Theses, Dissertations and Capstones
Many forested systems of the eastern US are becoming significantly nitrogen (N) saturated due to chronic N deposition from the atmosphere. Nitrogen saturation has the potential to alter important internal plant processes, such as nutrient cycling. While extensive research has been conducted on the responses of soil to N saturation, considerably less research has focused on the response of plant nutrient dynamics, nutrient concentrations, and nutrient ratios to excess N. Research was conducted on two watersheds at the Fernow Experimental Forest in West Virginia: WS3 (fertilized with ammonium sulfate annually since 1989) and WS7 (untreated control). Presenescent and senesced leaves …
