Sign up today for new Master Conservationist program!

Interested in deepening your knowledge of Iowa’s wildlife and plant communities, broadening your understanding of biodiversity, and connecting the dots between agriculture, natural resources, and conservation issues in our great state? Look no further than the newly revitalized Iowa Master Conservationist program, launching this next week!

Mount Pleasant will be hosting this pilot Master Conservationist program, running from October 5 – November 12, 2017. The newly refreshed Master Conservationist training program is being coordinated by Adam Janke, Iowa State University Extension Wildlife Specialist, in partnership with Henry Co. Extension and other local conservation personnel.

The revitalized Master Conservationist program features a hybrid flipped classroom format, including both weekly online lessons and face-to-face interactive meetings.  Themes will cover a broad range of conservation topics pertinent here in the state of Iowa, ranging from conservation history, biodiversity, forests, prairies, and aquatic ecosystems, to bringing it all together in the watershed and effectively communicating conservation.

Each of the online modules will be led by ISU faculty and staff who are not just experts in their fields, but also highly engaging presenters.  Participants will then meet in person weekly for the face-to-face training component, which will include interactive, hands-on activities and demonstrations led by local conservation enthusiasts, building and expanding upon that week’s online training. With numerous parallels to the Master Gardener program, the Master Conservationist program weaves together both learning and service in the local community.

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:

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.

The Poetry of Water

Have you heard the news? The hypoxic zone in the Gulf of Mexico is the biggest it has ever been this summer. More than half of Iowa’s waterways remain impaired. Iowa’s legislators can’t seem to agree on means for funding practices that would help.  It hasn’t been a great year for water quality so far.

It isn’t that we don’t understand the problems or the solutions. There is plenty of information out there. Lots of smart people are speaking about the science of water quality, studying the impacts of agriculture, discussing economics issues, and monitoring water. This information is important and necessary.

It’s more that we still lack the will to create lasting changes to allow for cleaner water, more habitat and healthier soil. Perhaps we need to move beyond the technical and economic talk and express the poetry of water.  Throughout our history it has often been a well-turned phrase, public speech or essay that has motivated action in others.

Back in 2008, when Jerry DeWitt was first appointed as director of the Iowa Learning Farms, he and I went on a tour of the ILF partners who were hit hardest by heavy rains and flooding. When he got back to his office, he wrote an essay that began, “Yesterday I cried for the land. Today I must speak for the land.” You can read the full text on p.3 of the archived Leopold Letter newsletter: http://publications.iowa.gov/18617/1/LeopoldLetter2008Summer.pdf

What followed was a poetic expression of Jerry’s emotions in seeing fields eroded down to bedrock—not your typical academic writing. For several weeks after that essay was published, it was brought up in meetings, including the Soil and Water Conservation Districts annual meetings, and during random conversations. It became a call to action.

Who is writing poetry for water?

Jerry showed that aptly expressed words get things done. Words make us uniquely human but poetry is what speaks to our higher angels. Writers like Rachel Carson and Aldo Leopold put language to good use on behalf of lasting, life-altering environmental change.

Who among us isn’t familiar with Carson’s Silent Spring (1962) that moved us with its craft and motivated us as a nation to change our use of pesticides? Or think of all the folks who became conservationists or wildlife specialists inspired by Aldo Leopold’s Sand County Almanac (1949) with his essays on the land stirring a conservation ethic. I was only seven years old when my older brother read me Dr. Seuss’s new book, The Lorax (1971), and nurtured in me a life-long desire to speak for the trees. The poetry of these authors and so many others have inspired generations to think and live in the world differently.

We don’t need any more ordinary prose. We are bloated with words today. Everyone seems to be “expressing” themselves on social media and other online outlets. Could a Carson or Seuss or Leopold get through all of the word pollution today?

Our lakes, rivers, streams and underground aquifers need more poetry in the tradition of Carson, Seuss and Leopold—writing that expresses feelings and ideas that allow you to see beyond what is right in front of you to get at a deeper truth or beauty.

Only the best among us are brave enough to write poetry for poetry is too important to be left to professionals.

Two Black Hawk County watershed projects, in partnership with the University of Northern Iowa’s Environmental Literature class during the spring of 2017, brought us poetic stories of people in their watersheds. The work is called “Beauty Outside Our Doors” and is available as a free PDF download.  The essays are personal and purposeful and speak to a greater truth about the state of our environment in Iowa.

It would be great if every watershed improvement project in Iowa could take Black Hawk County’s lead and do a similar project with the residents in their watersheds.  It would be inspiring to see similar books written across the state.

BUT, you don’t need to live where there is an active watershed project in order to speak for water. Each one of us is called to find the poet inside of us and let people know the truth about our waterways. We are water and water is life. Clean water is essential to our existence. We ignore this at our eventual peril. After you write your piece, share it with whoever will listen. It is time for life-altering change. The water (and all of life) is counting on us.

