Wikipedia:WikiProject Soil

WikiProject Soil is a project to organize and improve articles related to soil.

Articles maintained by this WikiProject are grouped in Category:WikiProject Soil by using the {{WikiProject Soil}} template.

Soil is defined as:

  • The "material that forms at the interface of the atmosphere and the lithosphere which is capable of supporting plant growth" (White 1997).[1]
  • A critically important component of the earth's biosphere maintaining local, regional, and world-wide environmental quality (Doran & Parkin, 1994).[2]
  • The "different forms of earth on the surface of the rocks, formed by the breaking down or weathering of rocks."[3]
  • A "natural body composed of solids (minerals and organic matter), liquid, and gases that occurs on the land surface, occupies space, and is characterized by one or both of the following: horizons, or layers, that are distinguishable from the initial material as a result of additions, losses, transfers, and transformations of energy and matter or the ability to support rooted plants in a natural environment."[4]
  • The granular material on the surface of other celestial bodies. Lunar soil and Martian soil are terms in general use that fit within the context of this project.



  1. Verify content. Use reliable sources per WP:SCIRS. Read this Signpost editorial.
  2. Improve soils-related content at Wikipedia. See Suggested WikiProject Soil Tasks.
  3. Assess soil-related articles for quality and importance. See Assessment Department and Change Log. Use {{WikiProject Soil}}.
  4. Monitor for vandalism and substandard edits. You can narrow your efforts to monitoring your most active category.
  5. Upload public domain soils images from USDA and USGS to Commons:Category:Soils. image source listupload link
  6. Collaborate on soil article tasks identified at WikiProject Ecology, WikiProject Geology and WikiProject Ecoregions.

Other participants


  • May 2016 - started Template:Soil science topics (could also be: Soil topics)
  • January 2016 - Inactive tag removed.
  • March 2014 - This project is tagged for inactivity.
  • May 2010 - template:Infobox soil has been created by Chiton magnificus. Feel free to modify it and to add it to soil articles.
  • April 2009 - Earth Sciences book created.
  • April 2009 - Added Category:Soil_articles_needing_attention.
  • September 2008 - {{soil type}} infobox created. Supports Task 5, above.
  • September 2008 - Nine project articles are selected for inclusion in WP Version 0.7 DVD. Given the opportunity of a two month reprieve, now is the time for project participants to review and improve these articles.
  • July 2008 - The C-Class was added to the assessment scale, prompting a flurry of article improvement and reassessment, but also lengthening bot article assessment cycle from days to weeks.
  • May 2008 - Another public domain soil profile photograph, Image:Narragansett_silt_loam_URI.png, is deleted as unsourced.
  • April 2008 - Two public domain soil profile photographs, uploaded by briefly active User:Jimjet, deleted as unsourced. Jimjet did not specify that he took the photographs as an employee of USDA, and he did not respond to dispute their removal. Deleted photos were of George Demas (Image:GeorgeDemas.png), and a Paxton (soil) profile (Image:Paxton Soil.jpg).
  • December 15 2007 - The article "Alfred Hartemink", apparently created by International Union of Soil Sciences Deputy Secretary General Hartemink about himself, survives AfD.
  • December 1 2007 - Category:Soil created.
  • September 17 2007 - Soil de-listed from good article status due to lack of breadth and a bias towards soil science.
  • February 10 2007 - Soil achieves good article status.
  • December 20 2006 - In an IUSS alert, emailed to 12,000 people, the International Union of Soil Sciences encourages members to contribute to Wikipedia, and alerts readers to be aware of this project.
