Mollie Engelhardt’s farm looks messy. 

Every inch of Sow a Heart Farm in Fillmore, Calif., is growing one of more than 300 types of plants. In between the rows of fruit trees, Engelhardt has got organic peppers, garlic, broccoli, and cauliflower, all covered with a thin layer of grass or clover. On a recently harvested plot, chickens and sheep are eating the scraps, churning the soil so it’ll be ready to plant again.

“The neighbors' farms are perfect rows of the exact same thing with bare soil underneath. The trees are managed by spraying herbicides,” Engelhardt says. “You can see that every inch of my farm is covered.”

The chaos is all by design.

This farm is an experiment in regenerative agriculture, intended to grow healthier food at the same time as tackling climate change.

This is still far from the norm in farming – less than 1% of American farmland uses regenerative ag techniques. But this year the Farm Bill, a major piece of U.S. agriculture legislation, is up for renewal, and regenerative agriculture practitioners hope that could change.

“Folks in D.C. are already starting to think about what they want to see changed in the Farm Bill,” says regenerative agriculture expert Arohi Sharma with the Natural Resources Defense Council. “The fact that we're talking about soil health, the fact that we're having hearings on regenerative agriculture, is a huge step in the right direction.”

The world’s oldest carbon capture technology

The term regenerative agriculture refers to a handful of practices that create healthy soil. The most visible is the wild mix of plants in Englehardt’s lush, chaotic plots. She carefully picks what grows where so the plants work together to thrive.

“Fennel is actually an insectary. So the fennel is keeping the bugs off of the kale without spraying any pesticides or anything,” she says.

She grew corn next to young avocado trees a few years ago, so the tall stalks could provide shade during a hot autumn. When she harvested the corn, she planted fava beans, since they’re good at restoring nitrogen in the soil 

Englehardt’s also keeping the ground covered and hand-harvesting her crops. All of that makes the soil healthier.

“By diversifying what you grow, you're providing different kinds of nutrients to the soil. It’s like diversifying our human diets,” Sharma says.

Better dirt means more plants photosynthesizing, sucking carbon out of the atmosphere, pulling it into their roots, and shoving it into the ground. That makes it a useful climate change tool. Sharma estimates if every farm in the U.S. operated this way, it would remove as much carbon as shuttering 64 coal plants.

Englehardt says the climate benefits don’t stop with carbon capture.

“Not only are we sequestering carbon, I'm recharging the aquifer far more than the neighbor is,” she says. “And the water filtering through my soil is clean, has no glyphosates, has no Roundup, it has none of that.”

In drought-ridden Southern California, Engelhardt’s soil is better at soaking up whatever water it gets. After the giant storms last month, her dirt roads were flooded but her plots were just soft and damp.

The future of farming?

Making regenerative agriculture a mainstream practice has been an uphill battle.

“It's an overhaul of our food and agricultural system, which is rooted so deeply in our commodities, in our subsidies, in our insurance policies, in our financial system,” says Jesse Smith with the White Buffalo Land Trust just north of Santa Barbara, which does trainings and courses on regenerative agriculture. 

Sharma agrees: “From the 1970s onwards, decades of agricultural policy have prioritized unsustainable farming practices over regenerative ones,” she says.

Take the way crop insurance is structured. Right now, a corn farmer who had a bad year can claim the loss on that crop, and the government helps them out. A farmer growing corn and soy would write two claims. But what if you, like Englehardt, grow 300 different crops?

“It's a lot harder for them to write an insurance policy or claim insurance rewards because of just the number of crops that they have to keep track of,” Sharma says.

Plus, farmers using these techniques need to pay for more labor, because mechanical harvesting harms the soil.

Englehardt says she grows more food per acre than the conventional farms next door, but four years in she still hasn’t turned a profit.

“You can't expect to be making money right away in any business. The guy down the street? The first four years, he had lemons and avocados planted, he certainly wasn't making money either,” she says.

But convincing a farmer who’s currently turning a profit to change their practices even though they won’t make money for a few years is a tough sell. 

Still, Smith says he’s seen an increase in people coming to the farm for their regenerative agriculture trainings and courses.

“We’ve had cowboys from the Midwest, young up-and-coming farmers from the inner cities, to grandparents looking to figure out what to do with their property, to people who don't have land looking to get into agriculture, to people who are in computer programming, figuring out how to put their skills in service of natural ecosystems,” he says. ”It’s such a broad range of people.”

The farms trying it so far are small, Smith says, not like the thousands of acres devoted to Smuckers jam or Cuties mandarin oranges.

