Soil pH is often highly variable within fields, as demonstrated in this map of a single central Alberta field. The range is from red (pH of 4-4.5) to dark lime green (pH of 7.5-8). That is why grid sampling is an important step in lime application.

If you have low soil pH, should you lime?

It can take tonnes of lime per acre to move soil pH from 5 to 7, but improved fertilizer availability for all crops, better nodulation for pulse crops and alfalfa, and reduced risk from clubroot in canola can make the investment worthwhile

Reading Time: 5 minutes “Finally.” That word got special emphasis when Doug Penney was asked about liming. “It has become a hot topic… finally.” Penney, a long-serving Alberta Agriculture fertility specialist and now semi-retired crop consultant, says many fields in Western Canada — especially in Alberta — probably would have benefited from lime a long time ago. Fields most […] Read more

Six steps to help prevent clubroot in canola

Six steps to help prevent clubroot in canola

Back in 2013, John Guelly discovered some dead canola plants with ominous-looking root galls at his Westlock-area farm. But even though clubroot was already known to be in his area, he hadn’t seen it himself, and he wasn’t sure what it looked like. People were secretive about the disease, he told farmers, agronomists and other[...]

Plants that look healthy can also have small clubroot galls. While these galls may not cause much yield loss for this plant, they will produce billions of spores that can be spread around and cause yield loss the next time canola goes on that field.

Dealing with a flush of clubs

Clubroot specialists across the Prairies are sharing how to slow the disease’s spread, and how to keep it down when it does arrive

Reading Time: 4 minutes It turns out 200 kilometres of forest is not an impenetrable barrier for clubroot. Canola growers in the Peace River region had crossed their fingers, but knew deep down it couldn’t hold. “Most growers knew we weren’t living in a bubble up here,” says Gregory Sekulic, Canola Council of Canada agronomy specialist for the region.[...]

Six management steps to help prevent clubroot

Reading Time: 2 minutes The first step in managing clubroot is to minimize the chance of introducing clubroot to the farm in the first place. Make sure equipment and vehicles entering fields are clean. All people entering a field should have disinfected rubber boots or wear disposable booties over their footwear. All seed (not just canola) should be cleaned[...]

Clubroot climbs up into Peace region

Reading Time: 2 minutes One of Canada’s northernmost farming areas has picked up a case of a disease well known to canola growers further south. Alberta Canola on Wednesday announced the Peace region has reported a case of clubroot in canola, in Big Lakes County, which surrounds much of Lesser Slave Lake in the region’s southeast. The disease has[...]

VIDEO: Curbing clubroot in Ontario canola

Reading Time: < 1 minute During a recent canola growers’ day at Arthur, Ont., Dan Orchard, an agronomist with the Canola Council of Canada, brought his years of experience managing clubroot in Alberta to Ontario growers. Canola fields affected by clubroot were first found last year in Ontario. With some diligence, Orchard said, the problem should be able to be[...]

Syngenta exits canola seed business

Reading Time: 2 minutes Canola growers checking out Syngenta Canada’s 2018 seed guide for Western Canada will notice canola by its absence. Syngenta, which entered the Prairie canola seed market in 2013 and by this spring had six hybrid varieties on offer, said in a statement it has “recently taken the decision to exit the canola seed business.” The[...]
