I just have a quick question regarding my textbook. In my textbook, it says that during nitrogen fixation the nitrogen gas found in air is converted to ammonium ions which can then be used by the plant but then it says during nitrification the ammonium ions are converted to nitrates so that they can be used by plants.

If the plant can use ammonium ions then why would they need to be converted to nitrate ions which can then be used by plants?

  • $\begingroup$ Do not post images of text! They discriminate against people with sight problems and cannot be indexed by the system. You must quote and provide the name of the text. And the only way I interpret a “quick” question is that is was written without sufficient research, or that you are hoping for a quick answer. The first would not reflect well on you, and the second would conflict with the policy of this site to provide authoritative answers. $\endgroup$ – David Mar 11 '19 at 19:49
