Greg Gunthorp has been raising pigs for as long as he can remember on his family farm near LaGrange, Indiana. The Gunthorp family has always raised pigs on pasture, resisting pressure to modernize when confined animal production really took off in the pork industry in the 1980s. Just after Greg and his wife Lei took over the family pork operation in 1995, pig prices hit historic lows following an especially intense period of consolidation in the industry. At that time, with pork processors paying fourteen cents a pound for live hogs, Greg found himself selling hogs for less than his grandfather had decades ago.

Greg did not want to be the last in a long line of Gunthorps to grow pigs, so he began thinking about how to reach higher-value markets. Greg believed that the growing consumer interest in local foods and pasture-raised meats on both coasts would eventually spread to the Midwest. Greg knew he could raise high-quality pork on pasture and he knew he could market it. He also knew access to processing would be a challenge, because of the concentration in the pork industry. So in 2002, Greg built a USDA-inspected processing plant on his farm, one of only a handful in the country.

Today, Greg grows and processes pasture-based pork and poultry on 225 acres of farmland managed as perennial pasture, annual forages and grain crops. Pork and poultry are outside year-round and are protected with portable huts and electric netting. The livestock are rotated through pastures, the forage and grain crops, and a small woodland. Feed grains are grown on the farm or sourced from neighboring farms, including those of his parents and a brother. The woodland and standing corn also provide some shelter and forage for the pigs in late fall and winter and Greg encourages mulberries in the woodlands and along fence lines because of the high feed value of the fruit.

The Gunthorp Farms production system is designed to work with seasonal weather patterns. “We try not to start too early in the spring on the birds,” Greg explains, “and we don’t go way too late into the fall because of how difficult it becomes for us to make sure that they’ve got water. We try to focus production during the time of year when the pasture and forages are growing well so that the animals are on better pasture. We try to time our production to what nature does.” Greg views the high soil quality on his farm as an additional plus for production as well as a buffer against more variable rainfall. “We raise a few crops, but our soils are relatively high in organic matter, even though we’ve got sandy soils, because we have so much pasture. Our soils are more resilient to heavy rainfalls and more erratic rainfall patterns.”

Although the processing plant has been the key to the success of Gunthorp Farms, Greg admits it is a lot to manage at times. “I always tell people we really have three businesses,” he says. “We have a farm, a processing plant and a meat distribution company. In order for our model to be successful, all three of them have to function relatively efficiently and work together. We slaughter and process our own pigs, chicken, ducks and turkeys. Depending on the time of year, we have eight to twelve full-time employees for our processing plant. We do slaughter, raw fabrications of chops, roasts, steaks, chicken breast and primals. We also do ground products and sausages. We have a smokehouse and we do our bacon in there, as well as some smoked hocks, a few smoked hams and smoked sausages.” Greg also does some custom slaughtering for other local livestock producers on occasion. Gunthorp Farms meats are direct marketed through an on-farm store and weekly deliveries to more than 150 high-end restaurants and meat markets in Chicago, Indianapolis and Detroit.

The processing plant has a number of energy and environmental conservation features, including a constructed wetland for wastewater treatment, solar thermal preheating for the hot water used in processing, heat recovery from the refrigeration units and geothermal space heating. Solid waste from the processing plant is composted with crop residues and returned to the pastures and croplands. Greg is pleased with his efforts to recycle wastes and conserve energy in the processing plant. “We really work on it,” he says. “We’re doing a few interesting things. It’s kind of neat actually and it is a lot of fun. I like to play around with alternative energies.”

Thinking about weather challenges, Greg says that extreme weather is pretty much a normal part of farming in his region. “Blizzards would definitely be on the list of weather challenges,” he says, “along with drought, summer heat waves and very heavy rains. Excessively high winds can make it hard to keep our shelters from flying away, but blizzards top the list, because they can make it really difficult to get to the animals and make sure that they have feed, water and a dry, draft-free place to sleep. It’s more the getting to them than anything, because the snow and then the drifting snow can cause us to get stuck going out there. Then it gets cold enough that you can only stay out in it for a little bit.”

