Advancing Agroforestry in the Midwest: Hudson Demonstration Farm

CLICK TO READ ARTICLE'S KEY POINTS
  • Agroforestry, which involves integrating trees into agriculture, is a vital solution to climate change. Trees’ deep roots help manage water, sequester carbon, and mitigate the impacts of extreme weather, making them powerful allies in adapting to and mitigating climate change.
  • Demonstration farms play a crucial role in educating farmers and the public about agroforestry. They serve as practical examples, helping people understand how agroforestry works and learn all the benefits of regenerative farming.
  • The are several barriers to agroforestry adoption, including land access, upfront investments, and a lack of experienced practitioners. Addressing these obstacles is essential to encourage more farmers to embrace agroforestry practices.
  • Policy support, particularly through USDA programs and the Farm Bill, is essential for scaling up agroforestry adoption. We need policy changes that recognize agroforestry’s role in addressing climate change and offer financial incentives for its implementation.
  • Despite the challenges posed by climate change, agroforestry is a transformative practice that can positively impact biodiversity, habitat restoration, and rural communities, offering a brighter and more stable future for agriculture and the environment.

Most people have no idea what agroforestry is. And they especially don’t know what it looks like. Displaying agroforestry on demonstration farms allows people to understand how trees fit into farm landscapes.

As the Director of Demonstration Farms at the Savanna Institute, a nonprofit organization working to lay the groundwork for widespread agroforestry in the Midwest, I help people better understand what agroforestry is, as well as the multiple benefits it can provide to farmers. Demonstration farms can serve as a blueprint for how the U.S. Department of Agriculture’s programs and policy initiatives, like the 2023 Farm Bill, could support the expansion of agroforestry plantings.

Agroforestry 101

Agroforestry has a lot of definitions, but simply put, it’s the integration of trees into agriculture. By this definition, agroforestry has been practiced for thousands of years, and in thousands of different ways, across the world. A few key practices are especially promising for the Midwestern United States, such as alley cropping (rows of trees growing within rows of crops) and windbreaks (rows of trees planted along the edges of fields to reduce wind, pesticide drift and soil erosion).

So much of our country’s landscape now is foreign to what it looked like 30 years ago, 50 years ago, 100 years ago, and 300 years ago. All the amazing soil that we have here in the heartland is because of the prairies and savannas that were here. This history is extremely important, because while ‘agroforestry’ can be seen as a set of USDA practices, it’s way more than that. It’s generations of people that have been working with trees up to the present day. So, agroforestry is not only directly related to what happened in the past, but it directly informs what will happen in the future.

Agroforestry’s Role in Preparing for Climate Change

As we’re entering this time of uncertain weather patterns, farmers sometimes have no rain at all. Other times, an incredible amount of water comes onto farm landscapes all at once. Trees can play an important role in navigating this challenge. The amazing thing about trees is they have deep root systems that allow water to spread out and sink in. The perennial roots of tree crops allow them to mitigate the impacts of extreme weather while also sequestering greenhouse gases and reducing climate change directly.

Because of the powerful role that trees can play on farm landscapes, agroforestry has everything to do with climate change. Trees are some of our most powerful allies we have when it comes to adapting and mitigating a changing climate. There’s nothing more efficient than a tree when it comes to storing carbon at deep levels of soil where we need to hold it in place. And what makes trees even more exciting is they can be productive. We can put trees on landscapes in a way that is doing something for climate change, but also adding value to farmlands, either through conservation or through the production of new crops.

Drought and Planning

I have seen first-hand the impacts a changing climate is already having on farmers. Through my work at the Savanna Institute, I manage the Hudson Demonstration Farm, a privately owned, 120-acre farm in central Illinois that serves as an agroforestry demonstration site through an innovative 50-year lease agreement with the landowner. Agroforestry is being established on all of the 120 acres, in combination with corn, soybeans, and other common Midwestern crops. In 2023, a severe drought created challenges for our agroforestry work, as well as for the alley crop farmer’s soybean production. 

