The world was in massive celebration on December 5. If you were wondering what all of that was about, it was because it was World Soil Day. Soils are great and we tend to under appreciate what they do to sustain life on planet earth. Members of our research group at the Sydney Institute of Agriculture within The University of Sydney put together a SOILinar to tell the world that soils do matter. Our SOILinar highlights some of the research we do, and is presented as a number of shortish clips by various members of our research group. Be prepared to learn something new and enjoy.