Although Greg thinks other farmers believe the weather has become more variable over the last decade or so, he can’t say that he has noticed any significant changes in patterns over his lifetime; however, he does think the spring warm-up pattern seems to be changing. “My grandpa’s rule of thumb was you didn’t throw pigs out on pasture until the last week of April because you might get a little bit of snow after that, but it wasn’t going to stick,” explains Greg. “And that is still somewhat consistent. I remember growing up, when I was really little, my grandpa always said you ‘freeze the frogs three times.’ He meant that after the frogs started singing in the spring you would get a thin layer of ice on the mud puddles and the ponds three more times. And this is the thing that is getting really weird right now. In the last twelve years, one year the frogs froze twenty-one times, and another year it was like twenty-three times. Otherwise, the frogs are just about always right on. Maybe the frogs know something we don’t.” Although some of these changes in weather have caught Greg’s attention, they have not required any changes in production practices at Gunthorp Farms.

Greg says that one of his biggest challenges with weather right now is longer and more intense summer and fall dry periods. He thinks this change may be connected to the increase in center-pivot irrigation in his region. “I’m 100 percent convinced that when all these guys around us turn on their center pivots, our rain becomes very, very intermittent,” says Greg. “It is almost like the rainfall just goes around us. I have no data to support it whatsoever, but I’m convinced that once they turn their center pivots on, the precipitation variability increases drastically. I think the humidity from the center pivots is changing the direction of fronts and precipitation. My dad used to say it all that time and lots of people used to think he was crazy, but there’s a lot more people starting to believe it.”

Thinking about the future, Greg is pretty optimistic about the continued success of Gunthorp Farms, mostly because of the high-quality natural resources in his region and on his farm. “I think we’re in a part of the country that is going to be one of the last places to be severely impacted by more weather variability,” he explains. “This is mostly because we have easy access to a lot of good-quality water. We don’t have the issues that the Western Corn Belt has with worrying about whether they’re going to end up running out of water.” In addition, Greg believes that the rolling landscape on his farm and the high-quality soils created by rotational grazing and diverse cropping help to buffer the farm from extreme weather events, as does his use of standing corn and woodlands to moderate extremes in temperatures and winds.

Greg also appreciates the accumulated wisdom developed by his family over many generations of raising pigs on pasture at Gunthorp Farms. “I think we know how to deal with weather variability in animal production,” Greg says. “We’ve always had thunderstorms. We’ve always had blizzards. We’ve always had high wind events, high rain events. We haven’t had them at the frequency that we have now, but we’ve always had them.”

Greg goes on to explain that pastured-based producers have a really different mindset compared to producers who raise animals indoors. “Pasture-based livestock producers had to build production systems that took weather into consideration from day one,” he says. “The people that put up confined livestock operations were the ones that never wanted to figure out how to deal with weather challenges in the first place. It’s a very different mindset when you are growing on pasture, because you’re managing a system that cooperates with nature rather than trying to just build something that works regardless of whatever nature does. It’s 180 degrees on the opposite end of the spectrum.”

Greg Gunthorp is active in sustainable agriculture and rural social justice issues and speaks regularly at agricultural conferences, particularly on pastured-livestock production and extreme concentration in the livestock industry, and has collaborated in research on his farm. Gunthorp Farms was profiled as one of sixty model U.S. sustainable farms and ranches in the USDA-SARE publication The New American Farmer: Profiles of Agricultural Innovation.

This story is based on a 2013 interview.

