"Soil" is material capable of supporting plant life. Soil forms through a variety of soil formation processes, and includes weathered "parent material" combined with dead and living organic matter and air. Soils are vital to all life on Earth because they support the growth of plants, which supply food and oxygen and absorb carbon dioxide and nitrogen. (From Wikipedia)
The Soil Science Society of America (SSSA) is working with the Smithsonian Institution's National Museum of Natural History in Washington, DC, to plan a soils exhibit as part of their Forces of Change Program. The exhibit will include a display of state soil monoliths and an educational, interactive section to help the museum's more than six million visitors a year understand how soil is intricately linked to the health of humanity, the environment and the planet.
