Tip: Categorizing images edit
Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.
Here's how:
1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:
2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.
[[Category:Category name]]
For example, if you are uploading a diagram showing the orbits of comets, you add the following code:
[[Category:Astronomical diagrams]]
[[Category:Comets]]
This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".
When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").
Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.CategorizationBot (talk) 10:56, 27 April 2010 (UTC)

Structural Soil edit
Structural Soil is a medium that can be compacted to pavement design and installation requirements while permitting root growth. It is a mixture of gap-graded gravels (made of crushed stone), clay loam, and a hydrogel stabilizing agent to keep the mixture from separating. It provides an integrated, root penetrable, high strength pavement system that shifts design away from individual tree pits.[1] Rhynko (talk) 14:25, 27 April 2010 (UTC)
Problems with Typical Installations edit
Previously the main problem facing the establishment of trees in paved areas is the lack of enough volume of soil for tree root growth. Soils under pavements are typically so compacted that it stops roots from growing. Older established trees with their roots under pavement grow poorly and often die. They can also cause pavement failure and displacement. Overall pavement preparation and repairs can shorten the life expectancy of a tree to 7-10 years where we could see them grow for at least 50 more years.[1] Rhynko (talk) 14:25, 27 April 2010 (UTC)
CU-Structural Soil™ edit
Structural soil was researched and developed in the 90’s by Cornell University’s Urban Horticulture Institute. In 1999, AMEREQ signed a licensing agreement with Cornell University and currently holds the patent rights to Cornell’s CU-Structural Soil™ Urban Tree Planting Mix. It is marketed as CU-Structural Soil™ for quality control and is produced by a network of qualified AMEREQ-licensed companies. CU-Structural Soil™ on average costs $35-$42 per ton. Other companies have formed their own brand of structural soil based on Cornell’s work. For example, STALITE has developed STALITE MATRIX ™ Structural Soil that they claim holds more moisture.[2][3][4] Rhynko (talk) 14:25, 27 April 2010 (UTC)
Composition edit
As discussed above, structural soil is composed of crushed stone (typically limestone or granite) narrowly graded from ¾-1 ½” highly angular with no fines, clay loam which should conform to the USDA soil classification system. The hydrogel is added in a small amount to prevent the separation of the stone and soil during mixing and installation. Usually a layer of stone is spread, then the dry hydrogel is spread evenly on top and screened moist loam is placed on top. The entire mixture is then turned until a uniform blend is produced. Structural soil is not typically stockpiled; it should be mixed and installed soon after delivery. If a stockpile is required, the soil needs to be protected from the elements so it does not become contaminated. Installation typically calls for two cubic feet of soil is needed for every square foot of crown projected. It is also recommended for irrigated trees to have a low-volume drip irrigation. Cornell also suggests a minimum of 24” to 36” for CU-Structural Soil™ depth and they have established no minimum for length and width of installation, however, because it is a structural soil it was designed to go under the entire pavement area. Testing has shown that structural soil is safe around utilities and that you can use trees from any production system such as balled-and-bur lapped, bare root, containerized and boxed trees.[1][4][5] Rhynko (talk) 14:25, 27 April 2010 (UTC)
Continued Development edit
Cornell is continuing its development of CU-Structural Soil, expanding its use as the need for trees and other greenery within highly urbanized areas grows. CU-Structural Soil as been used in over 1000 applications and has been proven a very viable option for construction in cities.[4] Rhynko (talk) 14:25, 27 April 2010 (UTC)
