A Giant Organic Farm Faces Criticism That It's Harming The Environment

In early March, wind-blown soil filled a ditch between a road and the fields of Gunsmoke Farms.
In early March, wind-blown soil filled a ditch between a road and the fields of Gunsmoke Farms.

Hardly a week goes by, it seems, without a big food company making promises to deliver products from green, sustainable farms. Turning those promises into reality, though, can be complicated.

Take Gunsmoke Farms, a vast property that covers 53 square miles just northwest of Pierre, S.D. The food company General Mills, maker of Cheerios, announced in 2018 that it would convert the farm to organic production. The company planned to turn it into an educational hub to teach other farmers "how to implement organic and regenerative agriculture practices."

Now, some of Gunsmoke Farms' neighbors say that the farm is doing more environmental harm than good.

Among the critics is Dwayne Beck, a soil scientist who manages South Dakota State University's Dakota Lakes Research Station, 40 miles east of Gunsmoke Farms. Beck was skeptical about the project from the beginning. "It scared me, because normally organic [farming] entails lots of tillage, and those soils are very fragile," he said.

Farmers often till the soil — breaking it up with tools such as chisel plows or disks — to uproot weeds and get land ready for planting. But tillage also tears soil loose from the plant roots that help hold it together and also breaks down parts of the soil that are most rich in carbon and nutrients.

This is especially true of soils where Gunsmoke Farms is located, Beck said. The area developed from an ancient ocean floor, and the soil is full of clay. "Once you disturb it, nothing holds that soil together. It just turns into powder," he said, vulnerable to rain or wind that can carry it away.

This used to happen regularly in western South Dakota. Beck recalls dust storms so thick, cars crashed because drivers couldn't see vehicles just in front of them.

Those dust storms happen less often now because over the past two decades, many farmers in the region abandoned regular tillage. They now use planting equipment that slices into undisturbed soil and places seed in the ground.

To control weeds, these farmers use herbicides. But chemical weed control isn't an option for an organic business such as Gunsmoke Farms.

During the farm's three-year transition to organic status, its managers grew primarily alfalfa, which doesn't require annual planting. In 2020, though, they planted their first crops of wheat and peas, which involved tilling the enormous fields.

Months later, Beck said his fears were realized. He collected photographs of the damage: small drifts of wind-blown soil in a roadside ditch, and a country road that disappears into a brown cloud of blowing dust. "The soil that blew out of there, it will never be the same as it was before it blew," he said. It won't have the stability and structure of healthy soil, held in place by the roots of plants.

Beck and others who live near Gunsmoke Farms said that nonorganic farmers also struggled to control soil erosion in 2020 because of drought and high winds. But the problems at Gunsmoke, they said, were worse. A planting of winter wheat, which was supposed to protect the soil on those fields, failed to grow well.

When the Gunsmoke project was just getting off the ground, in 2018, an expert from the U.S. Department of Agriculture's Natural Resources Conservation Service drew up a soil conservation plan for the farm. That plan called for wide strips of native grasses across the farm to help prevent soil from blowing, and for the steepest slopes to stay covered, most years, with crops such as alfalfa that don't require annual planting.

Gary Zimmer, an expert on organic farming who collaborated with General Mills in launching the Gunsmoke project, said that he drew up a plan that incorporated many of these measures. But he said much of his plan was never implemented.

"It's in a deep hole," Zimmer said, referring to the farm. "I don't know how you get it back out organically. It's hard to farm organically if you do it really well, and have your intensive management. But 30,000 acres, poorly managed, is a really good sign for failure."

General Mills doesn't own Gunsmoke Farms or control it directly. It signed a "strategic sourcing agreement" with an investment firm called TPG Sixth Street Partners, an affiliate of the firm TPG, which acquired the land in order to supply General Mills with organic wheat, peas and other crops. Sixth Street later became an independent operation, and it currently owns Gunsmoke. The investors have hired a series of managers to run the farm.

General Mills said in a statement to NPR that turning Gunsmoke Farms into a thriving ecosystem "is a journey" and promised continued efforts to minimize erosion and improve soil health there.

Sixth Street Partners said in its statement that the farm is "early in the process of regenerating land" and that its mission — organic farming — also provides additional environmental benefits, such as lower use of pesticides and synthetic fertilizer.

