N2 fixation and cycling in Alnus glutinosa, Betula pendula and Fagus sylvatica woodland exposed to free air CO2 enrichment

We measured the effect of elevated atmospheric CO on atmospheric nitrogen (N ) fixation in the tree species Alnus glutinosa growing in monoculture or in mixture with the non-N -fixing tree species Betula pendula and Fagus sylvatica. We addressed the hypotheses that (1) N fixation in A. glutinosa wil...
