“Corn is one of the biggest contributors to the dairy industry, both in corn silage crop and a corn grain crop, which is also used for foraging,” said Harkirat Kaur, a corn agronomist with UW-Madison Division of Extension Crops and Soils program. Harvesting grain differs from producing silage because it focuses on using the corn plant’s kernels for human food and animal feed, as well as the basis for ethanol biofuel.

Fishing plays greater role on Midwest fish populations than warming, study finds
Despite worries over rising temperatures, it turns out anglers have a greater effect on fish populations than global warming. That’s according to a new study led by the University of Wisconsin-Madison.
“We found that for the majority of the populations so far fishing has far more greater impact than warming on the fish populations,” said Luoliang Xu, postdoctoral researcher at UW-Madison’s Center for Limnology.
Wisconsin’s successful cranberry industry won’t be immune from Trump’ tariffs, growers say
Wisconsin’s cranberry industry generates nearly $1 billion annually and supports over 4,000 jobs in the state, according to the University of Wisconsin-Madison Division of Extension. While 2025’s production of the fruit saw a slight decrease from the 6.01 million barrels harvested in 2024, the forecasted 5.3 million barrels will make up roughly 65% of the total U.S. supply.
Record crop yields won’t lead to financial security for Wisconsin farmers this year. Here’s why
In Wisconsin, grain farmers will likely face negative margins in 2025 as expected prices for corn and soybeans are below the estimated break-even points for Wisconsin producers, according to projections by the University of Wisconsin-Madison Extension.
Do you know a farm MacGyver? Or a Dairyland Darling? Wisconsin farmers redefine stereotypes
In Wisconsin, there were 37,600 women farmers in 2022, accounting for 35.5% of the state’s total producers, according to the University of Wisconsin–Madison. However, some people have a hard time believing that.
Trump’s tariffs are hurting the people who voted for him
“The tariffs are an insult to injury,” said Paul Mitchell, a professor of agriculture and applied economics at the University of Wisconsin-Madison.
Mitchell says farmers are now quietly rethinking the Trump administration’s strategies.
“We already have enough problems,” as he puts it. “Why are you making more for us?”
Dairy farmers discuss ongoing farming struggles at World Dairy Expo
Wisconsin is welcoming guests from around the globe as the 2025 World Dairy Expo is now underway in Madison.
According to a report from the University of Wisconsin-Madison Extension Farm Management program, Wisconsin exported $3 billion of agricultural products in 2024, making agriculture a major economic driver for the state.
Got cheese? UW-Madison’s Badger Cheese Club hosts first meeting of semester
One of the University Wisconsin-Madison’s largest student organizations packed a lecture hall in Ingraham with over 200 students in attendance last week. The Badger Cheese Club’s goal is to bring Wisconsin’s cheese culture to their 500 official members.
The club of cheese connoisseurs — established in 2006 — offers its members a smorgasbord of cheese each meeting, educates its members on the differences between all the unique types of cheese made in Wisconsin and builds a strong community among its members with a variety of special events.
From ‘ideal’ to ‘terrible,’ apple harvest quality varies wildly for growers across Wisconsin
Amaya Atucha, a professor and chair of the department of plant and agroecosystem sciences at the University of Wisconsin-Madison, says many apple growers in northeast Wisconsin are reporting less-than-ideal crops.
“After a cold winter caused potential damage to apple trees, cool spring temperatures led to delayed and slower pollination, resulting in smaller crops in some orchards in Northeast Wisconsin,” Atucha said in her scouting report.
This UW-Madison professor wants cows to chill out
UW-Madison professor Jimena Laporta Sanchis wants to help dairy cows beat the heat.
While a 70-degree day is welcome news to most Wisconsinites, it’s approaching a heat danger zone for dairy cattle. Due to cows’ much larger bodies and the immense work they must do to process food through four stomachs and produce gallons of milk daily, they’re more prone to overheating and increasingly vulnerable to climate change.
Wisconsin’s tiniest livestock — honeybees — are threatened by mites, pesticides and lack of food
“Honeybees are like livestock,” Hannah Gaines Day, a University of Wisconsin-Madison researcher who studies how pollinators interact with the environment and agricultural operations, told WPR’s “Wisconsin Today.” “They’re like little, tiny livestock that the beekeeper is taking care of, and so they have someone looking out for them and feeding them and giving them medicine if they need it if they’re sick. But the wild pollinators don’t have that.”
Report warns Trump administration policies are undercutting economy and Wisconsin workers
Laura Dresser, a co-author of the report and High Road Strategy Center associate director, said in a statement that the 2025 data shows “some real strengths for working Wisconsin owing to the strong recovery from pandemic shutdowns.”
