Short summary
Nitrogen availability influences ecosystem properties and limits productivity in much of the world. We compared a variety of proxies used to assess nitrogen status to see if they provide consistent indications of nitrogen availability. We found that although terrestrial metrics correlated with one another, terrestrial and water-based metrics were not correlated. Given that many authors have suggested these proxies give insight into ecosystem nitrogen status, this result merits further research.
