Despite critics, organic farming thrives in heart of US corn country

By Keith Schneider

WEST BEND, Iowa – People searching for ways to limit the toll industrialized American agriculture takes on communities, land, and water may want to make a visit to Clear Creek Acres in northern Iowa.

With just shy of 800 residents, West Bend, Iowa is barely a blip on a prairie landscape, but it has become home base for an uncommonly large expanse of organically grown crops- operations that have found success in challenging the popular convention that pesticides and other agricultural chemicals are needed to feed the world.

Towering grain bins are surrounded by close to 50,000 acres of corn, soybeans, oats and other crops grown without the use of synthetic chemicals. Farmers fertilize the land with chicken litter and hog manure and weed much of the land by hand, or with non-chemical tools, such as new laser weeders.

What’s occurred here since 1998, when farmer Barry Fehr experimented with raising chemical-free soybeans on 45 acres, is the development of the most expansive and profitable area of organic grain production in Iowa, and possibly the United States. Most of the land is farmed by multiple generations of the Fehr family. The family also manages about 3,000 organic acres in Colorado. Generating millions of dollars annually in a “sustainable income,” the success of the organic operations here in the heart of corn country defies long-held conventions about a need for chemicals in farming.

The agrochemical industry, led by Monsanto-owner Bayer, Syngenta and other global seed and chemical giants, maintains that weed killers, insecticides and other pesticides are essential to robust food production, and that a growing global population requires use of the chemicals in agriculture.

But 71-year-old Dan Fehr, who has been farming more than 50 years, says “that is debatable.”

The Fehr family farms are nearly matching the yields of crops grown conventionally, perhaps seeing only about a 10% yield decline in comparison, Fehr said. Their costs are lower because they’re not buying pesticides and the high-priced genetically modified seeds designed to be used with certain weed killing pesticides.

And the prices they reap are higher because organic crops command premiums in a marketplace where consumer demand for organic foods is climbing. About 25,000 acres of the Fehr farms in Iowa generate approximately $40 million a year in crop sales.

“The premium we got from selling organics is the key reason,” said Fehr. “The demand for organic has definitely grown a lot. That is why we do it.”

And, he added – “Nobody has died of not using pesticides. I don’t think it will hurt anything not to use pesticides.”

In Amish country, an unlikely partnership with beef giant JBS roils community

By Keith Schneider

EDON, OH – For 60 years, this one stoplight Ohio town has been known as a place where time appears to stand still. With more than 400 Amish residents settled in and around the rural community that straddles the Ohio, Indiana, and Michigan state lines, it has been common to see large families traveling by horse-drawn black buggies to and from farms where they milk dairy cows and grow corn.

Adhering to a strict religious doctrine that resists new technology, Amish farmers here spent decades largely eschewing industrial farming practices that have become common around the United States.

But that bucolic tableau of plain people earnestly cultivating the rich soil is eroding here, splintered by an industrial farm alliance between one of the area’s leading Amish farming families and JBS Foods, the world’s largest beef producer. Over the last two years, the partnership has established a mammoth vertically integrated concentrated cattle feeding operation that is confining more than 100,000 male calves and steers in large concrete, steel, and vinyl-covered feeding barns, and generating thousands of tons of solid manure each day.

The operations have prompted complaints of odor and contamination, and state investigators have found uncontained manure running off waste piles and out of barns, draining into streams and wetlands. Water samples collected by state inspectors contained high concentrations of nitrogen ammonia, a contaminant of manure. Following the inspections, regulators cited multiple farms for manure mismanagement, and issued modest penalties to some farms for failing to secure proper operating permits.

Nine Amish farms were cited for violations of manure management regulations in August alone. The state also ordered the largest mounds of manure, some towering two and three stories tall, to be removed. The cited farms are close to each other in Williams County, Ohio and are all owned by one extended Amish family.