Guest Blog: Fair Eats

Our final summer guest blog post comes from high school intern Josh Harms, who will be a senior at South Hamilton this fall. Take it away, Josh!

Hello, my name is Josh Harms. I am a high school intern with Iowa State’s Water Rocks! program this summer. While I have been traveling across the state of Iowa to many different county fairs, I have had the privilege of experiencing a diversity of fair food, everything from the basic corndog to the amazing tacos and black raspberry ice cream at the Wright Co. Fair. I also tried pulled pork nachos at Badger Fest, fried cheese balls at the Central Iowa Fair, a pork tenderloin at the Washington Co. Fair, and a mango smoothie followed by mini donuts at the Cherokee Co. Fair.

Throughout all the fairs I have attended, the Wright Co. Fair had the best food by far, but I guess that could just be my bias towards tacos and ice cream, especially black raspberry! After eating all these different foods, I still enjoy all the unique foods that Iowa’s fairs have to offer, but I think I maxed out my capacity for fried foods when I had chicken tenders, fried cheese balls, and a funnel cake all in the same trip!

As my internship is coming to a close, I have really enjoyed the county fairs and camps I’ve been to, and I have also learned a lot about the environment in Iowa. One thing that is really memorable is that one gram of dog poo has 23 million bacteria. Also, sediment is the #1 pollutant in Iowa. Actually, in Iowa, we lose 1 inch of topsoil every 20 years and we gain that 1 inch back in 500-1000 years. Overall, I have enjoyed working with the other interns along with traveling to all the different fairs across the state of Iowa. I would also like to thank the staff at Iowa State University for this wonderful internship opportunity!

Internship offers new perspectives, new direction

Today’s guest post in our Water Resources Internship blog series was provided by Andrew Hillman. Hillman grew up in Bettendorf, Iowa, and went to school at Pleasant Valley. He will be entering his junior year at ISU in the fall, majoring in Biosystems Engineering. Read on for his unique perspectives in the internship coming from an urban background!  

It has been a fun, wild ride in a way for me this summer. Coming from a completely urban background in the Quad Cities and starting this internship, I had little to no idea about any of these issues, or really anything about agriculture at all to be honest. But, from the pre-job training to all the experiences I have had this summer, from field work to outreach events, I have learned quite a bit. I never thought before this summer that I would ever be excited to go out and see things like bioreactors and restored oxbows, but here I am!

I have always been somewhat informed about environmental issues, but the thing that I have enjoyed the most about this summer is that I now have more nuanced and informed opinions about issues. And I can actually draw on my own experiences now, which is very neat. I knew that erosion and nutrient loss and runoff were environmental issues on the forefront in Iowa, but now is the first time that I can say that I feel personally connected to these issues, which is always something I felt that as an Iowan I should be doing, but never knew enough about.

Going to Iowa State University for Biosystems Engineering, I quickly was exposed to how little I knew about agriculture in Iowa, and so this summer has helped me fill a gap in my knowledge that was fairly noticeable compared to some of my peers. Now that I have experience going out to a field, seeing cover crops and collecting water samples, some of the things we talked about in my ABE classes are suddenly much clearer to me now that I have the context.

Something specific that I did in my ABE 218 course was build a table-scale system for reducing nitrate levels in water. Now that I have seen an actual bioreactor site, and presented the model bioreactor that Extension has, I have a greater appreciation for that project and the things that I learned while doing it. I even had the opportunity to work with Chase, one of the other interns, to come up with a preliminary design of our own for a model bioreactor to possibly be placed in one of our conservation trailers in the future. Edge-of-field practices like bioreactors are really fascinating to me.

Back on July 12, I had the opportunity to go to my home county for a Scott County soil health and cover crops field day. This was a great event for me, because growing up in Bettendorf, I really did not associate Scott Co. with much farming compared to the other places I had been in Iowa. It was interesting to see all the things that farmers in my area were doing to further soil and water quality goals.

The host location, Cinnamon Ridge Farms in Donahue, Iowa was amazing. It was eye-opening to hear the owner talk about all the strategies he was using, including his methods for integrating cover crops into his operation. Because their operation does tours year-round, including tours to farmers from all around the world, he had a unique perspective on many of the government cost share programs that are available to farmers, noting that there are not very many countries in which the government will pay you to adopt a farming practice. I think that this is very important, and one that people should keep in mind as Iowa communities look to adopt more parts of the Nutrient Reduction Strategy in the future.

I am currently in the Biorenewables option right now in Biological Systems Engineering, but after my experiences this summer with the Iowa Learning Farms, I am seriously considering switching my option so I can continue to learn more about the issues that I have been exposed to this summer! As an engineering student, this is where I can see so many opportunities to get involved after graduation.
