Organization and its farmland
Whiterock Conservancy owns and manages approximately 602 acres of row crop (corn, beans, small grains) and 883 acres of pasture. In 2022, we hayed 236 acres, 35 of which were alfalfa. We also hold 10 soil health easements across 2,155 acres. We do not own this land but were gifted the conservation easements on them and so are obligated to monitor and maintain those easements in perpetuity.
We farm in Guthrie County and Greene County. Our soil health easements span Guthrie, Greene, Carroll, Audubon, and Monona Counties, all in Iowa.
Maybe. We would particularly be interested in land contiguous to the Conservancy. We are also pursuing additional soil health conservation easements across the state.
I would guess up to 90% of our farmland will still be farmed in 10 years. As we continue to monitor soil health and yields as well as consider organizational priorities, we may decide to enroll more ground in CRP or convert more acres to habitat. I expect that we will continue to farm quite a bit of ground into the future, however, given the income and opportunity to demonstrate regenerative practices.
Most of our farms have fencing of some sort, maybe 75%. Several have wells and farm buildings, as well.
Maybe. We are interested in grazing more of our ag fields and could use more fences for that, but they likely wouldn’t be permanent, same with shelters for livestock. There are also some spaces we could graze if we had access to water, but we don’t currently have plans to drill any additional wells or install more water lines. Our focus right now is maintaining what we already have.
Yes, we give tours of our fields and facilities to discuss regenerative ag concepts and sometimes put out content on social media, on our blog, and in our newsletter. We also offer support to soil health easement grantors and operators regarding the practices mandated in the easement, such as no-till and cover crops.
Our farm revenue helps cover our nonprofit’s operational expenses, in conjunction with revenue from recreation and donations. We also reinvest in the upkeep of our farms and equipment, as well as experimentation with different BMPs.
Farmland management decision-making, staffing, and policies
I think I’d say two full-time equivalents. Matt, Tyler, and I have additional duties but we also have a part-time staff member who helps quite a bit with the farm program, so I think all of our farm time together would amount to two full-time folks year-round.
We have some organizational policies around expenditures and chain of command, but otherwise I’d say we’re guided more by principles than policies, like “the conservation and improvement of soil health.” Unless you’re asking about state and federal policies.
Yes. We proudly support local producers through our lease program, some of whom market livestock and meat locally. We don’t have much beyond that just yet—our vegetable garden tenant mostly grows recreationally and our vermicompost tenant is still growing their operation—but we hope to foster more local food production in the future, perhaps through additional leases or a farm incubation program.
Relationship with Farmers and Conservation
We have 4 row crop leases, 5 pasture leases, and 5 facility leases, for a total of 14 agricultural leases. We also have a set of hunting leases and CRP leases, which we have not included in these totals.
Not our row crop or pasture – we include a termination letter with those during lease signing to ensure that Whiterock has the flexibility to change lease arrangements and/or our program annually. Our facility leases currently are automatically renewed by a certain date unless either party suggests changes, however, as we wanted to be sure that our tenants knew the particulars of their lease arrangements in time to plan their operations. We may change that going forward, again in the interest of organizational flexibility.
Yes, we share the cost of cover crops with our row crop tenants and we manage erosion control structures and other BMPs on our farms.
No, not at this time.
Yes. We work with tenants to test new conservation approaches and have custom farming arrangements around some of our experiments, such as our small grains rotation. We are also open to experimentation from our easement land operators, provided their goals align with that of the easement.
We have a lot of CRP ground around our farms, including edge-of-field buffers and filter strips. Whiterock maintains these, but our tenants and operators do need to work around them.
No, not at this time.
We don’t have any formal activities but do try to meet in-person several times throughout the year, outside of the official lease negotiation and signing period, to check in.
Monitoring and Information systems
We use GIS for recordkeeping, planning, and mapmaking. We have a server and cloud-based folders for recordkeeping, as well, and file sharing. AgLeader and John Deere systems are also used on our farms to capture in-field activities.
