Biological N2 Fixation in wetland rice fields: Estimation and contribution to nitrogen balance
This paper 1) reviews improvements and new approaches in methodologies for estimating biological N2 fixation (BNF) in wetland soils, 2) summarizes earlier quantitative estimates and recent data, and 3) discusses the contribution of BNF to N balance in wetland-rice culture.

Variation in symbiotic N2 fixation rates among Sphagnum mosses.
Biological nitrogen (N) fixation is an important process supporting primary production in ecosystems, especially in those where N availability is limiting growth, such as peatlands and boreal forests.

Nitrogenases in Oxygen Minimum Zone Waters
Biological dinitrogen (N2) fixation is the pathway making the large pool of atmospheric N2 available to marine life. Besides direct rate measurements, a common approach to explore the potential for N2 fixation in the ocean is a screening-based targeting ...

Productivity and biological N2-fixation in cereal-cowpea intercropping systems in sub-Saharan Africa. A review [PDF]
Intercropping is a common practice among farmers in sub-Saharan Africa, regarded as a sustainable way of improving land productivity to meet food and nutritional requirements for a growing population, especially in marginal areas. Cowpea (Vigna unguiculata L.

Planktonic Aggregates as Hotspots for Heterotrophic Diazotrophy: The Plot Thickens
Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments.

A Molecular-Level Mechanism of the Biological N2 Fixation
We present a detailed molecular-level mechanism for the biological fixation of atmospheric nitrogen into ammonia. The mechanism is based on a series of electronic structure calculations and provides insight into the key question of what it is that the enzyme does to enable selective N 2 reduction ...

Improving Biological Nitrogen Fixation to Improve Soil Nutrient Status
The chemical reduction of atmospheric nitrogen (N2) by hydrogen for incorporation into plant tissue is known as N fixation. Along with the carbon, N has a role in maintaining the optimum source and sink ratio, which ensures crop growth and biological ...

Heterogeneity of nitrogen fixation in the mesopelagic zone of the South China Sea
Biological dinitrogen (N2) fixation, the energetically expensive conversion of N2 gas to ammonia, plays an essential role in balancing the nitrogen budget in the ocean.

Endophytic Fungus Drives Nodulation and N2 Fixation Attributable to Specific Root Exudates
Endophytic fungi play important roles in the modification of ecosystem productivity; however, the underlying mechanisms are only partly understood. A 2-year field plot experiment verified that the endophytic fungus Phomopsis liquidambaris increased ...
