The Door-Kewaunee Demonstration Farm Network is planning a field day Thursday for area farmers to learn details of Kinnard Farms’ tile line bark bed filter demonstration project.

The event is scheduled for 1-3 p.m. at the site, Duvall Road and County Line Road just north of Duvall.

The new filter strip is intended to help the farm grab any dissolved nitrogen that may escape the root zone.

Participants will hear from the NRCS design team of Jae Sutherland, Joe Johnson and Barry Bubolz as well as Larry Jarosinski of Angelica Tile Co.

Farm owner Lee Kinnard will talk about the focus and logic behind the project.