“Long-standing inequalities are still with us, and federal policy puts substantial clouds on the horizon,” Dresser said. “I’m especially concerned about the administration’s attacks on the integrity of federal economic data.”
Massive Illinois salmonella outbreak 40 years ago highlights risks of raw milk as nation debates unpasteurized dairy
John Lucey, director of the Center for Dairy Research at the University of Wisconsin-Madison, said there’s no convincing evidence that raw milk offers tangible nutritional or health benefits when compared with the pasteurized product. But even with the best dairy practices and sampling of milk, the risk of illness is far greater, he said.
“A high percentage of the people who get sick are children,” he said. “That’s the thing that really disappoints me. And scares me.”
How to divide perennials in fall for bigger blooms next year
Johanna Oosterwyk, manager of the University of Wisconsin-Madison’s instructional D.C. Smith Greenhouse, says that in general, fall is a great time for planting divided perennials, since the weather is cooler and there is usually plenty of rain to help plants establish. “This applies to digging up and dividing existing plants as well as planting new ones,” she adds.
More heat, more humidity, more rain, more floods, more tornadoes — and more bad air
“So far, Wisconsin’s summer has been warmer than average and also wetter than average,” said Amanda Schwabe, a climate outreach specialist with the Wisconsin State Climatology Office at the University of Wisconsin-Madison. “Across the state, we’ve been about two degrees warmer than the average and the state has also been about 25% wetter than average.”
An invasive, edible mushroom is spreading across southern Wisconsin
An invasive mushroom is spreading across southern Wisconsin and North America, severely reducing the biodiversity of other fungi, according to a new study led by a University of Wisconsin-Madison researcher.
Aishwarya Veerabahu and a team of mycologists from UW-Madison and USDA Forest Service studied the edible golden oyster mushroom, which was brought from East Asia to the United States by mushroom cultivators in recent decades and has spread in the wild.
Hungry Japanese beetles are a formidable foe for Wisconsin vineyard owners
Christelle Guédot, a fruit crop entomologist and extension specialist in the Department of Entomology at the University of Wisconsin–Madison, says that Japanese beetles were once the bane of gardeners and farmers in the southern half of the state, but their range has since spread northwards.
“Over the past 10 years, they have been detected by the Wisconsin Department of Agriculture, Trade and Consumer Protection up in Bayfield. We also trap many hundreds in Spooner and we see them now in Door County,” Guédot said. The beetles have also been wreaking havoc in the northeastern counties, including Oneida and Vilas.
Immigrant workers deserve legality, not further persecution
According to the Applied Population Lab at the University of Wisconsin-Madison, Green County, where Monroe is located, has experienced a 229% increase in Latinos from 2000 to 2019. That growth has not been accompanied by a surge in murders, robberies, pet-eatings or any other crimes that the current administration has leveled against migrants. Instead Monroe has seen a rise in the number of Mexican restaurants and bilingual masses at the local Catholic church, as well as hardworking community members hoping to make a better life for themselves.
New research tool installed at Dane Demo Farms
Dane Demo Farms, a collaboration between local farmers, USDA Natural Resources Conservation Service, Dane County Land & Water Resources Department, and the University of Wisconsin-Madison Division of Extension, provides opportunities for farmers to directly research local impacts of conservation practices.
Wisconsin dairy farm count keeps falling amid hard times. Here are some farmers who persevere
Wisconsin lost thousands of dairy farms in the ‘90s. At one point, farmers received inflation-adjusted milk prices that were 20% lower than in 1960 and about half of the peak price in 1979, according to the University of Wisconsin-Madison Extension.
‘There’s gonna be some pain in the meantime’: Wisconsin farmers react to tariffs
“Tariffs, either on our part or on the part of our export market destinations, are not helpful for farmers in Wisconsin,” Chuck Nicholson, an agricultural economist at UW-Madison, said. “The longer we keep them in place, the bigger the negative impacts will be.”
Air quality alerts bring mixed bag for local crops
“Precipitation for the most part has been maybe a little bit above normal, but not that much,” said Jerry Clark, the regional crops and soils educator at UW-Madison Extension in Chippewa County. “We’ve just had several high humidity, lot of moisture, precipitation days.”
They’re here. They’re queer. They’re farming. New generation of LGBTQ farmers more visible and vocal.
Michaela Hoffelmeyer, an assistant professor of public engagement in agriculture at the University of Wisconsin-Madison, recalled interviewing early-career queer farmers who worried that valuable internships and apprenticeships would place them in hostile work environments or unsafe communities.
Queer farmers may also be forgoing good farmland because they want to avoid harassment, Hoffelmeyer said.
