Significance of Nitrogen Cycle Nitrogen Cycle Key Terms References Steps of Nitrogen Cycle 1. Nitrogen Fixation The first stage in the nitrogen cycle is the reduction of N2gas to ammonia, a process called nitrogen fixation. The process of converting atmospheric N2gas into ammonia is carried out by...
Nitrogen fixation has also been correlated positively with concentrations ofDONoccurring in the water (Horne and Fogg, 1970;Horne et al., 1972;Paerl, 1985). Algae and Cyanobacteria release extracellularly many simple and complexorganic carbonand nitrogen compounds. Heterotrophic bacteria colonize common...

It is the mechanism through which certain plants transform atmospheric nitrogen gas into nitrogen that the plant can use to thriv...

It remains questionable, however, whether the symbiont gains any advantage from this association in evolutionary terms11. Biological nitrogen fixation (diazotrophy) is the conversion of molecular nitrogen (N2) into ammonia14. It provides the basis for the biosynthesis of organic nitrogen compounds and...
Nitrogen fixation is the primary source of reactive nitrogen in the ocean. Most ecological models do not predict nitrogen fixation in the Antarctic Ocean because of the low availability of iron and high abundance of nitrogen. Here we extensively examined nitrogen fixation in the Antarctic Ocean, and...
Nitrogen fixation is carried out naturally in soil by microorganisms termed diazotrophs that include bacteria such as Azotobacter and archaea. Some nitrogen-fixing
Free-living nitrogen fixation (FNF) is a ubiquitous phenomenon that plays a modest role in the (N) economy of an ecosystem. However, sampling difficulties, methodological constraints and environmental controls have presented challenges for predicting the actual rate of FNF. Therefore, a deeper underst...
Interest in growing legume green manures (LGMs) in synthetically-fertilized systems is increasing in the northern Great Plains of North America, partly due to the N-fixing capabilities of legumes; however, little is known about the effects of planting and termination time on N fixation amounts ...
Mimosa bimucronata originates from tropical America and exhibits distinctive leaf movement characterized by a relative slow speed. Additionally, this species possesses the ability to fix nitrogen. Despite these intriguing traits, comprehensive studies ha
