WebMay 1, 2012 · Biological nitrogen (N) fixation is thought to be a major input of N in N-limited ecosystems. This study was set up to characterize the N 2 fixation of a copper (Cu) mine tailings abandoned since 1990 in Anhui Province, China. The soil N and N 2 fixation rates in six different sites including bare tailings (BT), algae crust (AC), algae-moss …