Even though farms in Central Illinois are seeing the driest soil we’ve had since the eighties, the trees we planted here are doing just fine, and even trees that were planted as recently as last year seem to be doing reasonably well thanks to deeper roots that can access moisture farther down in the soil. The crops that are struggling most with the drought are annual crops, like the corn and soybeans that are grown across much of Illinois and the Midwest. However, growing trees close to these annual crops can actually help them access water too, by drawing up moisture higher in the soil profile where shorter crop roots can access it. 

While this drought has led to challenges, it has also provided an opportunity to demonstrate how to farm in an increasingly chaotic climate. The future of agriculture is happening right now on these demonstration farms. As the weather gets more extreme, farmers will be forced to do things differently. 

On-Farm Education

For agroforestry to gain broader acceptance, it is important for it to be highly visible. Demonstration farms can play a powerful role in bringing people out to learn more about agroforestry. 

The Savanna Institute utilizes Hudson Farm, along with its broader network of demonstration farms throughout the Midwest, to conduct education and outreach for greater agroforestry adoption. This includes field days, private tours, research, an agroforestry apprenticeship program, and a new video series about the farms.

This education is very important, because agroforestry requires the thoughtful management of multiple systems at once, such as tree crops in combination with grains, vegetables, or livestock. This offers the potential for “overyielding” – achieving productivity above 100% due to multiple crops in the same space – but it also increases the number of things that can go wrong. Our demonstration farms help us find ways to co-exist, while also providing opportunities to document and learn from our mistakes, so others don’t make the same mistakes again. 

One of the reasons why I’m drawn to this work is because we are showing that the corn and soybean production with large tractors guided by GPS and increasingly advanced technology can exist alongside the use of trees. The future of agriculture is to do both. Both of these things CAN happen at the same time. 

Costs and Barriers

Why isn’t agroforestry more common in the Midwest? A number of significant barriers stand in the way. Land access for aspiring agroforesters, either through land ownership or a favorable long-term lease, remains out of reach for many. Because tree crops usually require significant up-front capital and labor investment with no immediate payback, providing financial mechanisms to fund agroforestry establishment is a primary need. A shortage of nursery stock for preferred agroforestry crops, as well as a lack of farmers with sufficient agroforestry management experience, also represent limiting factors. 

For example, if a farmer is planting a chestnut tree, that tree is not going to produce its first chestnuts for around five years, and they’re not going to come into full production until around their twelfth year. This means that farmers are required to make a significant investment of time, labor, and money before those trees start to produce, which can be really hard when operating farms on tight margins. In Midwest agriculture, we’re usually focused on short-term economics instead of long-term economics, and that can be a barrier for some farmers.

Another barrier is that there simply are not a lot of people doing agroforestry. A person might be the only one in their community that’s planting tree crops or doing agroforestry on their farm, and that can get really lonely after a while. Hopefully as we spread the word about agroforestry, this will become less of a barrier for agroforestry adopters. 

USDA Support for Agroforestry

While some of these barriers can be addressed by organizations like the Savanna Institute, others require innovation by policymakers or financial institutions. The U.S. Department of Agriculture (USDA) can be a powerful change agent in scaling up widespread implementation of agroforestry, and a number of USDA programs are already supporting its adoption. Through the Natural Resources Conservation Service (NRCS), landowners can access cost share funding for the cost of planting trees, as well as the loss of income from taking land out of annual production. 

Indeed, at the Hudson Demonstration Farm, the USDA helped pay for every tree that was planted. At Hudson, the NRCS’ Conservation Reserve Program (CRP) supports the establishment and maintenance of the windbreak and pollinator plantings while the Regional Conservation Partnership Program (RCPP) supports three different types of alley cropping. The Environmental Quality Incentives Program (EQIP) can also help pay for costs associated with Agroforestry establishment. EQIP is a particularly powerful program for people that may not have commodity crop land, including specialty crop growers or livestock producers who want to establish agroforestry.

