In Episode 7 of Corn College TV Season 2, Farm Journal Associate Field Agronomist Missy Bauer gives an example of tillage for corn-on-corn.
“A disk ripper will incorporate residue and rip up root balls,” she says.
An example shows a tool set at 15” center and the proper about of shatter between the shanks.
“We want loose soil through the profile and run deep enough to get shatter,” she says.
