The pitcher plant Sarracenia purpurea can directly acquire organic nitrogen and short-circuit the inorganic nitrogen cycle. [PDF]
BACKGROUND:Despite the large stocks of organic nitrogen in soil, nitrogen availability limits plant growth in many terrestrial ecosystems because most plants take up only inorganic nitrogen, not organic nitrogen.

Nitrogen Deposition on Danish Nature [PDF]
Eutrophication events are frequent in Inner Danish waters and critical loads are exceeded for much of the Danish sensitive terrestrial ecosystems. The Danish air quality monitoring program combines measurements and model calculations to benefit from the ...

Atmospheric deposition of nitrogen to the Baltic Sea in the period 1995–2006 [PDF]
The EMEP/MSC-W model has been used to compute atmospheric nitrogen deposition into the Baltic Sea basin for the period of 12 yr: 1995–2006. The level of annual total nitrogen deposition into the Baltic Sea basin has changed from 230 Gg N in 1995 to 199 ...

Nitrogen Deposition Calculations for Europe [PDF]
Nitrogen deposition calculations for Europe were performed by separate models describing the long range transport of ammonia and oxidized nitrogen. Tests of model results against observations are briefly described.

Trends in the chemistry of atmospheric deposition and surface waters in the Lake Maggiore catchment [PDF]
The Lake Maggiore catchment is the area of Italy most affected by acid deposition. Trend analysis was performed on long-term (15-30 years) series of chemical analyses of atmospheric deposition, four small rivers draining forested catchments and four high

Effect of Nitrogen Deposition on Soil CO2 Emission During Freezing-Thawing Incubation Period [PDF]
Due to the traditional analysis method on the influence of soil nitrogen deposition on soil CO2 emissions during the freezing and thawing period, the initial impact of nitrogen deposition on soil CO2 emissions during the freezing and thawing incubation ...

Nitrogen deposition from aviation emissions
Excess nitrogen deposition from anthropogenic sources of atmospheric emissions, such as agriculture and transportation, can have negative effects on natural environments. Designing effective conservation efforts requires knowledge of the contribution of individual sectors.

Improvement of stomatal resistance and photosynthesis mechanism of Noah-MP-WDDM (v1.42) in simulation of NO2 dry deposition velocity in forests [PDF]
Rapid urbanisation and economic development in China have led to a dramatic increase in nitrogen oxide (NO2) emissions, causing serious atmospheric nitrogen pollution and relatively high levels of nitrogen deposition.

There have been few studies on the impact of nitrogen deposition on paddy field ecosystem; therefore, we evaluated the effects of different N deposition levels (0, 40, and 120 kg N·ha−1) with the conventional nitrogen rate (180 kg N·ha−1) on rice field ...

Global deposition of total reactive nitrogen oxides from 1996 to 2014 constrained with satellite observations of NO2 columns [PDF]
Reactive nitrogen oxides (NOy) are a major constituent of the nitrogen deposited from the atmosphere, but observational constraints on their deposition are limited by poor or nonexistent measurement coverage in many parts of the world.
