Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

Vitousek et al. (1997a, b) published "Human Alteration of the Global Nitrogen Cycle" in Ecological Applications and a second article with the same title as an ESA Issues in Ecology publication. Both ...

Save guides, add subjects and pick up where you left off with your BBC account. Nitrogen gas makes up 78% of Earth’s atmosphere and is an essential element in amino acids and proteins.

Discover the fascinating world of nitrogen, from knuckle-cracking to agriculture, and the urgent need to address nitrous ...

In addition, the nitrogen cycle has direct links to climate change, for example through fluxes of nitrous oxide (N2O), a potent greenhouse gas with 300 times the global warming potential of CO2 and ...

In the nitrogen cycle, phytoplankton and other marine plants turn nitrate (NO 3) into organic nitrogen during photosynthesis. The organic nitrogen sinks into the deep ocean, where microbes "eat ...

Previous projects include developing open-path, quantum cascade laser-based atmospheric sensors and constraining the emissions of atmospheric ammonia, a precursor to PM2.5 and critical component of ...

These isotopomers of N 2 O can be used to probe sources and sinks in the global nitrogen cycle by identifying nitrification and denitrification processes in soils and water which are key in soil ...

Nutrient availability, particularly nitrogen, influenced this response ... and subtropical oceans by approximately 10%, with ...
