An ongoing northeastern Saskatchewan trial looks at micronutrient applications, specifically boron, copper and zinc, to see whether those applications boost yield in canola crops.

Micronutrient applications compared in canola
Saskatchewan study aims to shed light on claims and concepts surrounding lesser-known crop nutrients
Bioreactors in tiled fields could themselves benefit from draining
Bioreactors are meant to filter nitrogen from tile water to help with runoff nutrient loads, but drying them out from time to time might increase their effectiveness
Bioreactors are meant to filter nitrogen from tile water and reduce extra nutrient running off int0 local rivers and lakes, but drying them out from time to time might increase their effectiveness.
Taking the mystery out of soil and tissue tests
Agronomists and soil scientists describe the differences between various tests
Soil tests assess the potential availability of nutrients under optimal conditions. In contrast, tissue tests indicate actual uptake under variable field conditions.
Soil health benchmarking survey in Alberta
Researchers at the Chinook Applied Research Association’s Soil Health Lab have adapted a soil health assessment from Cornell University to evaluate Alberta soils
Every farmer wants “healthy soil.” But what does that mean, and how do they know if they have it? “The first question I ask when I’m speaking to farmers is, ‘How many of you have done soil testing?’” says Yamily Zavala, PhD, soil health lab manager and soil health and crop management specialist at the […] Read more
Adding wood ash to soil both practical and cost-effective
Practical Research: Too often headed for the landfill, ash can reduce soils’ acidity and enhance cropland fertility
Here’s a perfectly good organic source of lime, with plant macro- and micronutrients, being taken from the woodlands and virtually thrown away. Wood ash is an excellent source of magnesium, calcium, potassium, phosphate and micronutrients, which can very effectively raise up acid soil pH levels.
Ground Level: The power of seeing and the crutch of complexity
“Seeing is believing” is a common cliché applicable to the adoption of technology in agriculture. Adoption rates of autosteer, sectional control and weigh cells in grain carts and air-seeder tanks are incredible. Auto guidance adoption, for example, was well above 50 per cent in the U.S. as of 2019 (McFadden et al., 2023). Nowadays, it […] Read more
Digging into the cause of poor yields
Did drought, fertility issues or something else lead to that poor crop? We look at the possibilities
Your client’s crop yielded poorly, and they assume it was due to drought. But you suspect it may be a fertility issue. How can you accurately diagnose the problem? Let us first examine what dry and drought mean. A dry year means reduced crop growth and reduced nutrient uptake, since biological, chemical and physical processes […] Read more
Sorghum sudangrass may help soil beat back diseases
The crop’s benefits for farmers are piling up, but be aware of some drawbacks, experts say
Researchers have found potential in sorghum sudangrass — a hybrid of sorghum varieties — as a fungal disease-fighting, soil-enriching grass for cover crops. Although the research was conducted in Prince Edward Island, some say there may be applications for Western Canada as well — including potential as highly-nutritious cattle feed. Two Agriculture and Agri-Food Canada […] Read more
How to make P management more sustainable
Phosphorus deficits are a problem on many Prairie farms. A Manitoba crop nutrition expert explains why — and has suggestions for what can help
Phosphorus has always been an essential nutrient in crop production. Maintaining the right P balance — ensuring there’s enough of it to sufficiently feed crops, but not too much of it so it runs off fields or seeps away to contaminate water bodies — is an ongoing challenge for Prairie farmers. Manitoba crop nutrition expert […] Read more
Crop residues’ rewards versus risks
Leaving crop residue after harvest can be beneficial — but poses some challenges
John Berger marked the completion of his 57th harvest on his family farm near Nanton in southern Alberta this fall. By most accounts, it was another productive year on Berger’s 5,000-acre grain farm. Still, something didn’t sit quite right with the long-time farmer. Whenever he toured the nearby countryside post-harvest, he noted many farm fields […] Read more
