Biological N2 Fixation in the Upwelling Region off NW Iberia: Magnitude, Relevance, and Players [PDF]
Frontiers in Marine Science, 2017 The classical paradigm about marine N2 fixation establishes that this process is mainly constrained to nitrogen-poor tropical and subtropical regions, and sustained by the colonial cyanobacterium Trichodesmium spp.

Soybean yield, biological N2 fixation and seed composition responses to additional inoculation in the United States. [PDF]
Sci Rep, 2019 It is unclear if additional inoculation with Bradyrhizobia at varying soybean [Glycine max (L.) Merr.] growth stages can impact biological nitrogen fixation (BNF), increase yield and improve seed composition [protein, oil, and amino acid (AA ...

Productivity and biological N2-fixation in cereal-cowpea intercropping systems in sub-Saharan Africa. A review [PDF]
Agronomy for Sustainable Development, 2020 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.

15N2 as a tracer of biological N2 fixation: A 75-year retrospective [PDF]
Soil Biology and Biochemistry, 2017 15 N 2 has played a crucial role in fundamental studies of biological N 2 fixation. However, due to operational constraints, it has more often served as a qualitative rather than a quantitative tracer of biologically-fixed N (BFN).

Projecting global biological N2 fixation under climate warming across land and ocean.
Trends in MicrobiologyBiological N2 fixation sustains the global inventory of nitrogenous nutrients essential for the productivity of terrestrial and marine ecosystems. Like most metabolic processes, rates of biological N2 fixation vary strongly with temperature, making it ...

A Molecular-Level Mechanism of the Biological N2 Fixation
, 2019 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 ...

Biological N2 Fixation in wetland rice fields: Estimation and contribution to nitrogen balance
Plant and Soil, 1992 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.

Biological N2-fixation and its management in wetland rice cultivation
Fertilizer Research, 1995 The review summarizes the current status of the utilization of N2-fixing organisms as biofertilizer in rice cultivation. Heterotrophic bacteria, free-living cyanobacteria, Azolla, and legume green manures are considered with regard to their potential for increasing yield, their current use and the prospects for their use with regard to the identified ...
