Freshwater Science: Turning Dredged Sediments into Farm Soil Nutrient Supplements

February 27, 2023 – New research from Ohio Sea Grant, Stone Lab and the Harmful Algal Bloom Research Initiative

Dredging is essential to keeping Lake Erie harbors open and working, but disposal of the dredged sediment can be problematic. Between the nutrients and other pollutants the sediment can carry, and the murky water disposal can cause, open-lake disposal of dredged sediments is prohibited in Ohio as part of an effort to prevent harmful algal blooms.

Dr. Angelica Vazquez Ortega at Bowling Green State University is examining whether integrating dredged sediments from Ohio harbors into farm soil could improve corn crop yields and overall soil health while also keeping those sediments out of land-based containment areas.

The webinar is free, but registration is required to receive log-in information.
