The foliar incorporation of various reactive forms of nitrogen (N) has been identified and
studied for nearly 30 years. However, the ecosystem-level ramifications of this uptake …

Controlled field experiments to study the effects of heightened atmospheric inputs of
nitrogen (N) to forests typically demonstrate that most N enters nonextractable pools in soil …

It is hypothesized that decreasing mean annual temperature and rates of nitrogen (N)
cycling causes plants to switch from inorganic to organic forms of N as the primary mode of …

Temperate forest 15N isotope trace experiments find nitrogen (N) addition‐driven carbon (C)
uptake is modest as little additional N is acquired by trees; however, several correlations of …

Nitrogen (N) deposition is impacting the services that ecosystems provide to humanity.
However, the mechanisms determining impacts on the N cycle are not fully understood. To …

This paper considers whether new problems are arising in forest ecosystems due to
increased levels of inorganic N deposition from the atmosphere, or whether there are no …

Nitrogen (N) is an essential nutrient that is highly abundant as N2 in the atmosphere and
also as various mineral and organic forms in soils. However, soil N bioavailability often limits …

Summary 1 Plant functional composition may indirectly affect fine root processes both
qualitatively (eg by influencing root chemistry) and quantitatively (eg by influencing root …

Nutrient resorption from senescing leaves is an important process of internal nutrient cycling
in plants, but the patterns of nutrient resorption and the coupled relationship between …

Effects of anthropogenic nitrogen (N) deposition and the ability of terrestrial ecosystems to
store carbon (C) depend in part on the amount of N retained in the system and its …
