Nitrogen (N2) fixation in oligotrophic surface waters is the main source of new nitrogen to the ocean1and has a key role in fuelling the biological carbon pump2. Oceanic N2fixation has been attributed almost exclusively to cyanobacteria, even though genes encoding nitrogenase, the enzyme that fix...
Our results suggest that marine nitrogen fixation is a ubiquitous process in the global ocean, and that UCYN-A is the keystone species for making it possible. This is a preview of subscription content, access via your institution Access options Access through your institution Access Nature and...
These topics include nitrogen fixation, both biological and abiotic; nitrogen pollution; reactive nitrogen, in the atmosphere and hydrosphere; the increasing human nitrogen footprint on the planet; the identification of nitrogen compounds in the marine environment; and the preservation of organic nitrogen...

and a subsample was oven dried at 105°C to a stable weight to calculate g soil/cm3. Average soil BNF rates from each plot were scaled up using the soil bulk density measured in that plot. Nitrogen fixation in the forest floor was scaled up using measured standing forest floor in each ...
Bacterial nitrogen fixation is the biological process by which atmospheric nitrogen is uptaken by bacteroids located in plant root nodules and converted into ammonium through the enzymatic activity of nitrogenase. In practice, this biological process serves as a natural form of fertilization and its opt...
In subject area: Earth and Planetary Sciences Nitrogen fixation is the process where atmospheric nitrogen is converted into a reactive form by breaking the triple covalent bond between nitrogen atoms, allowing it to bond with other elements like carbon, hydrogen, and oxygen through the use of speci...
