Going the Extra Yard

A few years ago, Liz, Matt and I attended the funeral of Barry Kusel, one of our dedicated ILF farmer partners. Barry had passed away unexpectedly right before Thanksgiving that year. Barry was always someone we could turn to when we needed a strong advocate for cover crops or no till. Attending his funeral was important. None of us knew the rest of his family but I kept thinking that Barry was always willing to go wherever we asked him to go in order to help educate others about cover crops. Since Barry was always there when we needed him, we needed to be there for his family when they needed us. I know it meant a lot to his mother and his wife that we would come from Iowa State to pay our respects.

Two people in my own life really stand out for helping me learn the lesson of going the extra yard for folks: Joe Gronstal and Steve Padgitt. They didn’t teach me so much by their words but by their actions.

Joe was an old friend of the family but I really got to know him when he invited me to spend the summer at his house on Spirit Lake years ago. I was young and sort of in between things. A summer on the lake sounded great. Joe was an “old school” guy. He had his own way of doing things around the house and he was good at getting everyone around him to do it his way. You knew you were in trouble when Joe would look at you with that twinkle in his eye and say, “Well, I was thinking maybe we should try…” That summer, I would go along with whatever he asked me to help out with. His kids still tease me about how he got me to sit in the canoe and paint the side of the dock. He thought it would be easier. Trust me, it wasn’t easier.

What really stands out to me from that summer was how generous Joe was with his time and resources. He would drive hours one-way to visit a sick friend or do a favor for a friend. He was always looking out for his neighbors. He would point out to me the importance of being there in person for other people. My parents also did that in their lives but Joe used to go to such lengths to be there for his friends and neighbors that it really impacted me.Steve Padgitt was the sociology professor who first hired me for the Iowa Learning Farms project in 2004. Steve was a really good guy and I was so lucky to get to work with him before he retired. He was incredibly generous with his time as he gave me a crash course in the social aspects of agriculture. He was a great listener. After decades of Extension work, he knew agriculture and rural Iowa but he was still interested in my insights.

In the beginning, our primary task with Iowa Learning Farms was to send out a baseline survey to assess the status of conservation practices in Iowa. We needed to report regionally and so we needed a large response rate. We sent out thousands of letters and surveys. Steve signed every one of those letters. He made it clear to me that I should always hand-sign the letters I sent with a survey. Steve said that if we were going to ask the person to take the time to fill out the survey, we could take the time to sign our names. In other words, he was telling me not to ask more of other people than we are willing to give. Make the extra effort in what you do and people will respond.Now that I am director of the Iowa Learning Farms, I constantly remind myself of these principles as we are developing programming and doing our day-to-day activities. We have tried to be generous with our resources and our time. It is one of the reasons we still exist after 13 years. We try to be present in the state as often as possible through field days and community events. We make the extra effort. We could do none of this without our farmer partners.

Through the years, our farmer partners like Barry have been the living embodiment of these principles. They show up in person for others and they are cheerfully generous with their time and resources. They participate in important on-farm research and are always trying to find additional ways they can build soil health, reduce nutrient loss and improve the health of our land and water. They aren’t asking other farmers to do more than they are willing to do. They make conservation and water quality practices work on the land while they still continue to produce good yields and earn a decent living.

During this Thanksgiving season, on behalf of the Iowa Learning Farms team, I would like to thank our farmer partners for all they do on the land to make our state healthy, for all you do in being present to others across the state, and all you do to make our program a success! Thank you!

On-the-Ground Experience with Cover Crops

“What’s building organic matter worth to you?”

For Prairie City, IA farmer Gordon Wassenaar and tenant farmer Will Cannon, it’s worth using no-till and cover crops on every single one of their 1300 acres of cropland.  In a field day hosted by Iowa Learning Farms, Jasper Co. NRCS and SWCD, Wassenaar and Cannon shared their perspectives on cover crops and how they can be very successfully integrated into corn and soybean cropping systems.

Wassenaar, who has farmed for over 50 years, stated that he first got into cover crops for the purpose of protecting the soil from erosion. He started with cereal rye, broadcast seeded from an airplane.

As time has gone on, Wassenaar’s reasons for using cover crops have evolved from simply erosion control, to improving the structure and functioning of the soil — raising soil organic matter, aggregate stability, and water holding capacity. Cannon commented that on top of that, another big benefit is feeding the biodiversity of the soil, like the beneficial mycorrhizal fungi, all while growing a healthy crop.