[Not Answered]
Yes, though not as much as we’d like. We pay an outfit to take samples every few years on the ground they custom farm to assess OM and chemical properties. I believe they use the same lab each time. Our row crop tenants are responsible for soil testing on their ground, as well as sharing results. We don’t prescribe any particular test or frequency. We do test our easement ground, assessing aggregate stability twice a year and running a Haney test once a year; these go to the same lab each time. Whiterock pays for testing, in this case.
No, other than anecdotal observations.
Kind of. We watch for gullying, alluvial fans, etc., but we don’t have a monitoring program/protocol and we don’t measure erosion in a quantifiable way.
Yes, we participate in the Iowa Soybean Association water testing program, contributing samples from our streams, the Middle Raccoon, and several of our tile lines as well as a wetland.
Yes, we conduct a 5yr bird survey. Otherwise, we rely on anecdotal observations.
Yes, soil testing results.
Just field scouting, yields, and observed cover crop performance.
Bigger Picture Questions
From the past three years, we are most proud of our small grains rotations which incorporate multispecies cover crops, the infrastructure improvements and additions we have made to increase our capacity for rotational grazing, and our relationships with our tenants and other partners which allow us to experiment with things like flash grazing and prescribed grazing for invasive species mitigation.
One of our biggest challenges is the strain on our resources, whether it’s staff time, equipment hours and wear and tear, or cash for inputs and maintenance. Relatedly, our second challenge is weighing the costs and benefits, keeping in mind budget constraints and our relationships with our lessees and producers. To make things even more complicated, we invite the public onto our land for education and recreation, so are also thinking about visibility and educational opportunities as we make decisions, and sometimes have to shift things around on the landscape to accommodate visitor traffic—some of our trails shift throughout the season as cattle are rotated to different paddocks, for example.
Over the next five years, we will continue to evaluate and reconfigure our farmland according to our organizational needs and goals. I imagine we will enroll more ground in CRP, taking any farms with poor soil, low yields, and steep slopes—or those adjacent to habitat that we would like to expand—out of production. We would also like to custom grow more small grains and continue to experiment with different cover crop mixes within the rotation. We hope to build a more robust soil testing program, perhaps dovetailing our assessments at Whiterock with those we undertake for the easements we hold. We will continue to improve our rotational grazing infrastructure and pastures and would like to graze more cover crops. Finally, we want to formalize some of our experiments into research studies that we can more easily monitor and share.

Tyler Bruck, Land Programs Manager
Focus on Agricultural Stewardship: Agriculture was part of Whiterock Conservancy’s mission from the founding, in part because of the legacy of the Garst family, which founded the Whiterock Conservancy and which had long been innovative in their farmland stewardship. Some of the land that the Garst family donated to the Whiterock Conservancy, for example, had been in no-till since the 1980s and had erosion control structures. In addition, the Whiterock Conservancy was originally founded as a 501 c 3 non-profit with the mission of supporting three organizations – Iowa Natural Heritage Foundation, Iowa DNR, and the Leopold Center for Sustainable Agriculture at Iowa State University. The work with the Leopold Center had some influence on Whiterock’s direction as did the fact that a good number of the initial board of directors had expertise in sustainable agriculture as well.
Management Policy: The organization tends to be guided more by soil health principles rather than formal, abstract policies. The staff feels quite good about how they are applying some of the principles but also recognize where they are falling short of their ideals. In the case of maximizing biodiversity, for example, they’ve not been able to use the diversity of cover crops they would like to. They also have been permitting the use of conventional agricultural chemicals.
“The really cool thing is that we do have the flexibility to try out new things and experiment a little bit,” says Carissa Shoemaker. “And so for me, it’s fun to be flexible and to be able to ultimately, show the area producers what maybe they could be doing.”
