Pasturing Oxbows: Optimizing Benefits to the Farm, Water and Wildlife

Jan 05, 2024

By Elizabeth Ripley

Iowa Learning Farms, in partnership with the Iowa Nutrient Research Center and the Conservation Learning Group, is hosting a free virtual field day on pasturing oxbows, Thursday, Jan. 18, at 1 p.m. Central time. Join for a live discussion with Sara McMillan, professor of agricultural and biosystems engineering at Iowa State University, and Karen Wilke, associate director of Freshwater at the Nature Conservancy.

Iowa Learning Farms is a conservation program with Iowa State University Extension and Outreach.

The virtual field day will explore an oxbow in Kossuth County, including how it naturally formed and the restoration process to date. Located within an actively used pasture, the restoration process took into consideration factors like livestock safely accessing the water. These pastured oxbows help improve overall forage production by providing a place for water to collect and reduce flooding within the pasture. Additionally, by providing a water source out of the stream, these systems improve water quality through the reduction of direct contributions of bacteria from livestock in the stream and the maintenance of streambanks that help retain sediment and phosphorus.

“When we are designing these pastured oxbows, we want to be sure that we are doing a seeding plan that will be successful for livestock and the wetland,” noted Wilke. “We’re looking for something quick to establish and stabilize those banks and that is hardy as well. When possible, we also use natives as they can be as nutritious and palatable to livestock as other types of pasture grasses.”

Video: Why Invest in Canada’s Seed Future? | On The Brink: Episode 3

Darcy Unger just invested millions to build a brand-new seed plant on his farm in Stonewall, Manitoba so when it’s time for his sons to take over, they have the tools they need to succeed.

Right now, 95% of the genetics they’ll be growing come from Canadian plant breeders.

That number matters.

When fusarium hit Western Canada in the late 90s, it was Canadian breeders who responded, because they understood Canadian conditions. That ability to react quickly to what’s happening on Canadian farms is exactly what’s at risk when breeding programs lose funding.

For farmers like Darcy, who have made generational investments based on the assumption that better genetics will keep coming, the stakes are direct and personal.

We’re on the brink of decisions that will shape our agricultural future for not only our generation, but also the ones to come.

What direction will we choose?

On The Brink is a year-long video series traveling across Canada to meet the researchers, breeders, farmers, seed companies, and policymakers shaping the future of Canadian plant breeding. Each week, a new story. Each story, a piece of the bigger picture.

Episode 3 is above. Follow Seed World Canada to catch every episode, and tell us: Do you think the next generation will have the tools they need to success when they takeover? How is the future going to look?
