Farmers make decisions in seasons. Plant, grow, harvest, adjust — the rhythm of agriculture is immediate, practical and tied to what this year’s weather, markets and inputs will allow. But conservation doesn’t run on a seasonal clock. Building soil health, improving water retention, restoring habitat or transitioning to new management systems often takes years before the benefits fully show up — and even longer to fine-tune what works on a specific farm.
That mismatch creates a real barrier. Adopting conservation practices can mean upfront costs, learning curves and a period where yields, labor demands or equipment needs feel uncertain. For producers already operating on tight margins and thin risk tolerance, it can feel daunting to invest today for environmental and operational returns that may take years to materialize. As a result, even practices with clear long-term benefits can see slow uptake.
That’s where innovative financing comes in. Smart financial tools can help bridge the gap between seasonal realities and long-term conservation outcomes. It can help reduce risk, smooth cash flow and reward farmers and farm-serving organizations for stewardship as benefits develop over time.
In the Midwest, the Environmental Defense Fund, a Walton Family Foundation grantee, has developed a new tool to help lenders incentivize farmers to adopt nature-based solutions at scale.
EDF has launched a sustainability-linked loan with CoBank, the largest member of the Farm Credit System, which provides nearly half of all U.S. agricultural credit. Together, the pair piloted a loan to Heartland Co-op that reduces interest rates if the co-op meets specific environmental targets, including greater adoption of nature-based solutions such as cover crops and saturated buffers and increased farmer engagement.
For the co-op, which buys grain and sells agronomic inputs like seeds, fertilizers and other supplies to between 6,000-7,000 farmers a year, even a small interest rate reduction can translate into major savings and a powerful incentive to deliver on sustainability goals.
Ruth McCabe leads the co-op’s conservation agronomy program, which puts boots on the ground to support farmers as they adopt nature-based solutions like cover cropping and buffer strips.
As farms in the Midwest continue to consolidate and farmers are increasingly encouraged to grow just a handful of commodity crops, production systems have emerged that are efficient, but also "leaky," McCabe says. “There are landowners who don't understand that their land is slowly but surely losing its productive capability. You also have a crop insurance system that is set up to incentivize short-term profits over long-term sustainability.” The result is what she calls a “race to the bottom” as soil and water quality continue to degrade.
Nature-based solutions like cover cropping are one of our best tools to counter soil and water degradation. Making it easier for farmers to adopt these practices can restore organic matter, prevent erosion and capture excess nutrients from flowing downstream.
Bridging the gap between sustainable practice adoption and farm economics is a long game for McCabe and her team. But gradually, change is happening.
In the last two years, McCabe says the savings produced by the loan have enabled her to expand her team of conservation agronomists to five people, resulting in the planting of 160,000 acres of cover crops. Additionally, her team has helped farmers install around 90 modified drainage systems called “saturated buffers” that divert nutrient-rich water into buffer strips along field edges rather than directly into the water supply.
Craig Pfantz is an Iowa corn and soybean farmer who has been utilizing conservation techniques on his farm for decades, particularly no-till. He also uses cover crops, like oats and cereal rye, to prevent erosion. But according to Pfantz, cereal rye is difficult to manage in the spring, and oats die with the cold weather. He wanted to find an alternative cover crop to cereal rye that could still withstand the Iowa winters.
After meeting McCabe at a local conference, he learned about winter camelina, a rapid-growing, hardy winter annual that could serve as an alternative cover crop to cereal rye ahead of his corn and soybeans.
With support from McCabe, Pfantz also applied and was accepted into the highly competitive USDA Environmental Quality Incentives Program, which provides technical and financial assistance to agricultural producers. As a result of the additional funding, Pfantz now has more than 80% of his land in cover crops and was also able to purchase new farm equipment.
“Ruth has amazing knowledge as far as cover crops,” says Pfantz. “She's a very, very intelligent person. And she tends to be on the cutting edge of what's happening out there. It’s always good to have somebody in your corner.”
Sustainability-linked loans like the one to Heartland Co-op are working to ensure more experts like McCabe can share practices that work, and more farmers can think long-term about how nature-based solutions can positively impact both their bottom line and water and soil health.
“The sustainability-linked loan helped us by doubling our capacity, doubling our output,” says McCabe. “At the end of the day, that's what matters. The goal of our team is to get physical practices in the ground. By doubling our capacity and our output, we're helping more farmers and having a greater impact on the environment.”
