Jun 15, 2021 · Atmospheric nitrogen (N) deposition is a vital component of the global N cycle. Excessive N deposition on the Earth’s surface has adverse impacts on ecosystems and humans. Quantification of atmospheric N deposition is indispensable for assessing and addressing N deposition-induced environmental issues.

Jan 2, 2025 · Advances in manufacturing and trade have reshaped global nitrogen deposition patterns, yet their dynamics and drivers remain unclear. Here, we compile a comprehensive global nitrogen deposition...

Nitrogen (N) deposition describes the input of reactive nitrogen from the atmosphere to the biosphere both as gases, dry deposition and in precipitation as wet deposition.

In this paper, we isolate the effects of two environmental drivers, nitrogen (N) deposition and climate (temperature and precipitation) change, through an analysis of a single cohort of 24 dominant tree species. We assembled a tree database using data from U.S. Forest Service Forest Inventory and Analysis monitoring plots.

Accounting for organic nitrogen (ON) primary emissions, the present-day global nitrogen atmospheric source is about 60% anthropogenic, while total N deposition increases by about 20% relative to simulations without ON primary emissions.

Here, we use a large dataset of European grasslands along a gradient of nitrogen (N) deposition to show statistically significant declines in the abundance of species from the lowest level of N deposition at which it is possible to identify a change.

Jan 18, 2025 · Microbial processing of atmospheric nitrogen (N) deposition regulates the retention and mobilization of N in soils, with important implications for water quality.

Nitrogen deposition from the atmosphere can occur from gases (dry deposition) and in precipitation as wet deposition. Enhanced reactive N deposition is a consequence of global emissions from fossil fuel combustion and ammonia mainly from agricultural sources (Dignon and Hameed 1989). Nitrate can also be supplied from synthetic fertilisers.

Nitrogen deposition refers here to the deposition (wet and dry) of all nitrogen-containing gas phase chemical species resulting from NOx (NO + NO2) emissions. We show that under the assumed IPCC SRES A2 scenario the global annual average nitrogen deposition over land is expected to increase by a factor of $2.5, mostly because of the increase in ...

Feb 5, 2025 · Nitrogen deposition more likely stimulates methane emissions in natural wetlands by enhancing carbon substrates and methanogenic activities (39, 40), but the magnitude of its influence on future wetland methane emissions is likely to be controversial (39–41) and is complicated by runoff of nitrogen fertilizers from nearby cropland especially ...
