When is the Best Stage to Roll Soybeans After They Have Emerged?

Submitted by Dennis Lange, MAFRD Farm Production Advisor (Altona).  Updated from Manitoba Cooperator article by Allan Dawson, published on June 27, 2013 “Trifoliate stage best for rolling soybeans after emergence”

Don’t roll soybeans until they reach the first trifoliate stage, or you risk breaking too many young plants.

  • You don’t want any beans at the hook stage
  • Only roll if you have some stones or dirt that will cause you some harvest issues
  • Wait until later in the day when it’s warmer and plants are more plastic and should have less breakage (check to see if plants are breaking) 

Why Roll Your Soybean Field?

Rolling pushes down stones and levels the field allowing the combine cutter bar to be set lower and pick-up low-handing pods.  It can make soybean harvesting faster, more efficient and will reduce the risk of stones damaging the combine.