What’s your favorite farmers market?
A recent survey by UW-Madison shows that 80% of Americans say they go to a farmers market at least once a year.
Around 40% of farmworkers are undocumented, according to USDA data. Here’s what that means
One study by the University of Wisconsin-Madison found there are “no official statistics on the number of unauthorized immigrant dairy workers.”
“Estimates range from 46 percent; to as high as 90 percent, with the most used estimate being 70 percent,” the report said on Page 11.
Beetles and weevils and moths, oh my! How to fight Wisconsin’s invasive insect
The University of Wisconsin-Madison Insect Diagnostic Lab, created in 1978, supports the public and local county extension offices by receiving and analyzing several thousand insect samples each year. Every year, about two or three non-native insect species are discovered in Wisconsin. Some are only annoyances; others bring serious trouble. The latter is the case with the viburnum leaf beetle.
In Wisconsin, the beetle was first discovered in 2014 in counties west of Milwaukee. In 2019, UW-Madison entomologist P.J. Liesch, on a walk with his family, found an infested shrub. This spring, Liesch fielded dozens of questions from gardeners asking about it, as did Lisa Johnson, a Dane County Extension horticulture educator.
Why is the Trump administration focused on undocumented immigrants, not their employers?
While the Wisconsin dairy industry is known to rely on unauthorized workers (it’s believed about 70% of the workforce is working illegally), the majority in the state actually work elsewhere, said Laura Dresser, a labor economist at the University of Wisconsin-Madison.
From Dresser’s perspective, undocumented workers are especially vulnerable when law enforcement agencies focus more on immigration status and less on violations of workers’ rights.
That culture of fear can create “incentives for some employers to find a way to drive wages and standards down,” Dresser said.
Experts sound the alarm on new invasion threatening Christmas tree farms
The aesthetic damage is more than just cosmetic. “It’s the most common sawfly found infesting landscapes and Christmas tree plantations,” according to the University of Wisconsin, which notes these sawflies thrive in pines like Scots, red, Jack, and Mugo—common species in holiday tree lots.
Cool spring has given way to a warm, wet growing season for Wisconsin crops
During a recent training session for crops and soils specialists, plant pathologist Damon Smith with the University of Wisconsin says growers are experiencing weather that is ideal for corn tar spot infection.
“It’s too early to see symptoms now,” he told them, “but it is likely that infections are occurring and that growers need to be vigilant in their scouting of susceptible fields in coming weeks.”
Here’s how a $200,000 USDA grant aims to boost central Wisconsin farmers’ markets
The grant-funded research will also send University of Wisconsin students to farmers’ markets in Marathon, Portage, Wood, Waupaca and Adams counties this summer through summer 2027 to collect data on things like where are people visiting from, how much money do they intend to spend at the market and other area businesses, and what they love about farmers’ markets, Haack said.
Dairy cows tested for avian flu ahead of WI fairs
“With county fairs, there’s always a lot of movement of cattle whether it’s within the county or if there are open shows,” Jerry Clark, a crops and soils educator with UW-Madison’s Division of Extension, said. “These cattle are moving across county lines and so it’s just another way that fairs are doing their part.”
Story of agriculture is best told by those who live it says Alice in Dairyland Halei Heinzel
One of the greatest privileges of serving as Alice was working with the Dairy Innovation Hub, a collaboration between UW–Madison, UW–Platteville, and UW–River Falls. This partnership allowed me to highlight the incredible research being done in dairy science, from improving sustainability and animal health to advancing food safety and agricultural technology. These researchers and students are writing the next chapter of our state’s agricultural legacy, one data set at a time.
‘We know what to do’: Wisconsin fairs continue bird flu testing requirements for cows
Keith Poulsen, director of the Wisconsin Veterinary Diagnostic Laboratory, said the impact was disappointing last year, especially given the amount of work exhibitors put into getting an animal ready for show.
“I’m hoping that with one year of experience under their belt, they feel more comfortable to be able to submit that testing and make sure that we have robust cow classes in these shows,” said Poulsen, whose lab processes all of the avian flu samples taken in the state. “It’s part of our culture, and we missed that last year.”
Trump cuts to NOAA, NASA ‘blinding’ farmers to risks, scientists warn
The effect on U.S. forecasting will be “like losing your eyesight: slow and torturous,” said Jonathan Martin, a professor of atmospheric sciences at the University of Wisconsin.
Americans who have grown up amid the “unheralded revolution” of ever-more-precise weather forecasts will find themselves in a world growing blurrier — even as the weather grows ever more volatile, Martin added.
