When ’hopper clouds' filled the skies

 It’s been another bad year for grasshoppers in many parts of the Prairies.

Some farmers have told us that whatever crop managed to grow in this summer’s drought was eaten by the voracious insects.

The problem isn’t new, of course.

Histories of the early days of farming on the prairie, particularly in the United States in the mid-19th century, are replete with hair-raising stories of grasshopper scourges.

In fact, some of the stories are so far removed from modern encounters with grasshoppers that it’s hard to believe they are true.

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.
