A free seminar tomorrow, Oct. 7, looks at CFAES’s On-Field Ohio project. The project is using field-scale, edge-of-field monitoring to revise the Ohio Phosphorus Risk Index. Ohio farmers use the index to make management decisions about how much phosphorus they should apply to their crops. A well-tested, further-vetted index will lead to less phosphorus runoff into water, a cause of harmful algal blooms. CFAES’s Libby Dayton is the speaker. She talks about the index in the video above.
