Ever wonder how our soil has changed over the last 100 years? Discover the incredible story behind the University of Illinois Soil Lab's Centennial Soil Archive Project. A key piece of Illinois' agricultural heritage is a world-class, one-of-a-kind soil sample archive collected when local soils were first surveyed. As early as 1899, soil types across the state were mapped by sampling fields to three-foot depth and characterizing the distinct soil layers. Predecessors had the foresight to keep records of sampling locations and to store these soil samples on the University of Illinois’ Urbana-Champaign campus.
Learn how this historical treasure helps us understand everything from the impact of farming practices to the effects of climate change. Participants will also learn about the resampling efforts going on across the state and how you can get involved.
