Three Experiences with Roller-Crimping Cover Crops

By Practical Farmers of Iowa


Roller-crimping as a method for terminating cover crops in organic and no-till farms in Iowa is gaining interest, but many questions still remain about best management practices. In this farminar, three Iowa farmers will share their experiences using a roller crimper in their respective organic operations.  Scott Shriver and Francis Thicke will focus on cereal rye going into soybeans, and Billy Sammons will share his experience with hairy vetch going into corn.

  • Billy Sammons farms with Joanna Hunter near Churdan. They are in the process of transitioning to organic certification and are incorporating many no-till principals. Billy has used a roller-crimper for two seasons.
  • Scott Shriver has been growing corn, soybeans, and small grains organically near Jefferson for 18 years. Scott has grown rye cover crops for years but just started experimenting with a roller crimper in 2017.
  • Francis Thicke is a soil scientist and organic, grass-based dairy farmer near Fairfield, who has experience rolling a cereal rye cover crop after drilling soybeans.