Area residents say the manure contaminants, which are often spread on farm fields as fertilizer, are leaching into waterways, polluting streams, lakes, and the St. Joseph River. Water samples collected by two area environmental groups showed persistently high concentrations of nitrates, phosphorus, and dangerous E-coli bacteria in streams and lakes in the region. The animal waste is considered a source of the pollutants that cause an annual toxic algae bloom in Lake Erie.

Five years ago, Ohio launched a $172 million multi-year project aimed at bringing algal blooms under control by encouraging farmers to to limit contaminants coming from their farms. But with the new large feeding operations on multiple farms, the effort seems doomed, critics say.

EPA battles environmentalists in court over regulation of CAFOs and water pollution

By Keith Schneider

A coalition of environmental organizations faced off against the Environmental Protection Agency (EPA) in federal appellate court on Thursday in the latest skirmish in a long-running battle over the agency’s regulatory approach to water contamination connected to industrial agricultural operations.

The groups, led by the nonprofit Food & Water Watch, told a three-judge panel of the 9th US Circuit Court of Appeals that the EPA must strengthen its oversight of what are known as concentrated animal feeding operations (CAFOs).

The agency is unlawfully allowing roughly half of the nation’s more than 20,000 big livestock and poultry feeding facilities around the country to operate without permits required under the 1972 Clean Water Act, the groups argued to the court. And, they said, the agency is violating the law by authorizing CAFOs to store and spread manure so haphazardly that the drinking water for millions of people is at risk as thousands of streams, lakes and other waterways are polluted with harmful bacteria, nitrates, phosphorus and other contaminants.

The agency has “failed” for more than a decade to adequately regulate these operations, Food & Water Watch lawyer Emily Miller told the court.

The hearing Thursday stems from a petition filed by Food & Water Watch and other groups in 2017 that called for the EPA to require CAFOs to obtain water quality permits and strengthen permit standards to protect waterways from the manure generated by the animal operations. The petition also urged the agency to reconsider an exemption that immunizes CAFOs from any water pollution caused by storms washing manure off of saturated fields.

The Trump administration ignored the petition. Last summer, the EPA formally denied the petition, but announced it would form a committee to recommend any changes in how the agency regulated CAFOs. Food & Water Watch, joined by four other national organizations and eight environmental groups from five states, then sued the EPA, demanding it reconsider its decision.

In the court hearing, EPA attorney Paul Cirino told the judges that the agency had initiated a detailed study of CAFO operations and pollution in January and established a study group last summer that is scheduled to issue recommendations on CAFO oversight next year. The new information, he said, would guide the agency’s actions about how to respond to the environmental groups’ concerns.

But Miller pushed back. “EPA has already spent seven years when it could have been taking its statutory mandate seriously,” she said. “Now they want some undefined amount of time thinking rather than acting.”

A court ruling on the matter could take months.

Movement to limit CAFO pollution seen strengthened by Michigan court ruling

By Keith Schneider

A recent state court decision could transform how animal agriculture is regulated in Michigan, and potentially influence how other state and federal regulators oversee the industry’s mammoth waste stream, according to environmental lawyers and activists.

The optimism from environmental advocates comes after the Michigan Supreme Court ruled on July 31 that the state’s Department of Environment, Great Lakes, and Energy (EGLE) has full authority to require industrial animal agriculture to take much stronger actions to manage the torrent of manure waste polluting waterways. The closely watched case pit the administration of Michigan Gov. Gretchen Whitmer against the powerful agricultural industry, led by the Michigan Farm Bureau.

“The decision is extremely powerful language for EGLE to act,” said Carrie La Seur, the legal director of For Love of Water, an environmental law and policy group that intervened on behalf of the state. “It’s clear that EGLE gained a lot of authority through this ruling.”

Michigan is one of many US states contending with rampant ground and surface water pollution caused by agricultural production. A key source of the pollution are the nation’s more than 21,000 large dairy, cattle, hog, and poultry operations, known as Concentrated Animal Feeding Operations or CAFOs.

