The relationships between insect capture, mineral nutrition (particularly nitrogen and phosphorus), and plant growth and reproduction have been investigated for numerous species. The relatively large diversity of organisms that can survive in the “pitchers” of some carnivorous plants also has been ...
For a typical T. testudinum stand, N2 fixation is estimated to be 100 to 500 kg N/hectare per year. Numbers of N2-fixing bacteria in the rhizosphere sediments were roughly 50 to 300 times more abundant than those in the nonrhizosphere sediments, and in both types of sediments were of ...
Marine ecosystems are frequently nitrogen-limited and therefore considered to be favourable niches for diazotrophic organisms21. Coastal seagrass beds, such as those inhabited by Codakia species, are areas of particularly high microbial nitrogen fixation activity14, as the plants' rhizosphere is densely ...
The nitrogen (N) cycle in terrestrial ecosystems is strongly influenced by resorption before litter fall and by mineralization after litter fall. Although both resorption and mineralization make N available to plants and are influenced by climate, their

3.1. The δ15N values of non-N2-fixing reference plants Various plant species of non-legume reference plants including (lettuce, White Swiss Chard Fordhook Giant, cabbage, nightshade and Bacon weed) were collected in the glasshouse where the groundnuts were grown. The δ15N values ranged from ...
About half of the nitrogen in our bodies today comes from bacteria via the enzyme nitrogenase, which converts, or "fixes," unreactive nitrogen gas in the atmosphere into a form that plants can use for growth. The other half is produced artificially throu
Most nitrogen-fixing bacteria do not excrete appreciable amounts of reduced nitrogen into the environment. This suggests that the nitrogen fixed by these bacteria is released only at cell lysis. This nitrogen is probably incorporated into large molecules that are difficult for plants to assimilate. ...
Plants uptake N as NO3−or NH4+, and in soils, NO3− is generally the predominant N form for plant uptake. Crops normally uptake more NO3− than NH4+. Through the process of mineralization, the N found in organic compounds is converted to NO3− or NH4+. The bacterial led process...
