Evaluating the balance between vertical diffusive nitrate supply and nitrogen fixation with reference to nitrate uptake in the eastern subtropical North Atlantic Ocean [PDF]
, 2013 The balance between N2 fixation and diffusive NO3− supply is a key determinant for assessing the importance of both processes for new production in subtropical waters.

Systemic regulation of soybean nodulation and nitrogen fixation by nitrogen via isoflavones
Frontiers in Plant Science, 2022 Nitrogen (N) inhibits soybean (Glycine max L.) nodulation and N2 fixation. Isoflavones secreted by soybean roots can stimulate signal transduction for symbiotic nodules, thus playing a key role in root nodule development and N2 fixation. The relationship

N2 Fixation by Plasma-Activated Processes
Joule, 2021 Summary Sustainable nitrogen fixation could offset the significant environmental and societal costs associated with the energy-intensive conventional Haber-Bosch process (HB). This perspective compares the energy requirements, CO2 emissions, and commodity prices associated with alternative plasma-activated ammonia synthesis to those for HB.

The conundrum of marine N2 fixation [PDF]
American Journal of Science, 2005 Over the last 30 years, immense progress has been made in understanding the global significance of marine nitrogen (N2) fixation. Development of enzymological, isotopic and molecular techniques for identifying N2 fixers and quantifying N2 fixation rates, as well as more frequent and extensive field campaigns have fuelled such progress.

Implicating the Role of Au-H Bonds in Photochemical N2 Fixation by Ruthenium Doped Gold Clusters
, 2023 Dinitrogen fixation through the Nitrogen Reduction Reaction (NRR) under mild conditions without the use of sacrificial agents has its share of formidable hurdles. It has been shown recently that Ru-doped Au nanoclusters can reduce N2 molecule to NH3 only

The amount but not the proportion of N2 fixation and transfers to neighboring plants varies across grassland soils [PDF]
, 2020 Biological nitrogen fixation (BNF) is an important nitrogen source for both N2-fixers and their neighboring plants in natural and managed ecosystems.

High numbers of Trichodesmium and diazotrophic diatoms in the southwest Indian Ocean [PDF]
, 2009 We observed high cell numbers of large (>50?m) nitrogen-fixing phytoplankton to the south and to the east of Madagascar in February 2005. The distribution of the diazotrophic taxa we found was markedly different: Trichodesmium was most abundant (500 ...

, 2023 Electrochemical N2 reduction reaction (NRR) has emerged as the most effective alternative to the conventional Haber-Bosch process for N2 fixation. Although NRR is only used in the synthesis of NH3, researchers have recently exploited it in Metal-N2 ...
