Untitled[edit]

Nitrogen can also be artificially fixed for use in fertilizer, explosives, or in other products. The most popular method is by the Haber process. This artificial fertilizer production has achieved such scale that it is now the largest source of fixed nitrogen in the Earth's ecosystem.

I can't find a source for this claim, and it seems doubtful. Jfbolus (talk) 02:01, 14 April 2009 (UTC)

I know for a fact that this is the case - I will try and find a citation - it should be pretty easy. Smartse (talk) 12:09, 16 April 2009 (UTC)
Done. Thanks for pointing that out. Smartse (talk) 12:26, 16 April 2009 (UTC)

Proposed merger of Nitrate fixation[edit]

It seems pretty obvious that the Nitrate fixation page-let is actually about N2 ie. nitrogen and not about 'NO3 fixation.' I suggest the 'Nitrate fixation' page be deleted. Satyrium 15:11, 5 September 2006 (UTC)


This article would be much more useful to non-biologists if the list of nitrogen-fixing plants included the common names of those plants.

This article would be more useful if it mention what is the goal of doing nitrogen fixation... —Preceding unsigned comment added by 217.132.234.203 (talk) 09:05, 27 February 2008 (UTC)

There is a lot of unnecessarily complicated language in this article, aside from linked terminology or special jargon. It could be greatly simplified. —Preceding unsigned comment added by Smurfsahoy (talkcontribs) 22:05, 25 February 2009 (UTC)

Nitrogen fixing Archaebacteria[edit]

From what I could see, references 2 and 3 in the Wiki article do not speak about nitrogen fixation in Archaea. N2 fixation by mesophilic Archaea is until now only speculation. It is known, however, that some thermophilic archaeon can fix atmospheric N2 reference 1 and reference 2 and reference 3 and reference 4. The mechanism of N2 fixation was found to be essentially similar to what is found in bacteria reference 5 reference 6

Combustion[edit]

N fixation by combustion is mentioned in the introduction but not in the article. Smartse (talk) 12:20, 16 April 2009 (UTC)

Rubus[edit]

I've read elsewhere that a few Rubus species can do this too, e.g., Rubus ellipticus. Horatio (talk) 09:04, 12 September 2009 (UTC)

Definition issue[edit]

First sentence: "Nitrogen fixation is a process, biological, abiotic, or synthetic by which nitrogen (N2) in the atmosphere is converted into ammonia (NH3)." Later in the lead: "Nitrogen fixation also refers to other biological conversions of nitrogen, such as its conversion to nitrogen dioxide."

But this would exclude things like lightning creating NO2 (that's not a "biological" conversion), which IS called 'nitrogen fixation'. Really the term seems to be applied for anything that converts atmospheric N2 to nitrogen compounds (I've seen it applied to NOx production in general), though the specific biological def. is probably the more common context.

I think the first sentence should read: "Nitrogen fixation is a process, biological, abiotic, or synthetic, by which nitrogen (N2) in the atmosphere is converted into nitrogen compounds such as ammonia (NH3)." This would make the "also refers to" unnecessary while still mentioning ammonia. Vultur (talk) 22:40, 30 March 2012 (UTC)
