The Contamination of Commercial (15)N(2) Gas Stocks with (15)N–Labeled Nitrate and Ammonium and Consequences for Nitrogen Fixation Measurements
We report on the contamination of commercial 15-nitrogen ((15)N) N(2) gas stocks with (15)N-enriched ammonium, nitrate and/or nitrite, and nitrous oxide. (15)N(2) gas is used to estimate N(2) fixation rates from incubations of environmental samples by monitoring the incorporation of isotopically lab...
