rocks on which the stand is growing.
