December Program Highlights Illinois Centennial Soil Archive Project

HEATHER WILLIS

URBANA, ILLINOIS

Illinois soils tell both a story and reveal a history of how soils have changed over the centuries. To understand more, University of Illinois Urbana-Champaign needs help from residents and landowners. During a free program, Andrew Margenot, Illinois Extension specialist and associate professor in the Department of Crop Sciences, part of the College of Agricultural, Consumer and Environmental Sciences, will visit southern Illinois to share recent findings and discuss how local residents can get involved with the Illinois 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 campus.

Margenot and team have spent four years recovering and curating the archive of soils sampled from 1899 through the 2000s. With the Illinois Nutrient Research and Education Council, Illinois Farm Bureau, and residents, researchers now wish to resample these locations to identify how soils have changed over time in Illinois.

Margenot will discuss findings and share how landowners can contribute to the project during a free program at 5:30 p.m. on Dec. 11 at the Giant City Visitor's Center at 1-245 Giant City Rd in Makanda.

In a recent ACES interview, Margenot shared project goals that will "Yield unprecedented insight into our state's soil resource base and enable improvements in soil fertility management and conservation."

"The original soils and approximately 450 locations we seek to resample are located on private land, often fields," says Margenot. "We are looking to identify and contact landowners and producers to ask permission to sample soils."