Timing and seed-soil contact are two big factors with establishing successful cover crop stands, and it’s a balancing act between the two. Aerial broadcast seeding (or interseeding with a high clearance vehicle) allows for a larger window of time for fall growth, while drilling provides greater seed-soil contact. Today, Wassenaar and Cannon have moved to drilling all of their cover crops, ideally getting them in the ground 24 hours or less behind the combine.

When asked about the financial considerations of cover crops, Cannon responded, “We’ve got to be willing to be a little creative and inventive to make it work.”  And they certainly are.

Cannon outlined several approaches they are taking to minimize costs and improve efficiencies in their operation:

  1. Shop around for cover crop seed.
    Compare prices with different cover crop seed houses in order to get the best bang for your buck. Wassenaar and Cannon are even considering growing their own cover crop seed down the road.
  2. Consider your seeding techniques.
    Aerial broadcast seeding and custom planting carry a significant cost.  Cannon explained that they have moved to seeding all of their acres now with a drill, which has provided greater seed-soil contact, and thus improved the seeding efficiency in terms of the number of seeds that actually grow (they’ve subsequently optimized/reduced seeding rates accordingly).  They are also saving dollars through the use of a smaller 120hp tractor and a cover crop drill that was bought used.
  3. There are a lot of good programs out there that can help.
    Take a look at the conservation programs and personnel on the federal, state, and local levels that can help out.

With years of experience implementing conservation practices of no-till and cover crops, Wassenaar reflected on how much the technology advances make conservation readily doable today.

“Back in the day, we plowed because we didn’t have planters that could plant into high residue. The equipment is so good today, that now we can plant into just about any residue.  … With cover crops out there, it’s almost like planting onto a mattress.”

Wassenaar is clearly passionate about conservation, and left field day attendees with the following thoughts:

“I don’t know any other way you can farm and save your soil than with no-till and cover crops.  … I’m convinced that if Iowans take care of their soil, the soil will take care of Iowa.”

Getting Started with Rotational Grazing

Considering the transition to rotational grazing?  Wondering where exactly to start?  Ruminate on the following tips and words of wisdom for getting started with rotational grazing, shared at an Iowa Learning Farms Whiterock Conservancy joint field day this past week.

1.  Build the system to what you can afford.
Infrastructure considerations up front include fencing, water lines, tank/waterer system, and mineral feeder.

2.  Start with a system that’s manageable for you.
Pat Corey, NRCS (tenant at Whiterock/rotational grazing guru) recommends starting with a 5-6 paddock system, in which the cattle are moved once per week. That gives each paddock a 30 day rest period before the cattle return.

3.  Scale up when you’re ready. Each initial paddock can be divided in half, resulting in a 10-12 paddock system, in which the cattle are moved every 4 days.

4.  Be aware of herbicide residuals.
Always read and follow label directions, and be aware of grazing restrictions – some herbicides have up to an 18 month residual.

5.  Integrate cover crops for an additional spring food source.
Let the rye grow big enough in the spring so there is good root structure in place to balance out compaction from the livestock. At Whiterock, cattle are out on the rye from approximately April 1 until May 15, providing an excellent supplemental food source in the spring months.

6.  Try to maximize flexibility in the system! 
It’s all a learning process. Planning up front for the desired infrastructure, combined with active on-the-ground management, can yield a robust rotational grazing system, resulting in improved pasture productivity, reduced inputs, increased wildlife, benefits to soil health and water quality, and healthier herds overall.

Thanks to Pat Corey (NRCS), Darwin Pierce and Rob Davis (Whiterock Conservancy) for sharing their insights on rotational grazing!  To learn more, check out the following resources:

Nurturing the Seeds of Conservation

In 2009, the Soil and Water Conservation District commissioners challenged us to teach Iowa’s youth about soil and water. The Conservation Station and Water Rocks! program were our answers. Since that time, we have been to every county in Iowa at least twice, reaching over 100,000 people, inspiring the next generation to be thinking about and talking about conservation issues.

Starting this year, we are reaching out to the next generation in a new way, by getting college students out to our field days and talking to college students who want to farm about water quality and conservation issues.

