Plot showing the average N2 fixation rates measured as 15N–N2 incorporation for incubation with 15N–N2 (left panel) and 15N–N2 + 13C–CH4 (right panel) displayed per fertilization treatment. Incubations were performed either in the dark (dark blue) or in the light (light blue). Error bars indicate SEM and light grey dots show raw data