The nationwide problem extends across the ocean. On Aug 9, the Center for Food Safety environmental group gave legal notification to a Hawaii “megadairy” of their intention to file a lawsuit in federal court. The allege the dairy has been illegally “discharging animal waste, solid manure, liquid manure, milk waste, and chemical pollutants” into the state’s waterways and into the Pacific Ocean.

An Iowa farm county seeks answers amid cancer rates 50% higher than national average

By Keith Schneider

EMMETSBURG, IOWA –Raised in rural Iowa, 71-year-old Maureen Reeves Horsley once considered her tiny hometown in the northwest part of the state to be a blessed space. She recalls a time when the streams here ran clean and the lake water was clear.

The family farm where Horsley grew up was one of more than 1,200 farms in Palo Alto County in 1970. In her memory, the county’s 13,000 residents enjoyed a thriving agricultural-based economy and close-knit neighbors. Cows grazed in verdant pastures. And seemingly endless acres of corn marched to the horizon.

“We had good crops, corn and soybeans,” Horsley said of her family’s farm along the West Fork of the Des Moines River. “You could make it on a small amount of farmland. You felt safe. It was a good life.”

Two generations later Emmetsburg and Palo Alto County have been radically transformed into a place where many residents worry that the farms that have sustained their livelihoods are also the source of the health problems that have plagued so many families.

Horsley, a certified nurse practitioner who still lives in the county, is among many Iowa residents who ask whether the farms that make up the lifeblood of Iowa’s economy have become a source of disease and death due to the toxic chemicals and other pollutants indelibly linked to modern agricultural practices.

“We drank the water on our farm,” Horsley said in an interview. “My sister had breast cancer. She was only 27 when she died. She grew up here. My other sister had uterine cancer. As a nurse practitioner I’m aware of five people now with pancreatic cancer. I know 20 people who have other cancers or died of cancer here. Look at the obituaries in our newspaper. Everybody is aware this is going on.”

“It’s getting worse” – US failing to stem tide of harmful farm pollutants

By Keith Schneider

VENICE, LA. Kindra Arnesen is a 46-year-old commercial fishing boat operator who has spent most of her life among the pelicans and bayous of southern Louisiana, near the juncture where the 2,350-mile-long Mississippi River ends at the Gulf of Mexico.

Clark Porter is a 62-year-old farmer who lives in north-central Iowa where he spends part of his day working as an environmental specialist for the state and the other part raising corn and soybeans on hundreds of acres that his family has owned for over a century.

Though they’ve never met, and live 1,100 miles apart, Arnesen and Porter share a troubling kinship – both of their communities are tied to a deepening water pollution crisis that is fouling the environment and putting public health in peril across multiple US states.

Arnesen’s home lies near an oxygen-depleted expanse of the northern Gulf known as the “dead zone,” where dying algae blooms triggered by contaminants flowing out of the Mississippi River choke off oxygen, suffocating shrimp and other marine life.

Porter’s farm is positioned at the center of the Upper Mississippi River Basin where streams and other surface waters saturated with farm wastes flood into the big river, and contaminated groundwater permeates drinking water wells. Cancer incidence in Iowa is among the nation’s highest, and is rising.

The culprit at the center of it all is a colossal tide of fertilizer and animal manure that runs off fields in Iowa and other farm states to find its way into the Mississippi River. The same agricultural pollution problems are plaguing other iconic US waterways, including Chesapeake Bay and Lake Erie.

US farmers use more fertilizer and spread more manure than in most other countries, accounting for roughly 10% of global fertilizer use, behind China and India. But while the nutrients contained in animal manure and fertilizer are known to nourish crop growth, the resulting nitrogen and phosphorous that end up in waterways are known to create severe health problems for people.

A grand government plan to address the problem has cost taxpayers billions of dollars with minimal results so far, and nowhere is the problem more pronounced than in the Mississippi River Basin.

The reasons for the persistent pollution problem are multi-fold, including strong industry opposition to regulations to control the farm contaminants, and a perverse system in which some government programs incentivize farming practices that add to the pollution even as other government programs try to induce farmers to reduce the pollution.