Ruth Beck, who's married to Dwayne Beck, spent many years as an extension agronomist with South Dakota State University, advising farmers in the area around Gunsmoke Farms. She said it's simply difficult to grow crops organically, on a large scale, in this semi-arid part of the country. "You know, we've got to figure out ways to do that, if that's what people want," she said. "But we aren't there yet."

At Gunsmoke, she said, environmental marketing got ahead of what farmers can actually do. Copyright 2021 NPR. To see more, visit https://www.npr.org.

AUDIE CORNISH, HOST:

Lots of big food companies are going green, promising environmental sustainability, but delivering on those promises can be complicated. And one example is an organic megafarm in South Dakota backed by the company General Mills, maker of Cheerios. Some of the farm's neighbors are accusing the farm of doing more harm than good. NPR's Dan Charles has the story.

DAN CHARLES, BYLINE: Gunsmoke Farms is huge. It covers 53 square miles near Pierre, S.D. An investment fund based in San Francisco and Texas bought it a few years ago. And General Mills announced it would help convert it to organic farming with the help of Gary Zimmer, an organic expert from Wisconsin.

GARY ZIMMER: My job as a soil consultant was to get those soils rich. We were going to fix the soil. And it was going to be quite a large investment. General Mills even took some soil to California to some show (ph) to see what it looked like today and what it was going to look like when we got done.

CHARLES: But in South Dakota, some were skeptical that it could work, including Dwayne Beck, a soil scientist who runs an agricultural research station for South Dakota State University, 40 miles east of Gunsmoke Farms.

DWAYNE BECK: It scared me because normally, organic entails using lots of tillage. And these soils are very fragile.

CHARLES: Farmers often till soil, stir it up with tools like chisel plows or disks to clear weeds and get land ready for planting. But Beck says tillage is destructive, especially where Gunsmoke Farms sits, where it's dry and the soil is full of clay.

D BECK: Once you disturb it, nothing holds that soil together. It just turns into powder.

CHARLES: It can wash away or blow away, which used to happen all the time. There were dust storms so thick cars crashed because drivers couldn't see, so most farmers in this area cut way back on their tillage. Instead, they use planting equipment that slices right into undisturbed land and places the seed into the ground.

D BECK: We'd prefer to not touch the soil at all if we can get by with it, but we have to have some way to put the seed in there.

CHARLES: To control the weeds, they use herbicides. But herbicides are not an option for Gunsmoke Farms, being organic. And last year, to get ready for its first crops of wheat and peas, those enormous fields were tilled. And Dwayne Beck says his fears were realized. He sent me some pictures.

D BECK: Yeah, that's just another picture of soil in the ditch. That's supposed to be green grass.

CHARLES: It's covered by a small drift of windblown dirt. In another photo, a country road disappears into a cloud of dust.

D BECK: That soil that blew out of there, it will never be the same as it was before it blew.

CHARLES: It won't have the stability and structure of healthy soil held together by the roots of plants. When Gunsmoke Farms was just starting, experts from the U.S. Department of Agriculture drew up a soil conservation plan for the farm. They wanted wide strips of permanent native grasses crossing the fields and crops you don't have to plant every year on the steepest hillsides. Gary Zimmer, the soil consultant, says that was part of his original plan. But new farm managers took over and never followed through.

ZIMMER: Oh, boy. Oh, boy. Oh, boy. It's in a deep hole. I don't know how you get it back out organically. It's hard to farm organically if you do it really well and you got your intensive management. But 30,000 acres poorly managed is a really good sign for failure.

CHARLES: General Mills said in a statement that turning Gunsmoke Farms into a thriving ecosystem is a journey, and it promised continued efforts to minimize erosion and improve soil health there. The investment firm that owns the farm, Sixth Street Partners, said in its statement that the farm is early in the process and that its mission, organic farming, also provides benefits like reduced use of pesticides and synthetic fertilizer. Ruth Beck, who's married to Dwayne Beck, used to work for South Dakota State University, advising farmers in this area. She says it's just really hard to grow crops organically on a large scale in this part of the country.

RUTH BECK: You know, we've got to figure out ways to do that, if that's what people want, but we aren't there yet.

CHARLES: At Gunsmoke, she says, environmental marketing got ahead of what farmers can actually do.
