Composting in Ohio: A tour of the industry
After checking out the Barnes Composting facility (pictured) during the 2017 Composting in Ohio tour, participants learned about research using dredged materials, the dredged materials processing facility at the Port of Cleveland, and Ohio's beneficial reuse regulations. They also toured the Port of Cleveland facility which is run by Kurtz Bros. Inc.

2017 Manure Science Review
The 2017 Manure Science Review was held on August 2 in Paulding, Ohio. The 225+ participants learned about best practices for using solid and liquid manures, cover crops, and more. Demonstrations included smoking tile drains, calibrating a manure spreader, and many different applicators.
