Erosion often steals yield from hilltops and knolls in the field: Here are some ways to get it back
Get your topsoil moving
Landscape restoration can offer immediate yield boosts
If you farm in the Prairie pothole region, you’re dealing with some yield loss due to tillage erosion, says Marla Riekman, land management specialist for Manitoba Agriculture. The good news is there’s a relatively easy way to restore that lost yield potential: simply move the eroded topsoil back up the slope. Riekman was at this
Degraded soils cost farmers billions annually
Yet soil care remains a low priority for policy-makers as well as farmers
Farmers have reduced the amount of soil they lose through annual cropping practices, but they continue to carry a costly legacy of degraded soils, a University of Manitoba soil scientist says. David Lobb used crop production data and computer models to estimate how much lost productivity has occurred over the past four decades due to
Rolling wet soil leads to compaction
Rolling dry soil can increase the likelihood of topsoil loss
When to roll and when not to roll soybeans, that is the question. Speaking at the Manitoba Pulse and Soybean Growers recent SMART day in Carman, provincial soil management specialist Marla Rickman said it’s important to wait for the right conditions to avoid topsoil loss. “Generally you want to be rolling right after seeding, but
New research raises red flag over buffer strips
A University of Manitoba researcher says riparian buffer strips may not be the answer to preventing nutrient run-off
New research from the University of Manitoba raises questions over the effectiveness of buffer strips often used around cropland to filter out nutrients before they reach waterways in run-off. David Lobb, senior research chair for the Watershed Systems Research Program and a University of Manitoba soil science professor, says riparian buffer strips are “highly inefficient”
High-disturbance seeding can be as erosive as a plow
Conservation tillage isn’t conserving as much soil as you thought. That’s why University of Manitoba soil scientist David Lobb says new tillage equipment is needed
The era of black summerfallow is over, and direct seeding and zero tillage have pretty much solved problems of soil erosion on the Prairies. Or so goes conventional wisdom. Not so, says David Lobb, a professor in the University of Manitoba’s department of soil science and senior research chair for the Watershed Systems Research Program
VIDEO: Tillage erosion and how you can avoid it
Soil science professor says it can be the most damaging type of soil erosion
You’ve heard of wind and water erosion, but how about tillage erosion? It’s often the worse of the three, says University of Manitoba soil science professor David Lobb, who spoke to Manitoba Co-operator reporter Allan Dawson Feb. 4 at the Manitoba Soil Science Society’s 59th annual meeting in Winnipeg.
Phosphorus recovery can complement source reduction
Globally, it's estimated that one-third of all phosphorous applied is lost to water due to erosion, leaching and run-off
A Manitoba engineer says phosphorus (P) recovery methods can be an important addition to the province’s phosphorus management strategies. Francesco Zurzolo, an engineer specializing in nutrient management and reduction with Dillon Consulting, says Manitoba is dealing with eutrophication and destruction of important ecosystems due to P buildup. Zurzolo spoke at the Manitoba Environmental Industries Association’s
Editorial: What’s it going to take to stop soil erosion?
Soil erosion still alive and (not) well in Manitoba
You could have mistaken Co-operator reporter Lorraine Stevenson for a coal miner, coated as she was with black dirt, after she ventured out across southern Manitoba during those 70- to 90-kilometre-per-hour winds April 15. But for the modern farm equipment and steel granaries in the background, her photographs of airborne and drifting soil could have
VIDEO: Soil Conservation Week — the job is not over
April 19-25 is National Soil Conservation Week, an annual event to remind everyone of the need to protect the soil resource from some of the damage it suffered during the “Dirty Thirties.” Unfortunately, some scenes of that time were repeated in parts of Manitoba last week when south winds gusting as high as 88 km/h
