The effects of long term nitrogen fertilization on forest soil respiration in a subalpine ecosystem in Rocky Mountain National Park
MetadataShow full item record
Anthropogenic activities contribute to increased levels of nitrogen deposition and elevated CO2 concentrations in terrestrial ecosystems. The response of soil respiration to nitrogen fertilization in an on going 18- year field nitrogen amendment study was conducted from July 2014 to October 2014. The focus of this study was to determine the effects of nitrogen fertilization on soil carbon cycling, via respiration. Our objectives were to (1) test the hypothesis that N additions would increase soil respiration in Rocky Mountain National Park, and (2) understand the impacts of N additions on carbon ...
