Rising atmospheric CO2 concentrations may alter the nitrogen (N) content of ecosystems by changing N inputs and N losses. but responses vary in field experiments. possibly because multiple mechanisms are at play. We measured N fixation and N losses in a subtropical oak woodland exposed to 11 years of elevated atmospheric CO2 concentrations. https://www.nacrack.com/flash-find-Orthofeet-Edgewater-Men-s-Athletic-Shoe-hot-choice/
