Post emerge spray day in our herbicide banding x cover crop experiment. We are banding herbicide over the rows and seeding cover crops in between. We have found that we can band spray soybean, grow a cover crop, and yield better than the provincial average all while reducing herbicide use by 73%!

The critical period of cover crop management: A framework for maximizing biomass potential and minimizing volunteers with buckwheat
High-biomass cover crops such as buckwheat can become volunteer issues in subsequent crops.
Accurate models to assist producers with termination timing are needed to sustain cover crop acreage.

Ecological processes affecting weed communities in Nova Scotian wild blueberry fields
Ecological gradients and processes are known to play a key role in determining weed community composition in agroecosystems. The present study investi…

Testing out our new sweep plough for cover crop termination. Seems there is a fine line between skimming the surface and burying it in the soil. This time it worked

It's spud time! First two of eight trials hand planted today. Here we are testing methods of terminating legumes without glyphosate prior to potatoes and evaluating carryover effects and leaching potential

Smiting plants with the power of Zeus! First day out testing our new Weed Zapper yesterday. A few hiccups along the way but excited to see how things look today

King of the Hill is the great American novel.
"King of the Hill" is not an animated sitcom. It is an animated, well-researched documentary on life in Texas presented as a sitcom.

Who should you nominate as reviewers for your manuscript? After a long chat with a post-grad it appears that there's a lot of misguided advice out there. Thread 👇

Buckwheat is a fast growing cover crop that is often added to mixtures to provide weed suppression. In our recent OA manuscript we show that weed suppression is tied to buckwheat's rapid canopy establishment and which is compromised in cover crop mixtures. #plantscience #sustainable #agriculture
Reduced canopy cover and development compromises weed suppression by buckwheat in cover crop mixtures
Buckwheat (Fagopyrum esculentum Moench) is a common cover crop typically grown for its rapid establishment and superior weed suppression. One challenge of incorporating buckwheat into crop rotations, ...

Seeding cover crops after potato harvest has been gaining traction over the past few years in Atlantic Canada. Yesterday I was out checking on our test plots evaluating different species sown post-harvest to see which provides the best soil cover overwinter. #sustainable #agriculture #plantscience
