Jon Schoonover, Professor


Dr. Schoonover serves as Professor of Physical Hydrology and Soils in the Forestry Program at SIUC.

His research focuses on the impacts of land use on a water quality, hydrology, soils, and channel morphometry.  His most recent work has involved testing and designing Best Management Practices for use in row crop agriculture.  Dr. Schoonover teaches courses in Tree Identification, Watershed Management, Soils, and Aquatic Resource Management.

Research Interests and Specialties

Impacts of land use on water chemistry, hydrology, channel morphometry, and sediment transport; fecal coliform contamination across multiple land uses; water resource stress associated with urban-rural interfaces; biogeochemistry of floodplain forests; and riparian zone management in agricultural systems.

Steven Bachleda - M.S. candidate
B.S. Hydrology, University of Wisconsin, Stevens Point

SIU Grad Steven Bachleda

Steven is looking into the integral relationship between nutrient runoff, erosion control, and crop yields with the use of cover crops in no-till agricultural fields in southern Illinois. This will be done by researching two agricultural watersheds having different treatments (one with cover crops and one without). He is testing how different cover crops affect the chemistry of the soil water and the surface runoff.  The soil of the two watersheds will also be examined to research how cover crops impact crop yield productivity. 


SIU Grad Kevin TurnbowKevin Turnbow - M.S. Candidate

Kevin’s research focuses on the on effects of agricultural best management practices (BMPs). His research is currently investigating the relationships between two BMPs; Cover Crops (CC) and Water and Sediment Control Basins (WaSCoB). The research utilizes four treatment conditions; 1. No WaSCoB and no CC, 2. No WaSCoB and CC, 3. WaSCoB and no CC, 4. WaSCoB and CC. His project is a 4-year study that aims to identify changes in water quality, soil health, and crop yields in response to implementation of these practices. 



SIU Grad Emma EldridgeEmma Eldridge – M.S. candidate B.S., McKendree University

Emma’s research focuses on the use of saturated buffers on tile-drained fields, taking place in Sullivan, Illinois. In this project there is a standard buffer design, and an experimental design in which the tile lines are arranged in a pitchfork shape. The objectives of this study are to monitor the impacts on water quality (nitrogen and phosphorus) and quantity reaching the tile outlet. Monitoring will continue through 2023. Her data will provide a side-by-side comparison of the new buffer design and the standard saturated buffer. Emma’s research will lead to insight on the efficacy of saturated buffers in Illinois, as well as the potential criteria for new saturated buffer designs.
