Call in a nurse. A “nurse” crop that is

A second crop planted along with potatoes protects the soil and boosts yields

By
Reading Time: 3 minutes Recent years have seen increased attention on the health of the soil used in potato production, and attempts to bring potatoes into longer rotations with other crops. In the Maritimes, seed companies are promoting soybeans or corn as rotational options and McCain has developed one- and two-year multi-species cover crop blends to help boost organic […] Read more
Dallas Timmerman uses a Leon scraper to put topsoil back on his eroded and degraded hilltops. He also adds manure. These measures don’t take a lot of time and have led to a large yield increase on those acres.

Timmerman trains the Tiger Hills of Treherne

A Manitoba farmer has seen major yield improvement by recapping his hills with topsoil from his lower land

By
Reading Time: 5 minutes Dallas Timmerman farms in the Tiger Hills around Treherne, Man., and sometimes those tigers need training. “We have a lot of hills and sometimes you need to be aggressive with them,” he says. Timmerman’s chair and whip are a Leon scraper and Versatile 4WD. He started training his hills over a decade ago, working on […] Read more

The next green revolution

In this Ontario lab, bacteria are working to drive nutrient uptake and accelerate crop growth

By
Reading Time: 4 minutes Scientists are delving deeper into the soil in hope of finding that next innovation to boost yields while enhancing soil health and reducing pollution concerns. And it seems they’re onto something. Or, better yet, some things. In particular, a scientist with Agriculture and Agri-Food Canada (AAFC) has looked inside decomposing corn roots in southern Ontario […] Read more
A researcher and soon-to-be author wanted to know what’s getting in the way of healthier soil. What she heard from farmers, industry and academia is it’s not a lack of technology but a lack of political will and financial support.

Where Ontario’s soil health strategy falls short

Farmers understand the crucial role of soil health for feeding the world. So why is it such a struggle to get support for that goal?

By
Reading Time: 6 minutes Last fall, Dr. Sarah Rotz, then working at the University of Guelph, wrote an article with Guelph crop scientist Dr. Ralph Martin and York University agri-food policy researcher Dr. Rod MacRae to draw attention to what they perceive as shortcomings in the Ontario government’s Soil Health Strategy. It’s a topic Rotz had been studying for […] Read more

Real work on soil health needs to be done

Fine speeches about our soil make us all feel good, but there's an increasing urgency for wider adoption

By
Reading Time: 5 minutes Soil health has received considerable attention in recent decades. There have been many champions who have promoted the benefits of good soil, farm organizations that have mounted campaigns to encourage its development and even Senate committees trying to help government recognize the urgency surrounding it. Yet reluctance to raise the bar on the subject remains. […] Read more

What’s good about soil?

Soil health indicators often relate to properties that you can’t see

By
Reading Time: 6 minutes We’re planting more cover crops, we’ve got a heightened focus on soil organic matter levels, and now we’re adopting what’s thought to be a relatively new term: soil health indicators. They’re each part of a wave that’s been building, reflecting a renewed interest in the soil as the basis for all crop production. “It’s been […] Read more

A change in equipment vs. a change in mindset

Refocusing attention on soil health is the driver behind newer technologies

By
Reading Time: 4 minutes A number of years ago, Carl Brubacher looked at his soils and realized something had to change. He’d been relying on a full complement of tillage passes and he could sense his topsoil levels were becoming shallower. What he wanted was to find a way to avoid falling into the trap the U.S. has experienced, […] Read more

Get there on time

Timely delivery is a big plus for “fertigation,” but can you afford the costs and the management demands?

By
Reading Time: 7 minutes In precision agriculture, the focus is typically on the low-hanging fruit, i.e. the use of yield data to create variable-rate fertilizer scripts, investing in individual row units with automatic down-force, or using aerial imagery to pinpoint trouble spots in a field. Most such discussions are also confined to choices about soil, seed and fertility. Yet […] Read more

Four ways to increase your organic matter

A question that I hear a lot is, “How do cover crops fit into a grain operation?” Lots of grain farmers have no desire to get into the livestock business and no interest in producing hay. But many have some soil issues that need to be addressed. This can be done by buying more iron[...]

The crop rotation effect

At last, scientists hope to explain exactly why rotations are such a good practice

By
Reading Time: 7 minutes It’s one thing to know the benefits of a practice, it’s another to understand the “why,” especially when it comes to biological functions where the road to understanding can be anything but simple. In cropping terms, science has known about the benefits of longer rotations for years, but not about the exact reasons why. This[...]