“You’re talking about systemic dysfunction,” said Matt Liebman, professor emeritus of agronomy and sustainable agriculture at Iowa State University.

New report sparks questions and controversy over possible causes for Iowa “cancer crisis”

By Keith Schneider

Amid increasing scrutiny of a potential link between Iowa farm chemicals and cancer, a new report is generating controversy as it blames rising cancer rates not on the toxins used widely throughout the state, but on something else entirely: binge alcohol consumption.

The Iowa Cancer Registry, a health research group housed at the University of Iowa, reported on February 20 that Iowa has the second-highest and fastest-rising incidence of cancer among all states. An estimated 21,000 new cancer cases are expected to develop this year and 6,100 Iowans will die from cancer, Iowa Cancer Registry Director Mary Charlton said in announcing the new report. Iowa, she said, has the highest rate of binge drinking in the Midwest with 22% of residents reporting binge drinking, more than the national average of 17%. Overall, Iowa has the 4th highest incidence of alcohol-related cancers in the US, according to the report.

“Alcohol is a known carcinogen and a risk factor for several cancers including oral cavity, pharynx, larynx, esophagus, rectum, liver, and female breast cancers,” Charlton said in a news conference.

The assessment has drawn questions and sparked doubts, however, from state leaders and health and environment researchers who have been calling for a probe into just how much the state’s agricultural industry may be contributing to the spread of disease.

“Is alcohol responsible for the increase in cancer incidence here since 2014? I personally doubt that,” said James Merchant, a retired professor of occupational and environmental health, and former dean of the University of Iowa College of Public Health.

“What needs to be looked at are things that are probable or possible carcinogens that have increased beginning about 1990, because of the well-recognized latency of environmental cancers,” Merchants said. “Those carcinogens associated with industrial agriculture are the ones that really need to be looked at very closely.”

Cancer in the corn belt sparks actions to fight farm chemical contamination

By Keith Schneider

When directors of the public water utility in Des Moines, Iowa, went to court in 2015 to try to stop toxic farm nutrients from contaminating the city’s drinking water, they knew the federal lawsuit they filed would be seen as not just a desperate step to protect public health, but also a brazen act of defiance that would provoke a ferocious response from Iowa’s powerful farm and political leadership.

As they anticipated, a cohort of agricultural interests joined then-Gov. Terry Branstad in beating back the lawsuit, which Branstad declared an act of “war on rural Iowa.”

Des Moines Water Works alleged that drainage districts in three Iowa counties had polluted the Raccoon River with nitrates, forcing costly efforts by Des Moines to render the polluted water safe for drinking. A The case was dismissed in 2017 after a court ruled that Iowa law immunizes drainage districts from damage claims.

It was the last time a government entity in Iowa or any other Corn Belt state made a focused attempt to reduce human exposure to suspected cancer-causing commercial fertilizers and a flood of livestock manure that routinely drains from farm fields into groundwater, streams, and rivers.

Until now.

Prompted by compelling research showing that cancer-related diseases and deaths are climbing as contamination from common agricultural chemicals and manure increases in key farm states, lawmakers and health officials in Iowa, Minnesota, and Nebraska are pursuing an array of new strategies aimed at reducing the risks to human health presented by the ongoing farm-related contamination.

A top concern for lawmakers and health professionals in the three states is reducing exposure to nitrates, which form when nitrogen from fertilizer and manure combine with oxygen. Babies can suffer severe health problems when consuming nitrates in drinking water, and a growing body of literature indicates potential associations that include an increased risk of cancer.

“It’s pretty obvious that in the areas where levels of nitrates and other agrichemicals in water are higher, you get more pediatric cancers and birth defects,” said Eleanor Rogan, chair of the Department of Environmental, Agricultural, and Occupational Health at the University of Nebraska Medical Center. “So that sort of tells you maybe you should do something about this and get the levels down.”

“We can’t sit back” – Amid climbing cancer rates, Iowa health officials eye farm chemicals

Faced with a startlingly high cancer rate in the key US farm state of Iowa, public health leaders are taking the politically precarious step of acknowledging that preventing disease necessitates cutting exposure to potentially cancer-causing chemicals, including those used in agriculture.

