DES MOINES, Iowa — The U.S. is coming off the wettest 12 months on record, and Iowa farmers are being encouraged to boost conservation practices to help them adapt.

Too much rain has kept many farmers out of their fields this spring, at a time when U.S. farm income already is projected to drop 45% below a 2013 high. Agronomy professor Gene Takle at Iowa State University said Iowa's weather is significantly affected by the Gulf of Mexico jet stream, which will bring excess moisture to the state for the foreseeable future.

"Physics is very clear that this jet is getting stronger,” Takle said. “And so it's a natural consequence that our climate in the Midwest should be linked to increasing rainfall."

The National Oceanic and Atmospheric Administration said the period between May 2018 and April 2019 was the wettest 12 months since record-keeping began in 1895. The Center for Rural Affairs has encouraged farmers to adopt preventive measures, such as wetlands, grassed waterways and cover crops.

Iowa has experienced excessive rainfall almost every year since 2010, according to Rural Affairs policy associate Kayla Bergman. She said preventative measures such as cover crops can provide a work-around and improve soil health to better hold the moisture.

"If you do not hay or graze that cover crop this year, so that the soil is not washing away throughout the rest of the spring and summer, even though it's not a cash crop, you just have something on the ground,” Bergman said.

The federal government has promised financial aid to farmers harmed by the trade disputes, but to qualify they had to plant a crop. Takle said that puts many between a rock and a hard place.

"Not only will it be whether they should plant corn or soybeans because the markets are fluctuating on the basis of the tariffs, but then if they get a supplemental payment they might plant for the wrong reason - they might plant for the rebate - and that's not good farming. And they don't like that either,” Take said.

To date, corn planting is 68% complete, in contrast to 97% at this time last year; while only 40% of soybeans are planted compared to 87% this time a year ago.

Minnesota will soon hold public hearings on proposed water permit changes as it seeks to get control of nitrate pollution from industrial farms.

This week, the Minnesota Pollution Control Agency released its plan to overhaul standards for a pair of water permits issued to the largest animal feedlots in the state. The main focus is livestock operations in areas vulnerable to groundwater pollution. The farms would have to adopt certain practices related to manure application in the fields.

Joy Anderson, supervising attorney at the Minnesota Center for Environmental Advocacy, calls the plan a commonsense approach to a pervasive problem. She hopes the public takes notice of what is happening.

"People who care about Minnesota's drinking water, people who care about the swimability and fishability of our water," Anderson explained.

Organizations like hers urged residents to speak up during public hearings scheduled for July. Comments can also be submitted to the agency until Aug. 9. The proposed changes are expected to face strong pushback from those representing so-called factory farms. Despite the hope from plan supporters, the changes would only apply to about 5% of livestock feedlots in Minnesota.

Past efforts to enact modest permit changes resulted in outcry from industrial ag interests. Anderson admitted the proposed changes cover a limited number of farms but added they send a signal regulators realize the scope of the contaminated water crisis linked to nitrate pollution.

"This is sort of a first step," Anderson asserted. "It tells us the MPCA is at least a little serious about making some changes."

Her group hopes what is unfolding now leads to rule changes covering all the state's 17,000 feedlots, also known as concentrated animal feeding operations. This week's move follows a recent order from the federal Environmental Protection Agency for Minnesota to clean up contaminated drinking water in the southeastern part of the state, caused by farm runoff.

The U.S. House of Representatives will likely vote this summer on a version of the Farm Bill, which passed through the committee process last month.

Some farmers and ranchers are concerned about cuts to climate-smart programs, including the Environmental Quality Incentive Program, which distributed more than $31 million to South Dakotans last year. The program and three others have been funded by Inflation Reduction Act dollars since 2022, when President Joe Biden approved nearly $12 billion for the national programs over four years.

It could change under the House version of the Farm Bill, which instead proposes increased subsidies for large-scale operations.

Tanya Svec, a member of Dakota Rural Action who helps run her in-laws' small cattle farm in Deuel County, which received a grant this year, said it is appropriate the program provides opportunities for small-scale farms to get grants, rather than just the large-scale operations policy tends to favor.

"That's really helpful for those small economies and keeping things local and building some resiliency into the farming communities," Svec explained.

Svec pointed out the business is currently finalizing a grant to fund a water system to help the operation with rotational grazing, a practice benefiting landscapes by letting some pastures rest while others are in use. It allows native plants to grow and protects watersheds. Demand for the program exceeded supply in 2023. Of the nearly 1,500 South Dakota applicants, only 27% were accepted, according to a report from the Institute for Agriculture and Trade Policy.

Svec observed more people sought out her farm's beef during and since the pandemic, which exposed supply-chain issues. She sidesteps big industrial distribution by marketing directly to customers.

"We like to raise cattle in a particular way," Svec stressed. "It's hard to be rewarded for going the extra mile for not using antibiotics, for grass-fed grass-finished beef if you remain in the standard agricultural system."

When Minnesota farmers watch their crops grow this summer, some will monitor land that has better soil health. It's because of a fairly popular conservation tool, and supporters are calling for more "real-time" data to measure progress.

Cover crops are plants grown between commodity crops to prevent soil erosion and nitrates from flowing into nearby waterways, harming water quality and natural resources. In recent years, Minnesota has emerged as one of the better-performing states for participation.

Jon Stevens has adopted the practice for his farm operation north of the Twin Cities.

"There's been years that we've just phenomenal corn yields while you're standing in 10 to 12 inches of beautiful oat grass," he said, "and we did it with reduced fertilizer inputs."

Stevens said that's good news for local creeks that connect with the St. Croix River.

The latest Census of Agriculture, released this year, showed a 17% increase in cover-crop acreage compared with 2017. The growth rate has slowed, however, and the report only comes out every five years. The National Wildlife Federation and other groups want to see a more consistent national effort to track participation, making it easier to guide assistance.

Federal programs administered by the U.S. Department of Agriculture help cover expenses for farmers who agree to plant cover crops. Stevens said they have become more flexible, but he suggested certain types of messaging to convince those still on the fence.

"Sign up a five- or ten-acre parcel [of land] and get your cover crops perfected on that five or 10 acres," he said, "and then you can just step into full-scale."

Stevens indicated that approach might help avoid turning off farmers who run into obstacles after making big cover-crop investments. There's also research indicating this practice doesn't always translate to higher yields, but Stevens said that way of thinking needs some fine-tuning.

"We've been taught decades of 'maximize your yield,'" he said, "and it's like, 'Nope, that system doesn't work that way.' You're going to reduce tillage costs."
