There are more living creatures in a shovel-full of soil than human beings on the planet, yet more is known about the dark side of the moon than about soil. These are just a couple of the fascinating facts visitors can learn from the new temporary exhibition "Dig It! The Secrets of Soil," opening July 19 and continuing through Jan. 3, 2010, at the National Museum of Natural History.

The 5,000-square-foot exhibition reveals the complex world of soil and how this hidden ecosystem supports nearly every form of life on Earth. The exhibition is sponsored by the Soil Science Society of America and the Nutrients for Life Foundation, which is underwritten by The Fertilizer Institute.
