Palmer amaranth found in Ontario

It was only a matter of time before Palmer amaranth was found on a farm in Ontario. Although technically it was found back in 2007 along a rail line outside of Niagara Falls, surveillance of that area in the years following have never detected any plants since the initial finding. In late summer, an individual […]

Identifying and Addressing Soil Structure Challenges   A well-structured soil improves water infiltration, air exchange, rooting, and ultimately crop yield. On the other hand, a cloddy, dense, or compacted soil may result in ponding, nutrient losses, and restricted root systems. Poor soil structure contributes to lower crop yields, especially in seasons that are either too dry […]

Injecting anaerobic digestate after wheat harvest into a growing cover crop to maximize soil health benefits and economic value of nutrients.

Getting to Know your Manure with a Manure Analysis The “magical” qualities of manure and organic amendments for providing long-term benefits have been well documented, especially for maintaining and improving soil organic matter. Sourcing off farm manure and organic amendments has become more difficult and expensive with the increased interest in improving soil health, therefore […]

With winter wheat harvest beginning in parts of the province, cover crop seeding will be close on its heels. Adoption of cover crops has increased in Ontario over the last number of years, and for good reason – they help improve water infiltration, compete with weeds, and capture left-over nutrients. In this article, I’ll share […]

Nitrogen losses in saturated soils

Recent rainfalls have brought about an abrupt change to soil conditions in some Ontario fields in just a few short weeks ago.  Localized heavy rainfalls have left some fields with standing water in low-lying areas, while many fields are wet or saturated.  This has raised questions about the potential losses of nitrogen (N) for the […]
