Editorial: Gritty winds of change

By
One of the downsides of spring, aside from its slowness to arrive, is the wind. Invariably before crops get established, we get a series of major wind events that cause soil to move, shearing off the newly emerging plants, and filling ditches with dirt, the air with fine particles and our teeth with grit. These
... the health of one soil can be very different from the health of another and both are healthy.” – David Lobb, University of Manitoba.

Soil health a moving target

There’s no one-size-fits-all measure of soil health, David Lobb says

By
Saying a soil is ‘healthy’ isn’t something simple like running through a checklist. David Lobb, a soil scientist at the University of Manitoba says it’s a moving target that takes many variables into account. There are hundreds of different soils across the province, thousands across the country and the development of each one moves toward
The long shadow of the 1930s dust bowl may have resulted in an inaccurate assessment of wind erosion risk.

Soil erosion concerns overblown?

Academic says soil loss to wind erosion isn’t backed up by data

By
David Lobb has spent much of the last year challenging long-established beliefs about wind erosion. The University of Manitoba soil science professor and his team recently completed a study of the historical and contemporary evidence of wind erosion on the Prairies and the findings run counter to deeply rooted assumptions about wind erosion that have

What’s blowing in the wind? Maybe not your soil

A recent study on land rolling shows that wind erosion doesn’t cause severe soil loss

By
A recent Manitoba study shows wind erosion may not be the soil stealer it’s cracked up to be. “It’s a perception issue,” said David Lobb, a soil scientist from the University of Manitoba. While recent images of dirty snow — or “snirt” — and the towering clouds of topsoil from the dust bowl era are

Soil degradation a costly global issue

About a third of the world’s soil is degraded, which has economic and food security implications

By
When Prairie-dwellers think of soil erosion, they may think of iconic photos from the Dirty ’30s: towering clouds of black soil blowing across desolate land, teacups turned upside down against drifting grit. But as Francis Zvomuya told the classroom of farmers and agronomists at the Global Forum on Soil Stewardship, soil degradation is far from

The vertical-tillage question defies pat answers

The controversial practice can serve a purpose, but won’t solve soil compaction

By
Vertical tillage is a tricky term to grapple with. It’s less a method of tillage than it is a grouping of implements sold under that banner. It is marketed as a means to deal with soil compaction but in reality the implements marketed under that umbrella do little to address that problem. Yet, in certain

Our History: April 1949

Our April 21, 1949 issue carried this “10 little dust devils” cartoon from the USDA Soil Conservation Service. The 10 arrive at a windbreak and drop one by one as they meet a windbreak, a listed field, a clover field, a grass waterway, a fish pond, a field of stubble mulch, a cover crop, a

Editorial: Who needs convincing?

Maybe it’s just a guilty pleasure or maybe you can justify it by saying it’s good mental exercise, but one way or another I confess — I watch “Jeopardy.” One of the benefits of being semi-retired is that you can be home to watch it at 4:30.