When it comes to deciding what to farm and what not to farm, they have a policy of so-called “farm the best, leave the rest”. In practice, this means only farming land that has the best soils and farming conditions, and putting other land (approximately 1,000 acres) into CRP. They continue to carefully assess how much land they can responsibly farm while also paying attention to yield data and the input of staff and farmers about which areas are good to farm and which land isn’t best used for agriculture. In general, they want to have more diversified production going forward, like flash grazing (grazing of cover crops), small grains that allow more diverse crop plantings, and adding alfalfa to the rotations.
Whiterock Conservancy staff has the desire to use data to drive more of their decision-making around farming practices and to gather clear lessons from trials, but they find that they often do not have the capacity bandwidth needed to collect the data and analyze it. Going forward, Whiterock Conservancy wants to request more farmer data, including yield data and spray data, and use all of that data to do more holistic analyses of their different farm properties. They do use GIS analysis to some degree, by layering different types of data available online (like soil types and the Iowa Corn Suitability Ranking) and examining historic aerial imagery to determine cropping, fencing, and access approaches in the past. Whiterock also has the desire to use GIS as a data recording tool. GIS is already an invaluable tool for their pasture system planning as all their fences have data related to their condition in Whiterock Conservancy’s GIS system. “So when we’re planning for fencing infrastructure improvements,” says Carissa Shoemaker, “we can talk to the guys in the field and also look at the indicator symbols related to the condition of the segments making up our 5,500 acres of total fencing. That’s really powerful. It’s just a lot of data to manage. So we need people to update it.”
Whiterock would like to have more partnerships with universities and other entities who would be able to do the data collection, entry, and analysis. As part of the statewide water quality assessment program, Whiterock Conservancy staff collect water quality samples from a number of different creeks, including the Middle Raccoon River, and another entity picks up the samples and transports them to a facility for actual testing.
Whiterock also tests some of their drain tile lines, and the data that has been gathered does show a spike in nitrates around the time Whiterock fields are having fertilizer applied. The spike, however, is not as high as seen in other drain tile testing on other properties. Nevertheless, Whiterock recognizes that they could benefit from tightening up their nutrient management.
The organization even leverages historical data to inform how to best manage land. There are opportunities to improve, specifically as it relates to grazing activities and how they impact natural habitat. This includes mapping via GIS the location of vital infrastructure, wildlife corridors, and grazing paddocks.
Farmer Relationships: The Whitehouse Conservancy prioritizes partnerships with farmers, especially on data collection efforts. Where gaps exist in data collection, they will work with local universities and industry associations to help address the research gap. This community engagement strategy is important when trying to build a more holistic picture of land use and management.
To have the capacity to have closer working relationships with its farmers, Whiterock Conservancy hired Tyler Bruck as the land program manager. It is Carissa’s impression that this is working well. “I’ve seen it matter to producers that Tyler can just go out and talk to them and meet with them,” says Carissa. “I think that Tyler’s really good at relationship building, because he’s also reliable. If you call Tyler, he’ll answer and he’ll show up early to your meetings. He’ll get out in the field with these guys which I think they also respect. I’m really glad that Tyler’s position now exists, because that makes us more available and more flexible in working with producers.”
Tyler says that building and keeping good relationships with farmers is important. “I’ve learned you need to be willing to stick your neck out there a little bit, too,” says Tyler Bruck. “Looking at it from a business standpoint is important, but I think if you just keep the people in mind, that’ll kind of carry you through. There’s difficult parts that you have to do from day to day, whether you have to tell someone you’re grazing too short or kick them over to the next paddock. But I think in the end if we’re on the same page, and they know that you’re going to be there for them, that’s what is really important.”
Having Tyler’s capacity also allows Whiterock to start planning conversations earlier, something Whiterock hadn’t been consistent with in the past. Delays in signing leases, for example, could put producers in a tight spot as producers need to plan far out in advance for inputs. Whiterock is working to do better in the timeliness of its planning and leasing.
