The fate of 15N-labeled ammonium and nitrate applied on trees canopy in a mature balsam-fir stand, Quebec
Canopy uptake of atmospherically deposited nitrogen (N) in N-limited boreal forests may represent an important source of N for growth. A tracer study was conducted by repeated applications of artificial precipitation with ambient inorganic N concentration (two treatments: 15N-NH4NO3 and NH415N-NO3,...
