Does Wider Canola Row Spacing Optimize Returns… Or Risk Consequences?

Seeding canola wide can impact everything from seed cost to weed management to disease potential, but what spacing offers the best reward and least risk?

Typical row spacing in most commercial canola fields varies from seven to 12 inches. That’s higher than the six-to-eight-inch spacing used in canola’s earliest years, and much more precise thanks to today’s seeding technology.

Given new research findings and increasing agronomic understanding, is seven to 12 inches the very best option? Could a specific spacing inside that range offer maximum yield or quality benefit, or could going wider, say 15 inches or even 18, save seed while optimizing disease management?

Understanding Nitrogen Loss Through Denitrification

Video: Understanding Nitrogen Loss Through Denitrification

Denitrification is one of the three main pathways for nitrogen loss, but what is it really, and how much nitrogen do we stand to lose?

In this episode, Lyle Cowell is joined by Dr. Erin Daly from the University of Guelph to break down denitrification and the conditions that drive nitrogen loss in the soil. They explore how nitrogen can be lost as nitrous oxide and nitrogen gas, what conditions drive losses and when they are most likely to occur.

Erin also shares how CanN2ONet, a national research network, is helping us better understand nitrous oxide emissions across Canada. From field towers that measure emissions to research into regionally tailored best management practices, discover how the network is working to help growers improve nitrogen use efficiency and help reduce nitrogen losses across the country.
