"The critical period of cover crop management: A framework for maximizing biomass potential and minimizing volunteers with buckwheat" with Dr. Andrew McKenzie-Gopsill
Buckwheat can be a powerful driver of ecosystem services in potato rotations grown in Canada, but with its long-lived seeds and ability to make a whole lot of them in a short time, it can also pose a serious volunteer problem. In this episode, Andrew joins me to discuss how creating a framework to reduce volunteers can help keep this helpful plant from turning into a fearsome weed.
Tune in to learn:
· How potato farming is done in Canada
· What ecosystem services buckwheat provides
· What qualities can turn buckwheat from a helpful crop to a difficult to control weed
· How combining tools from weed management can help keep buckwheat under control
