It takes a thousand years to form a single inch of soil. It is a fragile layer on the surface of the land - yet essential to all life on Earth. But where did soil come from and how was it made? This DVD reveals the secrets locked within the soil. Travel with the host in a mobile soil lab as he delves down into dirt to uncover its deepest secrets. Look into the distant past to reveal the almost miraculous way soil first formed and take a tantalizing glimpse into the future to reveal soil as a commodity more precious than oil or gold.
