Talk:Flooded Soils

One minor thing, the picture of "schematic presentation of flooded soil" looks blurry. Is there anyway to make it clear?? Feili 15:59, 22 March 2008 (UTC)

I am impressed by your work that has done on this page!!! I have to say this page is well done!Feili 15:46, 22 March 2008 (UTC)

Although many microbes related to our topic are aleady in this site, I made a new Desulfococcus page. Please feel free to add somthing on Desulfococcus page.. And, our group will answer/adjust for your suggestions up to the end of this quarter. Sungho 04:26, 17 March 2008 (UTC)

Could you give more details in Current research part? The present "current research " looks similiar to the reference.

If we have to detail information in this page, we might be supposed to make a new page because current research is too wide to show only in one page. What our group wants is to show essential information about flooded soil. So, we don’t want to put more stories into now page. Thanks Sungho 22:22, 22 March 2008 (UTC)

Hi group! In the gleying section or our page, I'm wondering if we should also include manganese as a cause for black color in soil since we mention it there? I'm not sure who from our group did that part...Just a thought, Heather Thanks you Heather.. I added more information for MnO2.Sungho 22:22, 22 March 2008 (UTC)

You guys have some spelling errors toward the end of your page that you might want to check on. I was confused by this statement: "Although the energy production rate by fermentation is less efficient rather than oxidative phosphorylation..." Are you contrasting substrate-level phosphorylation and oxidative phosphorylation? Maybe you could explain that fermentation only involves substrate-level phosphorylation while aerobic respiration involves both substrate-level and oxidative phosphorylation (e- transport chain). This may better explain the difference in ATP yield. Good work! Jmmullane 06:43, 15 March 2008 (UTC)

Oxidative phosphorylation might confuse you. I want to change oxidative phosphorylation to just respiration. In general, oxidative phosphorylation indicate respiration reaction(both aerobic and anaerobic respiration). oxidative .... is not involved in fermentation as you said so that I was thinking when I mentioned just oxidative phosphorylation, you can notice that means respiration. And what we want to emphasize is not comparing the energy production rate but the importance of products of fermentation as substrates for anaerobic microbes. Thanks..Sungho 22:22, 22 March 2008 (UTC)

I had some issues with the size of my pictures too. You may want to save the picture to your computer and resize it using photoshop or something and then re-upload the file to the site. Then just replace the old file name with the new one in your image link. It worked for me, so hopefully that will help you guys. Jmmullane 06:17, 15 March 2008 (UTC)

Hi guys, I'm not sure what happened, but I was editing some images on our site and the gleying picture got a little out of control and I can't seem to shrink it back down. I'm not sure what the problem is...Please help! Sorry, it's weird, I don't even think I was in that section when it became enlarged...-Heather

Hey group! I created a page for microbe family Enterobacteriaceae, with a link to this in the nitrate reducing section of our page. Please check out this page and contribute as best you can if you're so inspired. It's an ok start. By the way, you guys are the dream team! Our page is supercalifragilisticexpealedoceous!!!! Special thanks to whoever fixed my images- I'm technologically challenged -Heather

Hey Sungho! I added two beautiful (and ginormous) pics to our site. Do you have ideas on resizing these images? It would be great if you could help with this part. Thanks a lot! Heather

You page was really helpful tool I even used it for my lab! I think the visuals bring a lot to the understanding. I didn't see any new studies though. [user bhsparks]

I really liked all the visuals! It's a nice change. I like the suggestion of the person below me about the Winogradsky column..maybe that could be one more picture to add if you can find it--I think that demonstrates the electron tower really well. The electron tower section was a little hard to follow...maybe try reorganizing the paragraph? An outside link to another site on electron tower theory might help, too. Great job!

I'd love to see a "Current Research" section that highlights some of the recent findings. Also, a "Monitoring" section would be great in order to show different ways in the laboratory or in the environment that one can monitor a flooded soil environment. For example, in lab we compared flooded soil over a duration of time, but we could achieve the same results by observing the changes that occur with depth in the Winogradsky columns. Kate Scow had a great visual in her powerpoint slides that compared the two methods, which may be a nice addition to your page. Other than that, this page is incredibly well-done!

A few minor things- the "Recover from flooded soils" section is missing text and the spacing between sections is huge in some spots. You say, "When soil is saturated with water, pH drops at first due to organic acid produced from fermentation. Then, pH gradually starts to rise because H+ is consumed via respiration of the aerobes and anaerobes." ---> Is this true that aerobic respiration is prevalent in flooded soils, or is it predominantly anaerobic respiration that rebounds the pH? I can see some aerobic processes happening at the surface, but is significant O2 diffusion occurring?

