1 INTRODUCTION Humans add approximately threefold reactive nitrogen (N) into terrestrial ecosystems compared with natural sources, potentially increasing nitrification in soils (Bowles et al., 2018; Sutton et al., 2011). Nitrification is the key process controlling N losses, since it produces nitrate, which can be easily leached, or lost by denitrification as nitrous oxide and dinitrogen gas (Butterbach-Bahl et al., 2013).
