How do cover crops impact nitrous oxide emissions? Cover crops help build soil carbon, reduce erosion, and can offset crop nitrogen fertilizer requirements. But when it comes to nitrous oxide (N2O) – a greenhouse gas that contributes about half the total warming effect from agriculture in Canada1 – there is a question mark surrounding their […]
Planting corn directly into a living cover crop before it is killed by herbicide or tillage is not something that would have been considered 30 years ago. However, with advances in planter technology, herbicide options, and a greater awareness of cover crop benefits to soil health, more growers are doing it. According to the 2022-2023 […]
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 […]
This article shares the findings from a 2021 on-farm trial that compared fall cover crop termination with planting green. It was conducted near Hagersville, Ontario, as part of an Ontario Soil and Crop Improvement Association Tier Two project. Highlights To watch a short video with in-season footage from the trial, click below: Background Information on […]
Jake Munroe, Mike Cowbrough and Sebastian Belliard (OMAFRA) Cereal rye (Secale cereal) has several strengths as a cover crop option. It’s relatively inexpensive and easy to kill. Rye improves soil structure, builds organic matter and helps protect against water and wind erosion. It can suppress weeds as discussed here (see Figure 1). It’s also very […]
It’s March, the snow is melting and the ground is frozen so we know what that means! Now is a good time to be considering or thinking about frost seeding some red clover into those winter wheat stands! While we can’t control all the factors that influence the success of our red clover stands in […]
Dr. Dave Hooker and his colleagues have been curious about the value of integrating cover crops into a farming operation in the long term. These questions have remained unanswered by numerous short-term trials they had been conducting, which led them to establish a new trial. As it can take time for a cropping system to […]
There are a variety of agricultural research trials in the province, but one that stands out from the rest is the long-term cover crop trial set up by Dr. Laura Van Eerd in Ridgetown, Ontario. This trial was established in 2007 and has had consistent cover crop treatments within a processing vegetable-grain crop rotation on […]
It’s the time of year when you can see the impact of erosion on farm fields across the province. Whether it’s subtle (Figure 1) or obvious (Figure 2), erosion affects soil by reducing fertility, decreasing organic matter and lowering productivity. With National Soil Conservation Week happening from April 19th to 25th, I wanted to highlight […]

We are all aware of the imperative to minimize compaction, but with crop quality on the line, tough choices have to be made on the trade-off between the grain quality and potential income from this year’s crop, and future yield and cost of production due to compaction losses or increased tillage passes. There have […]
Photo: Low cutting heights increase the odds of soil contamination in the crop. Soil contamination shows up in ash contents above 9%. This can be prevented by raising the cutter bar. Fall and Winter Conditions Rain delays in 2017 pushed harvest in some areas into the critical fall harvest period. Root reserves that contribute to […]
Join the OMAFRA Soil Team and Upper Thames River Conservation Authority for a hands-on day of learning about soil management on August 22nd. Six in-field sessions will explore a range of topics, including: Soil pits: exploring what’s under our feet Measuring soil health: in-field methods to evaluate soil structure, infiltration, and much more. “Soil your […]
Western Bean Cutworm Update Western Bean Cutworm continues to be a concern for pollinating corn in areas with high trap counts. Peak moth flight has occurred in some of the counties in the southwest but counties east and north of Middlesex and those in Central and Eastern Ontario have not reached peak yet. Moths will […]
Cover crops are well proven to help reduce soil erosion and improve soil structure. They can also have nutrient benefits. Whether you have been growing cover crops for decades or are just getting started, it is helpful to know what specific cover crops can (and cannot) do from a soil fertility standpoint. There are three […]