Even with access to staff who have helped manage the farmland for decades, there have been times when Carissa and Tyler have not known the history of past arrangements or verbal agreements that might have been made, and this has hurt them in farmers relationships. “I think that sometimes hurts our credibility,” says Carissa, “or rubs them the wrong way.” Yet, Carissa and Tyler, have also brought fresh ideas and perspectives, which has been positive for the organization.
“What Tyler and I have noticed is there’s just so much history with these producers,” says Shoemaker. “We’re fortunate to have long-standing producers who have been farming this land for decades, and they’ve seen so much staff turnover here. We try to walk through their leases with them and say this is what we’ve changed and this is what it says. But I think sometimes they might just make assumptions or remember what they’ve done in the past. It might not occur to them, even though we did write it in the lease, that they have to ask permission. They’re just doing what they do every year.”
Leasing Structure: In addition to more conventional cash rent leases. Whiterock Conservancy is implementing variable/flex rents on 322 acres of their land. Under the flex lease, the farmer pays a low base rate in early spring as a sort of downpayment. Then, at the end of the year, an average price is calculated for that year by calling the local coop and asking for closing price on a particular day of the month across four months. That average price is then multiplied by the number of acres being farmed under the lease and then by the yield. Under the flex lease, Whiterock is entitled to a percentage (33% for corn and 46% for soybeans) of that calculated value with a minimum required rent amount set as well as a capped maximum. Under this system, Whiterock and the producer share in the risk and reward of the farming that year. Once the total rent is determined, the producer pays the difference between the downpayment they already paid and the total rent due. In 2022, Whiterock netted ~$345/acre on soybeans under this system, even as the average land rent in the area was $250-$300.
On Farm Conservation Practices: Rye is used as a cover crop on almost 600 acres of Whiterock Conservancy land each fall. Recognizing that required a large amount of seed, Whiterock Conservancy decided to grow its own cover crop seed supply. So the organization uses custom farming arrangements with other farmers to plant some of the Conservancy’s own acreage with rye, harvest the rye seed the following summer (which will then be used as cover crop that fall), and then plant new diverse cover crop mix on fields from which the rye had been harvested. That diverse crop mix is then grazed in the fall, and some straw is harvested and sold as well. Production oats are also grown at Whiterock and are usually rotated between different fields to promote soil health. In fact, on one field that is incredibly sandy in pockets, the oats still do better than any other option. In 2023, seven acres were allocated for oat production. Twelve acres were planted with rye seed (using a new variety) in the fall of 2022 for seed production. Oats are then sold to the company Iowa Cover Crop, which is not too far from Whiterock Conservancy. Rye seed not used as cover crop on Conservancy land would also be sold or would be stored.
Whiterock Conservancy usually decides to plant rye and oats for seed production on land that needs rehabilitation or that doesn’t yield well for normal row crop production. Fields that receive the rye or oat production cycle plus the diverse cover crop mix that is grazed off are usually then returned to corn and beans as part of a three-year rotation. While there is no data collected yet, Whiterock Conservancy feels confident that between the fibrous roots of oats and rye plus the impact of diverse crops and grazing there is a positive impact on water infiltration and organic matter.
“We’re hoping to experiment with more cover crop varieties for seed production,” says Shoemaker. “We’ve been talking to Iowa Cover Crop about contract growing buckwheat, which we tried as a cover crop last year, and it did really well. Another thing we’ve done in the past is we’ve grown a nurse crop of clover or alfalfa and then oats over it so that we have like a whole succession that rehabilitates the land. And I think we’re going to do that again after our alfalfa gets a little bit older and doesn’t yield as well. We want to make sure that there’s a market for what we grow, and we need to make sure our equipment is compatible because those were the farmer’s first questions about the buckwheat: how do you harvest it and is it the same equipment that you already have?”