Did I miss your current research section? Other than that, I absolutely love all the visuals! They really break up the monotony of the text. Your page really reinforces the concepts of the class and the lab. Kudos to you! Jmmullane 06:16, 14 March 2008 (UTC)

IMO, get rid of the overwatered pot plant, probably not a good look for the page:-( but I like the ambition.Pbwebb 05:21, 14 March 2008 (UTC)

In your Processes section, you say "Through this variation of soil condition, various gases are emitted into the atmosphere or environmental factors, such as redox..." To me it would make more sense if you changed the "or" to an "and", as in: Through this variation of soil condition, various gases are emitted into the atmosphere and environmental factors, such as redox...)Njblackburn 05:01, 14 March 2008 (UTC)

I like the page! I would like to see a link to the carbon cycle page where you mention greenhouse gases in the intro, though (I did the carbon cycle page, so of course I would)Njblackburn 04:55, 14 March 2008 (UTC)

Very nice job people. As others have said, looks good, especially with the pictures (visuals always help people understand better in my opinion). There are only a few things that I want to suggest. In terms of linking to other sites, I'm not sure if any of you know or maybe someone else in the class does, but is there any way to link to regular wikipedia directly without having to use the URL? I was thinking it would be nice to put links to things like pH, soil aggregates, and other such things for people to click on if they don't know much about them. I was also thinking that maybe there is some way to link within your own page so that when you say "see electron tower theory" you can click that to go to that section. I looked a bit on the help and also just within other pages but I didn't see anything. In terms of content I didn't read everything thoroughly, but i felt a bit confused by the "electron tower" section. I understood it because I have learned it in this class, but I was thinking in terms of someone first being introduced to it the content might not be broken down in a logical way. Also, when you were discussing pH changes in flooded soils I remember Kate saying something like "pH rises after initial drop due to carbonate production that buffers." That might be something to include. Anyways, take it or leave it, that's my thoughts. Great work.Kjmuzikar 00:18, 14 March 2008 (UTC)

Very awesome site. The pictures are a bit small, however. And perhaps I didn't catch it, but did you ever mention the color change that occurs with flooded soils? Soils kept in anaerobic conditions get this cool gleyed color; a blue tint to them. Anyways, just a thought. Great job though! Lots of interesting information! Leslie Peacock 11:54, 13 March 2008 (UTC)

Thanks..You can see gleying soil.Sungho 21:57, 22 March 2008 (UTC)

As mentioned before it looks great but i dont know if this is required but you could add a section regarding current researchNjppatel 18:40, 13 March 2008 (UTC)

Wow you site looks great, i like how you included pictures to help solidify concepts.Njppatel 18:40, 13 March 2008 (UTC)

Great job group! This site looks fantastic! The fermentation stuff is great, and thanks for adding links for the microbes, Heather

Overall its a very good job, I did have one comment on the section processes, the sentience : ‘Through this variation of soil condition, various gases are emitted into the atmosphere or environmental factors, such as redox potential (Eh), pH, acidity, alkalinity, and salinity, are continuously changed’.. needs some editing to make it clear what your trying to say.Calgilbert 15:37, 12 March 2008 (UTC)

Thanks. I just corrected or to and..Sungho

way to go group, way to pull through at the last minute. Good job everybody especially sung ho. -david Dtla 07:50, 10 March 2008 (UTC)````

I would remove section 2.3.2. Move that material (renamed microbial activity) as part of the intro to microorganisms involved. I would rename that section something like key microbial processes and organisms involved.

Kate Scow 02:09, 10 March 2008 (UTC)

I fixed it Sungho 05:27, 10 March 2008 (UTC)

wow this is looking nice! Methaneous organisms needs to be changes to methanogens. You also need to add the fermenting organisms as a category. Also include some of the broader changes with flooding: gleying, and what happens when oxygen becomes available again. Kate Scow 02:04, 10 March 2008 (UTC)

I added gleying soil and reaerated soil. Sungho 21:50, 22 March 2008 (UTC)

are the plants linked to microbes now?-david Dtla 01:07, 10 March 2008 (UTC)

It's better, bur organize the information (one main idea per paragraph). Irina C 01:12, 10 March 2008 (UTC)

im doing effects on life, plants, microorganisms? -david ````Dtla 00:10, 10 March 2008 (UTC)

The section called "Effects on life" seems out of place. Also, if you want to talk about effects on plants, you need to link it to microbes (i.e. what do microbes to in flooded soils that would effect plants). As it is now, there is no connection to plants. Make sure you site your sources and do not just copy and paste text as you did with at least some of the phrases in your section. You have to paraphrase AND cite the source of the information. Your section on microorganisms is ok but seems try to make it more clear and make sure it doesn't contain info that is covered elsewhere on the page (compare to "electron tower" section) Irina C 00:29, 10 March 2008 (UTC) ok-david

is what im doing ok? a i supposed to make my own page? -david ````Dtla 06:00, 9 March 2008 (UTC)

It looks good. You guys need more detail in some sections. Have you decided among yourselves how to split up the work? Irina C 06:42, 9 March 2008 (UTC)

I erased your "edits and dates" section. We don't need this since we can see who did what and when in the history tab.

I would suggest slightly different organization.

Maybe under flooded soils could be....

1. Overall definition and description of phenomenon of flooded soils. You can put a figure here. You can also say that this type of phenomenon can also be observed in other types of situations.....aggregates and pollutant plumes in groundwater
2. Chemical changes : Make sure you focus this on redox. organize these by changes in dominant electron acceptors being used and make the connection to electron tower. ALso include fate of products generated during electron acceptor untilization. e.g. methane migrates up. Sulfides.....
3. Changes in microbial community composition
4. Changes when the flooded soil is unflooded and oxygen comes in

Maybe something else??
