"Assessing the Effects of Lake-Dredged Sediments on Soil Health: Agricultural and Environmental Implications on Northwestern Ohio" with Angélica Vázquez-Ortega and Russell Brigham

Shipping accounts for a large portion of the Ohio economy. Channels therefore need regular dredging to keep shipping channels clear. In the past, such sediments were often released back into Lake Erie. However, as this can cause environmental problems, the Ohio legislature banned the practice of open dumping in Lake Erie in 2020, creating quite the sticky situation for dredging teams. Enter Dr. Angélica Vázquez-Ortega and Russell Brigham, two researchers working to find new uses for these sediments. In this episode, we discuss their work testing the efficacy of lake-dredged sediments as farm amendments.

Tune in to learn:

• How lake-dredged sediments are processed for further use
• Ways in which sediments can improve soil health
• The relationship of sediments with Legacy P
• Future research areas for sediment use
