Direct seeding and continuous cropping have meant plant residues are returned to the soil every year.

Soil organic matter and carbon sequestration

Changes in cropping practices over time have significantly improved soil quality

Prairie farmers have done an excellent job shifting to direct seeding, continuous cropping, using much more diverse crop rotations and fertilizing crops adequately, along with various other good agronomy practices. This has very positively improved soil organic matter levels and improved soil health across all the soil zones of the Prairies.





Adding wood ash to soil both practical and cost-effective

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.

Don’t join the clubroot club this year

Avoiding serious canola yield loss to clubroot will take a multi-pronged strategy

After a string of dry years, the wetter conditions in 2024 saw clubroot hit Alberta hard. Genetic advances in resistant varieties have certainly helped — but clearly the disease isn’t going away. At the CropConnect Conference last month in Winnipeg, Dr. Stephen Strelkov, a University of Alberta professor of plant pathology, provided an update on […] Read more



A soil scientist collects a sample from a test plot. The zero- to six-inch depth should be sampled separately from deeper samples to accurately determine P fertilizer requirements.

Understanding soil phosphorus, Part 2: Soil testing for plant-available P

Agronomy Management: The proper test for your soil and region can help answer questions your plants’ roots will ask this season

In my previous Grainews article, I discussed soil phosphorus (P) cycling in soil, effects of crop rotations and fertilizing on soil P, and how crops take up soil P. In this article I’ll discuss soil tests used to estimate plant-available P. Next issue, we’ll discuss how to develop wise phosphate fertilizer recommendations for your farm. […] Read more

Restore productivity on your eroded knolls

Landscape restoration, cover cropping, residue redistribution and adjusting crop inputs are some management practices that can help

The eroded knolls or hilltops common in Prairie farmland are typically the least productive, often yielding considerably less than other parts of a field. Curtis Cavers, an agronomist with Agriculture and Agri-Food Canada based at Portage la Prairie, Man., says there are ways to boost crop productivity in these problem areas. Cavers provided an assessment […] Read more