As ICE raids on agricultural businesses ramp up, farmers and workers are growing uneasy
Both large and small dairy farms in Wisconsin depend on immigrant laborers to fill positions that go unfilled by local workers. Undocumented workers perform an estimated 70% of the work on Wisconsin’s dairy farms, according to a University of Wisconsin-Madison School of Workers study.
Leslie Schroeder’s flax-to-linen dream weaves its way into Wisconsin

UW-Madison professor predicts new tariffs will cost dairy farmers a quarter of their income
University of Wisconsin-Madison agriculture and economics professor Chuck Nicholson explained why the Trump administration’s recent tariffs will lower the price of milk while slashing incomes for American dairy farms, harshly impacting Wisconsin’s dairy industry.
Envoys from UW-Madison CALS engage with dairy, crop industries in Thailand
When a Thai princess was looking to reinvigorate her country’s dairy industry, she quickly turned to the University of Wisconsin-Madison for help. The UW-College of Agricultural and Life Sciences answered her invitation with experts from the departments of animal and dairy sciences, and biological systems engineering. They, with financial support from Thailand, recently put their boots on the ground to start an exchange of ideas that will benefit both nations.
Wisconsin celebrates Dairy Month as state trade exports reached $8.2 billion last year
Chuck Nicholson is an associate professor of agriculture and economics at the University of Wisconsin-Madison. He said 20% of the milk produced ends up outside the U.S.
Nicholson said he doesn’t expect the dairy export market with China to be significantly impacted for the time being and that’s a good thing for Wisconsin.
“Cheese is definitely important as an export product, and it’s obviously quite important in Wisconsin. The other part about that is that with cheese typically comes whey, and we’re also a major exporter — from the State of Wisconsin — of whey products, and China is also a major market for our whey products as well,” Nicholson said.

Everything you need to know about bird flu
A dangerous bird flu, in other words, was suddenly circulating in mammals — mammals with which people have ongoing, extensive contact. “Holy cow,” says Thomas Friedrich, a virologist at the University of Wisconsin–Madison. “This is how pandemics start.”
Survey finds Wisconsin farmers value sustainable practices
A recent survey of Wisconsin’s farmers found that 56 percent of them believe climate change is happening. Another 26 percent think it isn’t happening, and 18 percent are unsure.
Michael Bell, the University of Wisconsin-Madison professor who helped conduct the study, said attitudes and behaviors don’t always match up. Bell found encouragement in how the farmers are acting, not their beliefs. The same survey asked farmers if they are practicing any of 15 different sustainable agricultural practices.
Federal cuts threaten Wisconsin farm safety center for children, rural communities
“Without the continued research that’s made possible with federal funding, it would set us back,” said John Shutske, an agricultural safety and health specialist at the University of Wisconsin-Madison. “We’ve seen over the last several decades a pretty dramatic decrease overall in our farm fatality rate. And while I think [the number of deaths] would probably plateau, I don’t think we would be able to continue to make the kind of progress that we’ve had.”
The Trump administration pauses a moonshot push to grow biofuel crops with less fertilizer
The University of Wisconsin-Madison ($5.5 million) would work on improving the ability of certain bacteria to deliver nitrogen to crops – and on introducing nitrogen-fixing traits into corn and sorghum.
Stretch of dry weather is a welcome change for Northeast Wisconsin farmers
Kevin Jarek, regional crops and soils educator with UW-Madison’s Division of Extension for Outagamie & Winnebago counties, noted, “If I were to go to counties like Shawano and Waupaca, especially the western parts of those counties, they get much lighter in soil. It’s a sandy loam texture, whereas here as we get closer to Lake Michigan, we tend to have a lot of clay.”
Tariffs could churn up trouble for Wisconsin’s dairy industry
Tariffs enacted under the Trump administration could have significant impacts on the agriculture industry in the U.S. and particularly on the dairy industry in Wisconsin, according to University of Wisconsin associate professor of agriculture and economics Chuck Nicholson.
“The tariffs have a number of different impacts, whether that be the tariffs we are placing on imports from other countries or the tariffs that other countries will place on us,” Nicholson said.
There’s a cheese festival in Wisconsin with a next-level cheese ball
This year, the festival is pulling out all the stops. “To kick things off on Thursday, we’re hosting the inaugural Wisconsin Art of Cheese Open—a golf outing perfect for both cheese connoisseurs and golf lovers,” says Kerr. Also on the docket: a creamery tour and tasting at Crave Brothers Farmstead and a cheese-and-wine excursion that begins with a sensory evaluation course taught by experts from the University of Wisconsin-Madison’s Center for Dairy Research.
Wisconsin remains the cranberry capital of the U.S. – a title it’s held for 30 straight years