Rosmann Family Farms is comprised of 700 acres of rolling prairie lands near Harlan in west central Iowa. With help from their children, Ron and Maria Rosmann produce certified organic feed and food grains as well as beef, pork and poultry on land that has been in the family since 1939, when Ron’s father established the farm. After graduating from Iowa State University in 1973, Ron returned to manage the farm when his father retired. Ron farmed for commodity markets for about ten years, but became uncomfortable using chemical fertilizers and pesticides because of concerns about impacts to the environment and his family’s health. So Ron reverted to crop rotations that were common when his father started farming, and found that the farm could be profitable and productive. Ron went on to become an early adopter in his region of more sustainable production practices such as diversified crop rotations, intensive grazing and the Swedish deep bedding pork production system.

Today, the Rosmann Family Farm is a certified organic crop and livestock farm. The farm integrates beef cattle and swine into a diverse five-year crop rotation designed to produce the feed needed by the livestock operations, plus feed and food grains for sale. Corn, oats, soybeans, rye, barley, turnips, pasture and hay are grown on the farm. Intensive grazing practices produce grass-finished beef from a heard of eighty-five cows and calves, and a farrow-to-finish operation produces pork from thirty sows in a Swedish deep-bedding system. The organic waste produced by the farming operations, including the manure from the hogs, is composted and returned to cropland. Ron has not purchased nitrogen fertilizer since 1982, instead getting nitrogen for his crops through crop rotation and compost. Rock phosphate is applied about once every four or five years according to soil test recommendations. Beef, pork, feed and food grains are sold through wholesale and direct markets, including an on-farm retail store, managed by Maria, that is stocked with a variety of Rosmann Family Farm products as well as goods from neighboring farms.

Thinking about the effects of weather variability and extremes on farm performance over his lifetime, Ron says that there have definitely been some changes in recent years. More heavy rainfall and extreme weather, particularly extreme temperature swings in winter, more wind and a longer growing season, have created some new management challenges. “Anything involving variability in precipitation generally is a challenge,” according to Ron, “but the worst for us is excess moisture because it means you can’t get your work done, whether it’s baling hay, cultivating, planting, harvesting, planting cover crops, you name it. Of course, that’s an ongoing problem for organic farming anyway, but it’s just been exacerbated by the increased variability.”

Other changes in weather include more wind and more extreme storms. “We never used to have tornados,” Ron explains. “I saw my first tornado when I was forty-four years old, in ’94. I’ve seen two, three, four tornados since then. And hail. We never used to have hail very much, maybe once every seven years. Now we get it a little bit nearly every year. We’re in what’s come to be called a hail belt.” Another change is that temperature extremes have become more extreme. “If you come from the Midwest or have lived in the Midwest,” says Ron, “you know we have extremes, but the extremes have gotten worse. An example is last Monday [January 2014], it was 18 below zero temperature with a 25-mile-an-hour wind. We had a 40 below wind chill. Five days after that it got up to 48 degrees.” Looking back, Ron thinks the greater temperature extremes may have started in the early ’80s, when it was common to have weeks of 50-below wind chills and huge amounts of snow. Still, the worst snow that Ron has ever experienced was in the winter of 2010. “Our cattle were out in the fields. We couldn’t get out there and when we eventually did, we had no place to feed them,” Ron recalls. “It took some pretty big equipment to get through that kind of snow because it’s the wide-open prairies out here.”

Besides such physical challenges, Ron thinks the recent extreme swings in temperature are creating novel stress for his cattle. “What is the effect of temperature fluctuation and extreme weather changes on rates of gains?,” he asks. “ I think there may be more challenges for ruminants like our cattle with weather fluctuations. It used to be that the cattle could tank up on feed because you could count on the cold spell hanging around a couple weeks,” Ron explains. “Now we’ve got 50-, 60-degree swings in a matter of days, plus you throw the wind in. That’s the biggest change I’ve seen in my lifetime. Yes, we’ve always had those variations but not happening continually. You’d have longer periods in between. These extreme swings are hard.”

