Error in Soil Chart

The soil chart currently linked in the article appears to have an error in it; the bottom label should be %sand, not %soil (since it's all soil). Endovior (talk) 04:54, 25 July 2023 (UTC)[reply]

I noticed that too, I found this but it's without the comments and the example: https://www.researchgate.net/figure/USDA-Soil-Texture-Triangle_fig2_279631053 DylanLow108 (talk) 15:48, 29 May 2024 (UTC)[reply]

Triangle plot

One of the axis of the soil texture triangle plot says '%soil'. This should be '%sand', because 100% of it makes the soil sand, and the text of the image says the third soil type is sand, and every image I found on the internet, labels the axis as sand. I don't know how to edit this. Wikifan153 (talk) 09:37, 25 September 2023 (UTC)[reply]

I didn't notice this before I published my other comment (sorry), I've added a link to Soil texture, the graphs there appear to be more correct. Unfortunately I'm not sure how to change the image 'professionally' yet... DylanLow108 (talk) 15:58, 29 May 2024 (UTC)[reply]

I've switched image files to use the correctly labelled version at Soil texture. Other versions are available such as File:SoilTexture USDA.svg, which uses colour to emphasise the different fields and I find easier to read. Mikenorton (talk) 16:28, 29 May 2024 (UTC)[reply]

Inclusion of Elaine Ingham

I want to suggest we find a location in the article to include/reference Elaine Ingham and perhaps secondarily on pages such as soil food web. In addition to her important research on soil microbiology (which is not well described on her page) she is a ceaseless educator and advocate for soil restoration who has done probably as much outreach and training as anyone in the field. (Maybe also a good candidate for attention by Wikipedia:WikiProject Women scientists. ) Beyond what is noted on her page, she was (one of) the first to advance the premise that soil contained tens of thousands of bacterial species/gm, long before there was confirmation of this level of biodiversity by rRNA/DNA testing.

Active sites

What type of active sites do we have in solid phase and adsorbate are being adsorbed on each active site? Strength Masamba (talk) 17:39, 9 April 2024 (UTC)[reply]
