Illinois Centennial Soil Archive Project

NREC is supporting a project led by Dr. Andrew Margenot of UI that is focused on sampling soil locations throughout Illinois that had previously been sampled dating back to 1899. The goal of the project is to compare modern soil samples with the original samples to gain insight on how Illinois soils have changed over the last 120 years. This will ultimately enable improvements in soil fertility management and conservation as well as updating the Illinois Agronomy Handbook.
The 450 locations to be sampled are largely located on private land. Click the attachments for more details on the project. Scan the QR code on either document to see the 450 locations marked within google maps. If you have any questions or can help in any way with gaining permission to these sites to be sampled, please contact or
