Yvonne Lawley - Strip Till - Yetter - research

At the University of Manitoba Ian N. Morrison research farm, near Carman, Manitoba, the Farming Systems Lab lead by Dr. Yvonne Lawley uses an 4-row plot scale strip till unit to create strips or zones of tillage in this field with heavy amounts of chopped corn residue. This experiment sized Yetter strip till unit is equipped to test different fertilizer treatments when using strip till. In slow motion, you can see the leading cutting coulter that cuts large pieces of residue, followed by round residue cleaners that move residue out of the strip. Then follows two discs that do the actual soil tillage in the strip followed by a rolling baskets that smooths the seed bed and creates a rounded berm that will help to warm the soil in the strip. In this video we were strip tilling in the fall after harvest to create strips for seeding a crop the next spring.
