Impact of Atmospheric Nitrogen Deposition on Carbon Storage Pathways along a Nitrogen Deposition Gradient in Coastal Sage Scrub Soils
Recent studies suggest that nitrogen can have significant effects on microbial activity and carbon storage by causing shifts in fungal:bacterial activity such that bacterial degradation pathways become dominant under high nitrogen conditions. If true, changes in fungal:bacterial (F:B) ratios could have a major impact on carbon storage in urban pollution affected soils that receive high amounts ...
متن کاملChinese coastal seas are facing heavy atmospheric nitrogen deposition
As the amount of reactive nitrogen (N) generated and emitted increases the amount of N deposition and its contribution to eutrophication or harmful algal blooms in the coastal zones are becoming issues of environmental concern. To quantify N deposition in coastal seas of China we selected six typical coastal sites from North to South in 2011. Concentrations of NH3, HNO3, NO2, particulate NH4 + ...
متن کاملAtmospheric nitrogen deposition promotes carbon loss from peat bogs.
Peat bogs have historically represented exceptional carbon (C) sinks because of their extremely low decomposition rates and consequent accumulation of plant remnants as peat. Among the factors favoring that peat accumulation, a major role is played by the chemical quality of plant litter itself, which is poor in nutrients and characterized by polyphenols with a strong inhibitory effect on micro...
متن کاملAtmospheric Nitrogen Deposition to the New Jersey Coastal Waters and Its Implications
In situ measurements of atmospheric NO3 and NH4 þ at Sandy Hook on the northern New Jersey (USA) coast and at Tuckerton on the southern New Jersey coast reveal significant temporal and spatial variations of these inorganic N constituents. The mean concentration of NO3 in precipitation was higher at Sandy Hook (44.6 lmol/L) than at Tuckerton (29.1 lmol/L). The mean concentration of NH4 þ in prec...
متن کاملEstimating direct and episodic atmospheric nitrogen deposition to a coastal waterbody.
Direct deposition of atmospheric nitrogen to shallow coastal embayments is usually estimated, since insufficient field measurements are available. Using Waquoit Bay (Cape Cod, MA. USA) as a case study, and a recent review of literature, we determined reasonable bounds on wet and dry inputs of inorganic and organic N. Since precipitation and wind vary daily, we explored the potential of episodic...
