Abstract

The extent to which greater net primary productivity (NPP) will be sustained as the atmospheric CO₂ concentration increases will depend, in part, on the long-term supply of N for plant growth. Over a two-year period, we used common field and laboratory methods to quantify microbial N, gross N mineralization, microbial N immobilization, and specific microbial N immobilization in three free-air CO₂ enrichment experiments (Duke Forest, Oak Ridge, Rhinelander).

Keywords