Custom Farming: Whiterock Conservancy uses custom farming (hiring a farmer to carry out a particular task) on about 280 of its 602 row crop acres. Custom farming enables the organization, which is spread thin, to outsource some of the labor and to reduce the number of pieces of expensive equipment it must purchase. Reinvesting farmer profits in farm equipment makes sense for private farm business, but for a nonprofit like Whiterock, there are many pressing needs for the use of the revenue from farming. So while Whiterock has some of its own equipment for drilling seed and spraying, it prefers to use local producers (and their well-maintained equipment) for other tasks.
Grazing: Whiterock Conservancy has four rotational grazers, with one of them grazing around 400 acres, by far the largest production operation. The grazers usually have a flat lease rate per acre. Grazers are required to carry out rotational grazing, and Whiterock staff monitor to make sure that is happening frequently enough. While some flash grazing of cover crops is happening already, Whiterock staff would like to increase grazing of cover crops and even row crops in the future, although the scheduling window in the spring can be very tight.
There are a few pastures that don’t have smaller paddocks that would allow daily moves. While Whiterock hopes to get NRCS funding to be able to subdivide those pastures in the future, in the meantime the producers are expected to move cattle in and out throughout the season as part of their greater rotational system. Because of the circumstances of some of the producers, it is not always feasible for them to move the cattle as frequently as Whiterock would like. Whiterock is also trying to get better about assessing the forage quality of their pastures and to get on a rotation again interseeding and overseeding of clover into the pastures instead of relying on fertilizers. What is making this especially attractive is that there is great cost share for this approach.
Other producers in the area would also like to graze on Whiterock lands. This is a mixed blessing for Whiterock as it is good to have interest but it is challenging when not everyone who is interested can be accommodated.
There is one bison grazing operation on Whiterock land. The bison are rotated among pastures but far less frequently than the cattle. This is in part because the bison don’t care to be handled, and Whiterock staff are not eager to handle them, especially in tight spaces. The paddocks they use are six to ten acres each. There has been experimentation with seeding native species, thinking that the bison would like that. “That’s kind of been a failure,” says Shoemaker. “The natives have not come up either because of grazing pressure or because of the brome just being so aggressive.”
Chemical Management: Whiterock Conservancy has some guidelines and chemical use restrictions that are designed to prevent residual impacts within the soil. The organization also prohibits most fungicides (due to harm caused to soil health and insects) and insecticides, unless there is a really threatening problem for which there seems to be no alternative. However, the leases themselves do not currently spell out chemical use restrictions, though this is under consideration. Instead staff ask producers to get permission before they apply anything.
Finally, Whiterock Conservancy is researching alternatives for seeds treated with neonicotinoids. In addition to environmental impact, they have to be considerate of the potential impact on their partners’ operations. If they were to impose restrictions that added cost, they could explore a phased cost share mimicking that of their flex leases. Whiterock Conservancy could initially cover most of these extra costs and then decrease the proportion of support over time. This approach was used when Whiterock added stipulations requiring cover crop adoption. Cost sharing in the initial stages of the transition was successful.
Soil Health Easements: In addition to management of its own 1,721 acres of farmland, Whiterock Conservancy also holds ten soil health easements on properties owned by other people. Like other types of easements, soil health easements attach to the property’s deed and follow the land in perpetuity, allowing a landowner to place conservation restrictions on the land. And like other types of easements, they protect natural resources, water quality, and scenic views. But unlike other types of easements, the main purpose of these soil health easements is to see that soil and its health is conserved. This tool ensures that soil health is always protected, even as the land changes hands. As the holder of those kinds of easements, Whiterock Conservancy is obligated to monitor the associated land in perpetuity not just for usual conservation easement factors (prohibited development, etc.) but also for soil degradation and best management practices prescribed in the easement (erosion control structures, continuous living cover, minimizing disturbance, etc.). The landowner, no matter who owns it at any particular time, must follow certain practices and not allow other prohibited uses that would damage soil health. So, for example, tillage is not allowed unless Whiterock Conservancy gives written permission in advance. Generally, these easements are donated to Whiterock Conservancy and come with an additional financial donation from the landowner to ensure the monitoring and protection of the easement can be carried out in perpetuity.
