Picking the proper planter attachments for corn planting depends on many factors, including crop rotation, soil conditions and farm practices. Start by reviewing your coulter, which cuts residue while leaving it in place in a no-till setting, allowing disc openers to get into the soil.
"When I’m just trying to cut through the residue, I wouldn’t use a wavy coulter such as this, which is designed for tillage," says Farm Journal field agronomist Ken Ferrie in Corn College TV Season 3. "I would use a fluted, slightly fluted or bubble coulter that would go down in the soil and be very sharp."

On the other hand, a wavy coulter can be used to perform tillage in tough, silt loam soils.
"I’m going to make sure this coulter stays a ¼" above the seed depth," he says. "Once we move into a tilled situation, I’m going to recommend the coulter come off because this coulter really running in tilled soil is going to push residue down, it’s going to push it in the furrow and we’re going to have trash pinning."
A variety of row-cleaner options are available to complement those functions.