Another USDA effort, the Partnership for Climate Smart Commodities program, is pulling together people working in agroforestry into regional hubs that allow us to scale agroforestry where they are located and deploy it throughout the United States. Led by The Nature Conservancy in collaboration with multiple partners, this five-year grant establishes six regional hubs in the eastern US and Hawaii. Agroforestry currently represents less than 2% of U.S. agriculture. This project aims to create 30,000 acres of new agroforestry plantings over the next five years.

In 2023, Congress has the opportunity to expand the USDA’s support for agroforestry through the Farm Bill, legislation that touches the life of every single person in the US, whether we know it or not. When it comes to agroforestry, there is a major opportunity to put in place a transformative Farm Bill, providing opportunities to tweak some existing programs to make them more friendly to agroforestry, while also providing additional funding for agroforestry research, technical assistance, and adoption. It is vital that we let policy makers know that agroforestry is important to us, that it is a climate change solution, that it is an economic opportunity, and that historic investment will help accelerate that adoption even faster.

Returning to Agroforestry

Despite dealing with the consequences of climate collapse on a daily basis, I am still hopeful about the future. As a parent, I sometimes feel that having children and planting trees is part of the same work: fostering a better, brighter, more stable future. A few years back, I was out working on an agroforestry farm and heard a bobwhite quail call from the windbreak. I started weeping, right there in the field, because I hadn’t heard that sound since I was a child. Through planting trees, that farm had built a habitat for a bird that no longer existed in the area and they came back.  Being able to watch the land change, regenerate, and diversify thanks to agroforestry fills me with the same emotions as watching my children grow. 

I think that trees have the opportunity to bring people back to the land, to farms, to their communities and rural areas, and to places where they feel like they can be hopeful and that they can build their lives around that. And while planting a tree is simple, it’s the first step in that transformation.

Soil Health Success: Herriman Farm Highlights Economic & Environmental Benefits of Soil Health Management

Adapted from American Farmland Trusts’ Herriman Farms Soil Health Case Study.

CLICK TO READ ARTICLE'S KEY POINTS
  • After facing setbacks from a flood and poor crop yields, Scotty Herriman who farms 2,000 acres in Oklahoma, learned about the benefits of soil health practices and received support through USDA’s NRCS to transition away from conventional methods.
  • The soil health methods he implemented, including no-till, cover crops, and enhanced nutrient management, led to increased yields, reduced erosion, and lowered greenhouse gas emissions:
  • A partial budget analysis showed that soil health practices increased Scotty’s net income by $4 per acre annually, with a 7% ROI. He also experienced yield increases, boosting soybean yield by 5 bushels per acre and corn yield by 40 bushels per acre.
  • Various programs, like EQIP and CIG, support farmers in adopting soil health practices, improving financial and environmental outcomes. Federal Farm Bill programs and initiatives like the Partnership for Climate-Smart Commodities can further promote these practices.
  • Scotty’s experience emphasizes the learning curve and importance of sharing success stories to encourage informed conservation decisions in agriculture.

Scotty Herriman farms 2,000 acres near South Coffeyville, Oklahoma, with his wife, Jo. They grow corn and soybeans, and occasionally grain sorghum (milo) and wheat. After a historic flood in 2007 resulted in only 13 profitable acres, followed by a poor crop yield in 2008, it became clear to Scotty that he needed to change the way he farms his land.

Scotty heard about other farmers who had had success with practices like no-till farming  – which is planting agricultural crops without any plowing or tillage. A visit to his local USDA Natural Resources Conservation Service (NRCS) field office in 2010 finally changed Scotty’s mind. He learned he could use assistance through the Environmental Quality Incentives Program (EQIP) to switch to no-till. Just like that, decades of conventional farming went out the window. “We switched overnight,” Scotty said.