In a departure from other state cancer prevention programs, which rarely address environmental risk factors for cancer other than radon, a known cause of lung cancer, Iowa is working to better understand and make the case for limiting exposure to pesticides, commercial fertilizer, and animal manure used and generated by Iowa agriculture, among other environmental contaminants.

“These broader array of environmental risk factors are absolutely there for cancer. But they’re not paid attention to in state cancer control plans,” said Molly Jacobs, an epidemiologist at the University of Massachusetts, who is working with Iowa health authorities. “It’s quite unique that Iowa has addressed this as a priority in their plan. I applaud Iowa for taking on this task of thinking much broader and bigger, and changing this paradigm.”

The work to address environmental factors to reduce cancer cases began earlier this year and is being undertaken by the Iowa Cancer Consortium. It’s a 21-year-old, 650-member coalition of public health professionals, researchers, and health providers focused on controlling cancer. The consortium is led by Dr. Mary Charlton, an epidemiologist at the University of Iowa College of Public Health who also is research director of the Iowa Cancer Registry, which collects cancer data on Iowa citizens.

The consortium has launched an Environmental Task Force and a five-year plan for cutting public exposure to “environmental carcinogens.”

Farmers, agricultural executives, and state lawmakers have spent decades resisting any changes in farm practices that reduce the use of chemicals and nutrients, saying the inputs are needed to ensure ample food production.

But public health advocates say evidence tying the farm pollutants to disease is too strong to deny.

“We can’t sit back and say, ‘Wow. Somebody may not like this.’” said Kamyar Enshayan, director of the Center for Energy and Environmental Education at the University of Northern Iowa. “Knowing what we do know, it’s just prudent that we support practices and systems that require significantly less fertilizer and pesticides.”

US push to turn farm manure into renewable energy draws concerns

By Keith Schneider

AMES, IOWA – In a gathering that drew the attendance of both farmers and Wall Street financiers, US regulators joined with oil giant Chevron at a November conference here to promote what backers promise will be a monumental breakthrough – systemic changes that would turn polluting agricultural waste into a source of renewable energy that replaces fossil fuels and slows climate change.

Speakers at the conference, which was hosted by Iowa State University and co-sponsored by the Environmental Protection Agency (EPA) and the US Department of Agriculture, assured attendees that the answers to agricultural and climate woes can be found in technology that already exists: Key, according to conference promoters, is the rapid expansion of large methane biodigesters, which capture manure waste from the nation’s cattle, hog and poultry operations and convert it into a harvest of both public and private riches.

Water and air would be cleaner and farmers could see billions of dollars in new farm income, among other benefits, according to backers.

“It can provide a substantial portion of global energy needs,” Rudi Roeslein , CEO of Roeslein Alternative Energy, told the attendees. His company has built farm-based methane systems around the country that produce enough fuel to displace six million gallons of diesel fuel and 80,000 cars. “If we do this on a large scale in the US we could generate $63.6 billion worth of revenue for farmers around the country.”

Roeslein’s company promises on its website to “restore a balance” to farmland “by using the sustainably harvested biomass to create renewable natural gas.”

Chevron promotes its investment in manure biodigestion as “finding inspiration in nature.”

“I’m really excited about the innovation in this space,” Lisa Schulte Moore, a professor and co-director of the Bioeconomy Institute at Iowa State, said in an interview. “The renewable natural gas market is providing economic incentives for better management of manure.”

But critics argue that the emergence of an alliance of Big Ag, Big Oil, and Big Government to generate energy from livestock waste is ripe with peril. They say that air pollutants and waste discharged from farms and from already existing farm-based biodigesters receive scant federal and state oversight. They fear that without strict regulation, manure digesters could make water and air pollution worse, not better. Industrial-sized farms, including concentrated animal feeding operations (CAFOs), already are one of the nation’s largest sources of water pollution, and among the principal causes of air pollution.
