Attenuation of Herbicides in Sub-Arctic Enviroments: Continental Climate Study

项目名称：	Attenuation of Herbicides in Sub-Arctic Enviroments: Continental Climate Study
摘要：	The purpose of this project is to investigate the environmental fate and attenuation of three herbicides currently being evaluated for use along Alaska's transportation corridors. Building upon results obtained in previous studies, this work seeks to contribute to the knowledge base necessary to minimize environmental risks associated with herbicide application in Alaska's sensitive, cold region ecosystems. As transportation-related entities such as the Alaska Department of Transportation & Public Facilities (ADOT&PF) and the Alaska Railroad Corporation (AKRR) require strict vegetation management practices in order to safely conduct operations, these entities have an interest in evaluating herbicides as a potential management tool. As a consequence, the AKRR (current study and previous study) and the ADOT (previous studies) are collaborating with the Alaska University Transportation Research Center (AUTC) to fund research efforts pursuant to herbicide application. In a current project joint funded by the AKRR and AUTC Razor® Pro and Oust® Extra were applied on two study plots near the southern section of AKRR rail line near Seward, Alaska. Soil and groundwater samples from each of these study plots are being analyzed for each herbicide over time. In the proposed study, Razor® Pro and Oust® Extra will be applied on the northern section of AKRR rail line near Fairbanks, Alaska. As in the ongoing study, researchers from the UAF Water & Environmental Research Center (WERC) will evaluate the fate of these herbicides over a two-year time period through a series of soil and groundwater samples in order to obtain site-specific attenuation data. As part of the current, lysimeters were installed at the UAF Fairbanks Experiment Farm to better quantify the attenuation of different herbicides that may possibly be used on Alaskan right-of-ways. These lysimeter studies will continue as part of this proposed project.