In recent years, more and more farmers in the U.S. have been adopting farming practices that provide multiple benefits for the farmer, the environment, and our climate. These strategies go by many names – regenerative agriculture, climate-smart agriculture, conservation agriculture – but they all refer to a suite of farming practices that improve soil health. This, in turn, sustainably improves farm productivity, enhances the resilience of land to drought and flooding, and provides a number of environmental benefits, including cleaner drinking water, increased carbon storage in the soil, and reduced greenhouse gas emissions.

BENEFITS OF NO-TILL FARMING

“No-till farming protects the soil from excessive erosion, reduces soil aeration from tillage, allows organic matter to accumulate and improves the overall health of the soil. Switching can also help you reduce input costs and, thus, boost your bottom-line profits. It is part of an integrated effort to conserve the nation’s natural resources.”

—U.S. Department of Agriculture’s Natural Resources Conservation Service (USDA-NRCS)

From Adversity to Achievement: Scotty’s Experience with No-till, Cover Crops, and Enhanced Nutrient Management

In 2010 Scotty adopted no-till soybeans and reduced-tillage corn. While this has led to some increased use of herbicide, adopting no-till has saved Scotty time, reduced equipment maintenance costs, and has led to significant positive changes in his soil. For example, Scotty sees that root channels from prior year plantings run deeper into the ground, which improve soil infiltration and create a more stable and resilient soil structure. Scotty has also seen higher quality crop stands that are less stressed by drought and pests due to increased crop vigor.

With the goal of reducing herbicide use, Scotty adopted cover crops, primarily cereal rye in 2016. Cover crops are sown when a primary cash crop is not present, as an alternative to fallow, or bare soil. Cover crops have been shown to slow soil erosion, improve soil health, enhance the availability of water, smother weeds, and help control pests. They also increase the total amount of photosynthesis that takes carbon from the atmosphere, which can increase the amount of carbon added to the soil every year. While planting cover crops has led to only a slight reduction in Scotty’s herbicide use, he has observed that they leave a mulch layer an inch thick on top of his soil, which he believes has increased soil moisture retention – making his land more resilient to drought. “A couple of years ago I noticed things started to come on stronger,” Scotty says. “I won’t say we were penalized those first 2 years, but it was after that 2-year period the yields were coming on strong. Weather patterns were the same, water intake was good, so after just a little period of questions and small doubts, that 3-year window everyone talked about opened up and crops have been improving ever since.”

In 2016, Scotty also modified his nutrient management practices. He now ensures that the amount of nitrogen applied to agricultural fields by synthetic fertilizers does not exceed the amount the plants can absorb and minimizes unwanted losses by switching from dry to a split application of a liquid fertilizer blend. This reduces excess nitrogen from being released to the atmosphere in the form of nitrous oxide, a greenhouse gas 300 times more potent than carbon dioxide. It also prevents nutrient pollution in rivers and lakes, which can reduce the quality of drinking water and cause algal blooms and dead zones. While his nutrient costs increased, the modeled estimates for losses of nitrogen and phosphorus on his land dropped substantially as a result of the no-till, cover crops, and nutrient management practices Scotty employed. 

Soil Health Management Benefits Farmers, Climate, and the Environment

To better understand the financial impact implementation of these practices had on Scotty’s operation, American Farmland Trust and the Oklahoma Conservation Commission worked together to conduct partial budget analysis to analyze the marginal benefits and costs of adopting cover crops, strip-till corn, no-till soybeans, and nutrient management changes on the 350 acres of Scotty Herriman’s 2,000-acre farm where all of the practices were adopted. The analysis used a combination of published machinery and material cost estimates and farmer-provided data to estimate the cost of operations, on average, before and after soil health practice adoption. The analysis was limited to only those income and cost variables affected by the adoption of these practices. 

