PFI CONFERENCE RECAP: Rolling Cover Crops with Modified Equipment

By Stefan Gailans

At the Practical Farmers of Iowa annual conference last month, we held a session on terminating cover crops with rolling equipment. This session featured three farmers (Doug Alert, Dave Schmidt & Francis Thicke) sharing their experiences with rolling a cover crop from the 2015 growing season. Rolling a cover crop is not a common technique for terminating cover crops in Iowa. Elsewhere, however, this technique is used in organic systems looking to minimize tillage and soil disturbance and in no-till field crops systems looking to reduce chemical inputs.

Francis Thicke presents at the 2016 annual conference about rolling a cereal rye cover crop ahead of a soybean crop.

Below, you can find the photos/slides shared by these three farmers as well as other materials previously shared on this subject.

  • Doug Alert. Doug farms with his wife, Margaret Smith, and sons, Robert and William, near Hampton in north-central Iowa raising organic corn, soybeans & small grains, cattle, sheep and pigs. In 2015, Doug rolled a hairy vetch cover crop (seeded after cereal rye grain harvest in July 2014) in early June before planting corn. He and Margaret wanted to compare this method to what they normally do: till red clover (frost-seeded with a small grain in the previous spring) ahead of planting corn.

 

 

  • Francis Thicke. Francis and Susan Thicke run Radiance Dairy near Fairfield in southeast Iowa. In 2015, Francis rolled a cereal rye cover crop after drilling soybeans. The drill partially knocked down the rye (which was flowering) and the culti-mulcher Francis used to roll finished the job and laid all the rye flat.