On August 30th, we held a field day at the Gilmore City Research and Demonstration Site. If you want to learn about conservation and water quality practices that work, this research site is the place to be. A few days before the field day, we sent an email out to all the Agricultural and Biosystems Engineering undergraduates to invite them to attend. Nine students enthusiastically took us up on the offer and joined us for this excellent event (read more about it in Ann’s blog Cover Cropping on the Lobe).

During the actual field day presentations, the college students quietly listened and didn’t say much. However, the faculty and staff who accompanied them said that when they got back into the van, they were filled with so many questions and were nonstop talk about what they were seeing and learning.

It is very likely that each of these students will either farm someday or work in the agricultural industry. We are doing our part to whet their curiosity about conservation practices such as cover crops and wetlands. We are also fertilizing the seeds that will grow into a lifelong conservation ethic. We plan to offer more of these field days with college students – in partnership with both ISU and our many other outstanding colleges/community colleges around the state —  in the months and years to come.

In addition, with the help of a new grant from the Natural Resources Conservation Service and the Iowa Department of Agriculture and Land Stewardship, we are developing and launching an “Emerging Farmers” program. This program takes a proactive approach to address the need for new programming that reaches out to limited resource farmers, emerging farmers and future landowners. We define emerging farmer as someone with ties to agricultural land, not currently farming but would like to return to the farm or have a voice in its management.

In collaboration with ILF farmer partners, Iowa Beef Center, Beginning Farmer Center and Practical Farmers of Iowa, we will produce a series of emerging farmers conservation publications. Partners will collaborate to create a sustainable business plan template for the emerging farmers. We will host workshops across the state, as well as a two-day intensive emerging farmer workshop. In the years to come, we will present emerging farmer seminars to ISU agricultural student groups, as well as to community colleges and colleges across Iowa to reach those individuals with ties to agricultural land, infusing the traditional agricultural curriculum with a strong conservation focus.

The SWCD commissioners challenged us in 2009 and we continue to listen to that challenge as the Iowa Learning Farms adapts to meet the needs in Iowa for conservation education. We cannot succeed if we are not engaging and inspiring our young people. Send me an email if you would like to get involved in these efforts.

Welcome, Jack!

Hello! I am the newest member of the Water Rocks! and Iowa Learning Farms teams, so I wanted to introduce myself!

My name is Jack Schilling, and I am the first AmeriCorps Member to serve with Water Rocks! at Iowa State University. I am delighted to be a part of it. Once the program caught my eye, I knew that it would be a perfect fit for me, as it involved some of my favorite things: agriculture, the environment, music, and entertainment. And thanks to the AmeriCorps program being a part of ISU Extension and Outreach (Iowa AmeriCorps 4-H Outreach), I can continue service with 4-H, which I participated in since 4th grade.

I have lived in Iowa my entire life where I grew up on my family farm near Jefferson. On the farm, I raised chickens, cows, sheep, goats, pigs, and even turkeys and geese! I have not enrolled in a college yet, as I felt that I was not ready to take the dive in without first knowing what I wanted to do. So, I chose AmeriCorps, as it seemed to be the alternative for those who did not know what they wished to pursue yet. In my free time, I enjoy video games, music, and video production. 

I am excited to have joined the team and can’t wait to meet all of you at schools, county fairs, and more!

Reducing Soil Erosion with Cover Crops: New Infographic

Iowa Learning Farms is pleased to announce the release of a new infographic publication titled Reducing Soil Erosion with Rye Cover Crops.

This visually engaging document highlights one of the biggest benefits of cover crops — the ability to significantly reduce soil erosion. Based upon long-term cover crop work conducted by Korucu, Shipitalo, and Kaspar, colleagues at the USDA-ARS National Laboratory for Agriculture and the Environment here in Ames, this study looks specifically at one of Iowa’s most popular cover crops, winter cereal rye.

The USDA-ARS team conducted in-field simulated rainfall studies on plots with and without cereal rye cover crops, and their findings are powerful in terms of quantifying erosion reduction – 68% less sediment in surface runoff water with a rye cover crop. Further, the amount of surface runoff water decreased, while the amount of water infiltrating was found to increase with the cover crop.

This study was conducted in central Iowa, in the heart of the Des Moines Lobe, on land with a 2% slope. Substantial erosion reductions were found here with rye cover crops — consider the benefits of cover crops to reduce erosion on more sloping lands across the state!