The results of the study highlighted the win-win nature of these solutions – they can be good for farmers, and are certainly beneficial for our climate and the environment as a whole. The analysis found that Scotty’s net income increased by $4 per acre per year after he adopted the soil health practices described earlier, for a net increase of $1,402 a year – a 7% return on investment. Scotty attributes 25% of his corn and soybean yield increases since 2010 to his adoption of soil health practices, thus accounting for a benefit of $28 per acre each year. Scotty’s average annual soybean yield has increased overall by 5 bushels an acre, and his corn yield has increased by 40 bushels an acre. Scotty says he also knows he’ll realize tangible assets of no-till during his farming career. In 2014 he saw 260-bushel dryland corn and he’s hit several years of 200+ bushel corn since switching to no-till. He entered a yield contest and won it four times in 6 years with his dryland no-till corn. This is what he shares with critics, that he implemented no-till and it works.

While Scotty’s herbicide costs have increased by $7 per acre per year, his machinery costs have decreased by $32 per acre per year since his adoption of no-till and strip-till thanks to fewer mechanical issues, less overall machinery maintenance costs, less fuel needed, and increased time savings. 

As a result of the combined soil health practices, erosion has decreased by 1 ton per acre per year, as estimated by USDA’s Nutrient Tracking Tool (NTT), worth $713 per year across the study area based on the $1.18/ton value of soil nutrients no longer running off, and Scotty’s estimated $300 a year in reduced mechanical erosion repair costs. In addition to the economic benefits Scotty has experienced, he has noticed benefits to his soil structure and biota. Scotty has observed less soil compaction, an increase in earthworm activity, and higher levels of soil organic matter. 

To estimate the water quality and climate benefits of these soil health practices, researchers used NTT and COMET-Farm tools on a 60-acre, representative field. Scotty’s use of cover crops, strip-till, no-till, and nutrient management reduced nitrogen, phosphorus, and sediment losses by 73%, 22%, and 86%, respectively, as estimated by NTT. Further, his combined soil health practices resulted in a 54% reduction in total greenhouse gas emissions as estimated by the COMET-Farm Tool, corresponding to taking 3.9 cars off the road.  While this may seem like a small number, there is enormous potential for scaling these benefits – especially considering the 396 million acres of cropland in the U.S.

Support is Available to Help Farmers Like Scotty Herriman Adopt Soil Health Management Practices

A number of federal and state programs are available to help farmers like Scotty Herriman adopt soil health practices – many of which are supported by the federal Farm Bill. To aid his transition to no-till, Scotty received support through the Environmental Quality Incentives Program (EQIP), which provides financial and technical assistance to farmers to help them integrate conservation farming practices into their lands. When Scotty planted cover crops on his land, he partnered with Oklahoma State University, the Oklahoma Conservation Commission and the NRCS Conservation Innovation Grants Program (CIG), which worked with him to study the influence cover crops had on soybean and corn productivity. Scotty also receives $5 per acre/year from the USDA Risk Management Agency Cover Crop Program to support continued implementation of cover crops. The financial assistance Scotty received from these programs was not factored into the cost-benefit analysis conducted by American Farmland Trust, indicating the benefits of soil health practices outweigh the costs even without federal assistance. 

Farm Bill agriculture programs, coupled with new efforts like the Partnership for Climate-Smart Commodities, can play a key role in scaling up adoption of these practices nationwide – not only by providing financial and technical assistance to farmers, but also supporting the research, data collection, reporting and verification necessary to continue improving our understanding of the benefits of soil health management.

Closing Thoughts

Herriman Farms has benefited from soil health practices, but Scotty recognizes the challenges that come with getting started. “It’s a learning curve. Learning how to work in harmony with the weather, resisting the urge to break out the plow when things didn’t go exactly how I envisioned, and timing the planting windows to get the most benefit of moisture while staying ahead of weeds,” he said to emphasize the effort required to forge the right soil health management system. Scotty believes in the importance of sharing his story to help others make informed decisions about conservation practices. He celebrates his healthy soil and looks forward to the lasting benefits of his hard work.
