Evaluating Sources for the page: Currently, there are only three references, two of which are correctly cited. Both correctly cited links work and are peer-reviewed sources. In one point in the article, in the “history of iron cycling on Earth” section, it even says ‘citation needed’ in the published Wikipedia article. There should be many more sources and links throughout the article both connecting to other Wikipedia pages (for example, ‘oxidation state’ is an extremely detailed Wikipedia page that would be a very useful link to include) as well as more science web pages and peer-reviewed citations.

Planned change of the iron cycle primary image

For a class assignment I will be updating the primary image of the iron cycle used for this page. My proposed improvements include adding detail to both the visual and non-visual informational content. I plan to include reservoir and flux values to indicate the abundance and movement of iron in different positions of the cycle. I will also include more constituents that are involved in iron cycling. To do so I will utilize multiple sources and provide links that are unlikely to become inactive, opposed to the one non-functional link for current image.--BeccaMGM (talk) 03:00, 16 February 2019 (UTC)

Reduction and oxidation reversed?

In the following quoted paragraph, immediately preceeding the subheading also quoted, I believe the word "oxidized," describing the transition from NH3- to NH2-, N2, etc., should be "reduced." Conversely, the subsequent use of "reduced" to describe the transition from Fe(II) to Fe(III) should be "oxidized." Present text:

" In anoxic conditions, Fe(II) can donate an electron that is accepted by N03− which is oxidized to several different forms of nitrogen compounds, NO2−, N20, N2, and NH4+, while Fe(II) is reduced to Fe(III).