The full infographic is available as a free PDF download on the Iowa Learning Farms website. Clicking on the image below will also take you right there.

Cover Cropping on the Lobe

Last evening, a group of 40 area farmers, Soil & Water Conservation District commissioners, and a nice delegation of ISU students from the Ag & Biosystems Engineering department gathered up at Gilmore City, Iowa for a conservation field day hosted by Iowa Learning Farms. Located between Humboldt and Pocahontas, in the heart of the Des Moines Lobe, the Gilmore City research site is home to some of the longest running research in the state on nutrient management and drainage water quality. Last evening’s field day focused on conservation practices that could be utilized in-field (emphasis on cover crops) as well as edge-of-field (bioreactors, saturated buffers, and wetlands).

Kicking things off were father-son duo Bob and Jay Lynch, who farm just outside of Gilmore City. The Lynchs have been long-term ridge tillers, and in recent years, have largely transitioned to strip tillage. In addition, they began integrating cover crops into their corn and soybean operation in 2012, and they have continued to increase cover crop usage since then. With five plus years of cover crop experience under their belts, Bob and Jay shared some words of wisdom and lessons learned with field day attendees.

 

Benefits of Cover Crops
Bob and Jay Lynch see soil health as the biggest reason to use cover crops. Bob commented, “To see the real benefits of cover crops, you need to go below the ground surface. I go out in my fields where I had rye, and take a shovel out there – the biologicals in the soil are a big deal. I hope I get an earthworm in EVERY handful of my soil! The cover crop roots give them something to eat for much more of the year. In addition to the earthworms, you have all of the other beneficial microbes, too.”

The “feel” of the soil is improved with cover crops, as well. The Lynchs spoke about cover crops giving their soil “a really nice spongey-ness.” The benefits of soil aggregation are there, too, with a cover crop – Bob referenced that the ground would come apart just like cottage cheese with a rye cover crop!

While the Des Moines Lobe is known for its rich, fertile soils, cool temperatures can pose a challenge. The Lynchs commented that cover crops help to moderate soil temperatures, and those results are consistent with data collected from the research plots at Gilmore City, as well.

The Lynchs have also seen some weed suppression benefits with cover crops – when the rye gets knee high in the spring, they’ve seen its potential for blocking out/reducing the abundance of some competing spring weed species.

 

Fall — Cover Crop Seeding
Aerial application of the rye cover crop has resulted in the best cover crop stand for the Lynchs. They emphasized that fall growth is a function of light availability, so the amount of crop canopy cover will be a big factor with the cover crops starting out.

With adequate moisture, rye cover crops will germinate quickly and begin their fall growth. Here is some emerging rye at the Gilmore City research site, just five days old!

 

Spring – Cover Crop Termination
With rye and other overwintering cover crop species, spring termination is necessary ahead of planting your row crops. The Lynchs prefer to terminate their rye via chemical in the spring. For the greatest effectiveness, Bob and Jay have found success in separating out herbicide application into two passes – even on the same day — applying glyphosate first to begin the rye termination process, then following with the pre-emergence residual herbicide.

While rolling, roller crimping, and tillage are also possibilities for cover crop termination, they require very particular conditions for success, and as Bob puts it, “It you try to till rye, you’re just making it mad … and then it comes back with a vengeance!”

 

Spring – Planting into Cover Crop Residue
When rye is growing ahead of corn, the Lynchs presented two options for termination timing: plant your crop the same day you terminate your rye, OR it needs to be dead for 14 days before planting corn.

With abundant cover crop growth, they emphasized that planter settings should definitely be taken into consideration. When planting soybeans into rye residue, the Lynchs recommend that your soybean seeds be planted using similar settings as if you were planting corn. If you use the same bean setting as you would without cover crops, you run an increased risk of the bean seeds sitting on top of the surface.

 

Management Matters
Bob and Jay concluded, “With cover crops, it all comes down to management. What works with YOUR individual farm?

 

Wetlands in the Spotlight
The evening field day concluded out at a CREP wetland just a few miles from Gilmore City, sited specifically for nitrate removal. It was a stunning end to the field day as the sun dropped lower and lower on the horizon!  The beauty of the wetland and its ability to benefit water quality clearly piqued people’s interest, as the questions and conversations continued even after the sun went down.
