Potential moneymaker, water protector sits on MN's frozen farm fields

Clean drinking water doesn't just come from replacing lead pipes. Solutions also rest on Minnesota's farm fields, and this time of year, some rural acreage has been planted with seeds designed to do winter magic before the next growing season.

Cover crops are typically planted going into in a farmer's offseason and are meant to improve soil health before a main crop, like corn, is prioritized the following spring and summer.

Peter LaFontaine, agricultural policy manager with Friends of the Mississippi River, said newer varieties of winter cover crops have come on the scene, potentially changing the dynamics when it comes to profits. On the sustainability side, protecting waterways is still a benefit.

"If you have crops that are providing some more of that natural cover during winter, you wind up with a more resilient system. These crops do a phenomenal job of addressing things like nitrogen loss," he said.

Traditional plants like cereal rye have been helpful with those water quality efforts. But products like winter camelina are getting more attention these days because they have a bigger potential as a dual benefit. They can be harvested for the sustainable jet fuel market. Overall, the cover crop movement still faces headwinds, with an adoption rate below 3% for Minnesota's farmland.

Agriculture experts say Minnesota's harsh winters can be disruptive to cover crops, and it can take time for a producer to fully realize the economic benefits of improved soil quality, such as less flooding in fields.

Anne Schwagerl, western Minnesota farmer and vice president of the Minnesota Farmers Union, has long planted these seeds and is now experimenting with the "cash cover crops." She predicts they'll help with the momentum issue.

"The old adage in farming is don't plant something you don't have a market for. Well, this is something we actually got a market for," she explained.

Schwagerl noted that the biofuels market has a strong appetite for winter camelina. There are federal conservation programs that provide incentives for using cover crops. It's unclear how much extra support will be provided as Congress debates the next Farm Bill.

Despite Minnesota's low adoption rate, more farms were trying cover crops in 2022 compared to 2017. That's according to the Census of Agriculture, released every five years.
