Antimicrobial use under the microscope Expert says ‘there definitely is a chain’ connecting farms to the rise in antimicrobial resistance By Alexis Kienlen af staff
Cover crops come with a long list of benefits Restoring tired soils isn’t a quick process, but cover crop proponents say it’s well worth the effort

ntimicrobial resistance is like a forest fire — because only you can take steps to prevent it. Think about resistance every time you use antimicrobials, producers were told during Alberta Pork’s latest telephone town hall. “Any single time one of us uses an antimicrobial, we are tipping the scales toward resistance, said Dr. Leigh Rosengren, a veterinarian and consultant with Rosengren Epidemiological Consulting. “Does that mean that we should never use them? Absolutely not. What we need to do is stop and think of the cost — both the tangible economic cost of the drug and the larger societal cost of resistance to the immediate benefit of your herd in the use.” By 2050, 10 million people around the world could die each year from antimicrobial-resistant infections. And 18,000 people in Canada are hospitalized each year with an antimicrobial-resistant infection. “When we use a product in our pigs, we kill off the susceptible bacteria and resistant bacteria are the population that’s left,” Rosengren said on the conference call. “They go on to

re you looking to improve soil nitrogen? Prevent soil erosion? Reduce soil compaction, improve water infiltration, and even suppress weeds? Cover crops have got you covered. And as understanding of their benefits spreads, interest is growing. “I think producers are realizing the cost of inputs is getting very, very high and the soil has become just a medium to hold the roots,” said Nora Paulovich, manager of the North Peace Applied Research Association. “They have to feed it with high-cost inputs to get any production. They’re realizing their soils are being degraded.” Cover crops are a major shift away from the “quick-fix” approach that producers are used to, she said.
“If you had a weed problem, you just went out there and sprayed it; if you had a fertility problem, you just went out and applied more commercial fertilizer,” said Paulovich. “Patience is the biggest factor in all of this. We’re not going to see overnight results. Trying to improve soil health using these different methods is going to take time.” Cover crops focus on five steps to improving soil health, which Paulovich summarizes as “keep a cover, practise zero till, increase plant diversity, keep living roots as long as possible, and integrate livestock if you can.” Producer interest is growing, slowly but surely. In 2013, a group of producers from Manning began discussing how they could get more production out of their soil and opted to try cover crop cocktails. “The interest was overwhelming,” said Paulovich. “This really is coming from the
producers. It’s not coming from above — Alberta Agriculture or the applied research associations aren’t saying, ‘Hey, soil health’s really important.’ “The producers are coming to us and saying, ‘This is really important, and we want to learn more.’”
Tired soil
That’s what led Kevin Elmy to explore cover crops on his farm near Saltcoats, Sask., six years ago. “The healthier soils we have, the easier it is to farm with less stress,” said Elmy, a certified seed grower. “Canola is extremely hard on the soil, and when you start growing lots of canola, one of the things that suffers is your mycorrhizae in the soil. By producing cover crops, we’re able to stimulate and really build our mycorrhizae levels, which are really helping with soil health.”
