Roller Crimping

Roller crimping is a technique used to terminate cover crops ahead of no-till planting a cash crop. It is a high management system that requires an adaptive management approach. Roller crimping is most commonly adapted to terminating cereal rye cover crop ahead of no-till soybean production in US cropping systems. Visit our full guide to roller crimping here or continue reading below.

Roller crimping may be right for you if you are...

  • An experienced no-tiller
  • Growing later planted soybeans
  • Willing to plant green or into high residue
  • Comfortable with cereal rye cover crop potentially setting viable seed (for those raising small grain crops, this is a major risk to be managed or completely avoided)
  • A farmer looking to reduce tillage and/or herbicide use

The Purdue Extension Organic Agriculture Program is proud to offer a roller crimper available for lending for any operation. To learn more about our roller crimper, contact Michael O'Donnell.