Longer growing seasons have increased weed management difficulties on the farm too, particularly with one weed species, giant ragweed. It has been a long-term challenge in the low-lying areas of the farm, but in the last five years or so it began moving up the hills on parts of the farm. Ron thinks wetter weather in May and June, combined with earlier spring warm-up and the longer growing season, work together to promote the spread of the weed. He explains, “We use a ridge-till system, which is a minimal tillage system. We don’t do any spring tillage until we are ready to plant. We historically are not even thinking about planting corn until May 1, but now the giant ragweed are already getting big by then. They are a tough weed to take out with cultivation.”

Ron says that many neighboring farmers are also increasingly challenged by changing weather conditions. Giant ragweed is even more troublesome on their farms and more narrow windows for fieldwork are creating other challenges. Many of his neighbors, most of whom are industrial corn and soybean farmers, have abandoned best management practices in an effort to get their fieldwork done at all. Ron explains, “Now every farmer in this region, just about, gets all their nitrogen fertilizer put on in the fall because they’re worried about it raining all spring. They have got to get the work done when they can because they are farming huge numbers of acres with huge equipment. But the data says between 40 and 60 percent of the nitrogen that they put on their ground is lost every year to the ground water.” Ron also says that many farmers in his region are upgrading and expanding tile drainage systems in an effort to move standing water off their fields after more frequent heavy rainfalls. This increased drainage capacity will likely wash even more nitrogen out of the farm system.

Ron is concerned about adaptations like these, which many industrial farmers are making to address current climate challenges. He fears many such farmers are focused on addressing the symptoms of climate change rather than looking for root causes such as federal support for large-scale industrial agriculture. “They keep working on genetically engineered crops and so forth, without ever looking at what caused the flooding or extreme drought in the first place. They just don’t consider the big-picture issues or how the system is creating these issues.” Ron goes on, “I found that out loud and clear this past fall [2013] when I was on a panel about the World Food Prize. There was a big biotech farmer on the panel who suggested to me that our farm system isn’t sustainable because it can’t be scaled up. I found out later that he and his brother were paid $2.3 million in farm subsidies over a thirteen-year period, which was the most of any farm in that county. And he has the audacity to say that his system is sustainable.”

Thinking about his farm as a whole, Ron says, “A testimony to the resilience of our farm system is the fact that we have never lost a crop to pests in thirty years now of no pesticides. We have never even come close to having insects or disease or anything destroy our yields. We’ve had stable, very good yields during all that time. That’s always something that people tend to look at you with, ‘Huh? I find that hard to believe.’ People don’t believe it. Of course, I’ll be the first to say we have a lot of things we could be doing better, but still, overall, the resilience shows itself in our system. Our soil quality shines here. It really does. And we work to enhance those ecosystem services, as they’re called, by continually planting more trees, more shrubs, more crops for pollinators, more windbreaks and more wildlife habitat. The diversity is what will continue to play a big role for us.”

In the future, Ron would like to move away from annual grain crops and incorporate more perennial nut, fruit and berry crops, both as food and as forages for livestock. He is inspired by Mark Shepard’s work adapting perennial cropping systems to Minnesota prairie landscapes. Ron explains, “That’s the kind of thing I would ideally like to do. But right now I’m going to put an emphasis on more water quality buffers, increasing the diversity of our headlands, getting more pollinator plants out there and planting more trees. Right now we have two and a half acres of managed woodlands, a diverse plantation that I planted with eleven different species on it.”

Over the years, Ron has engaged with diverse audiences on sustainable agriculture and rural community issues and the Rosmann family have welcomed numerous tours, visitors and research collaborators to the farm. Ron is a founding member of Practical Farmers of Iowa, a farmer-driven research and education organization, and has been active in the Organic Farming Research Foundation as a member, board member and president. In 2006, the Rosmann family received the Spencer Award for Sustainable Agriculture, which recognizes Iowa farmers who have made significant contributions toward the stability of Iowa farming. In 2012 the Catholic Rural Life Conference presented Ron and Maria with the Isidore and Maria Exemplary Award, which honors a rural couple who exemplify fidelity to a vision and vocation of rural life that combines family, stewardship and faith.