While some farmers wait on the government to make regenerative agriculture more profitable, Smith says it’s catching on with people like Englehardt prioritizing their positive impact.

“There is a misconception that this is a fringe niche movement. And it's not. People are transitioning large, large swaths of land,” Smith says. “It may not be a windfall, but in the hearts and minds of people who are watching, what is being demonstrated is greatly impactful and will set the stage for the coming decades of agricultural production in this country.”

A meeting on sustainable fishing in Seattle could inspire greater protections for Washington state's waters in Olympia. The State Innovation Exchange held the "Sustainable Aquaculture and Working Waterfronts" convention with lawmakers from 13 states.

Emma Newton, senior associate with agriculture and food systems program for the State Innovation Exchange, said big corporations dominate agriculture and farming, but large-scale, industrial fish farming isn't in the United States - yet.

"However, we are seeing increased interest in putting these large-scale, essentially factory farms of the ocean in our waters, and they're a direct threat to our ocean ecosystems, our local fishers and the native fish populations," she said.

Newton added the convention focused on how policymakers can protect sustainable and local fishing economies and tribal food sovereignty.

Rep. Mia Gregerson, D-SeaTac, attended the convention and said the state banned some fish farming practices after tens of thousands of non-native Atlantic salmon escaped a fish pen in 2017. Gregerson added the state needs to go further to protect the region from industrial fish farming.

"We're only able to control the policy for about three miles off the shore, and so it's going to be really important then, right, to make sure that we have a state coastal zone management plan that prohibits the same type of farming beyond just state waters," she said.

Newton added events like the one in Seattle are important because policymakers are able to connect with communities and the people working on these issues, making them more effective in their decision making.

"They're able to know that they don't have to go to the large corporations or the lobbyists for the information they need. They can go directly to the community. They're building relationships that circumnavigate the traditional way that policy is being made," Newton said.

Farmers in Iowa are studying interactions between crops, water usage, carbon and nitrogen storage, and how those factors combine to affect longterm soil biodiversity. It's part of a seven-state project in the Midwest.

Researchers are looking at the effects of crop combinations on soil and moisture across the Corn Belt.

Iowa State University Agronomy Professor Sotirious Archontoulis is running one research site in the five-year, $16 million project.

He's monitoring how crop management, carbon and nitrogen content affect soil moisture - and will try to predict the impact on the viability of future crops.

"We have the same setup in many different environments to capture different organic matter, soil hydrology conditions," said Archontoulis, "so we get a better understanding of the complexities in the agronomic system."

Archontoulis said scientists can also study greenhouse gas emissions from the soil.

He said these ultimately affect its health and can have an impact on large ag operation waste runoff, which is known to pollute nearby ground and surface water. The research is gearing up now.

Based on the computer model's findings, Archontoulis said researchers can make recommendations to farmers based on - for example - how much nitrogen the soil is losing in certain places, and how they can adjust planting schedules as a result.

"We can say, 'This cropping system with this management practice typically loses that amount of nitrogen,'" said Archontoulis. "'However, the other combination of cropping system could reduce nitrogen loss and improve productivity by X%, so this is a better strategy to move forward.'"

Archontoulis said the research begins across the Midwest this summer.

Washington state has allocated nearly $1.5 million in grants to support local food systems and supply chains. The Washington State Department of Agriculture distributed the funds to 40 projects, supporting farmers, food and meat processors, and distributors.

Galen Van Horn, local food system and supply chain specialist with the Washington State Department of Agriculture directed distribution of the funds and said there has been consolidation in the large-scale market that small and mid-sized operations can combat.

"We've just seen a clear need for investment to support those small and mid-sized operations and make sure the infrastructure is scaled to meet their needs, and that we don't just have very, very large food system infrastructure - like processing facilities and aggregation points - that are only really scaled for very large farms and food businesses," he explained.

The seeds of the program began in 2021, when the Washington Legislature distributed federal COVID-19 recovery funds to support local food infrastructure because of the pandemic's impact on supply chains. Since 2023, the Local Food System Infrastructure Grant program has distributed $8 million in state funds.

Van Horn said the program is popular and received nearly $19 million in requests - well over what it could provide. One project selected in 2022 was the nonprofit Columbia Community Creamery, which received more than $450,000.

"They got a large grant to get the equipment necessary to receive bulk milk deliveries, and then process that into jars and have it ready to be consumed. A lot of food safety involved there," he continued.

The Washington State Department of Agriculture expects to start the next application round in the summer or fall of next year. Van Horn said the agency looks for proposals that impact the regional food system, are achievable and ask for a reasonable amount of money.
