A Huge Thank You!

ILFHeaderOn behalf of the Iowa Learning Farms team, I would like to thank all of our hosts, speakers and partners for an awesome 2018 Field Day season. This year our 24 field days and workshops were attended by 1,134 farmers, landowners, government employees, students and educators, media and agribusiness staff. The topics covered included: cover crops, grazing cover crops, soil health, strip-till/no-till, bioreactors and other edge of field practices, water quality, Emerging Farmers and events for women landowners.  Implementing these practices on our landscape is so important in helping us reach our Iowa Nutrient Reduction Strategy goals.

Keep an eye out for mail from us this January! We will be mailing a brief survey to all farmers/operators and landowners who attended an ILF-sponsored field day or workshop.

Be sure to check out our events page on our website to attend a 2019 event near you.

3 Practices, 1 Field Day

Q: Where can you see a bioreactor, saturated buffer and wetland all working together to reduce nitrate leaving agricultural land?

A: At the Land Improvement Contractors Association (LICA) farm near Melbourne, Iowa.

We had great weather for our field day yesterday at the LICA farm that allowed farmers, landowners, contractors, and state agency staff the opportunity to see these practices in action first hand. The saturated buffer installation was started the day before the event and was left open to allow visitors a chance to see how the process occurs.

Attendees rotated through three stations to learn more about each of the practices installed on the farm and got a chance to view what goes on underground with a stop at the Conservation Station On The Edge. There were great questions and discussions as we work together to ramp up the installation of these practices all across the state.

Bioreactors: Effective Tool for Reducing Nitrate Loss

Roger and Louise Van Ersvelde are passionate about conservation and land stewardship on their farm east of Brooklyn in Poweshiek County. They shared that passion with just over 50 field day attendees and highlighted the newest practice they are using on their farm – a denitrifying bioreactor.

“Installing the bioreactor was the next logical step for helping do my best to help make sure the water leaving our farm is as clean as possible.” Roger Van Ersvelde, Poweshiek Co Farmer.

Their denitrifying bioreactor was completed fall of 2017 with assistance from the local Natural Resource Conservation Service staff and Poweshiek County Soil and Water Conservation District. To measure the performance of the bioreactor, they partnered with Andrew Graham, Assistant Professor of Chemistry at Grinnell College, to collect and analyze paired samples collected from the inlet and outlet structures.

Some key takeaways from the data results:

  1. Average nitrate removal is 46% from March-July 2018.
  2. Observed higher removal efficiencies during lower flow times (March-Early May and again in July). Removal efficiencies ranged from 10-30% during high flow times.
  3.  Removals of total N are pretty comparable to nitrate removal.  This indicates the bioreactor is promoting denitrification to primarily N2 and not generating ammonia.
  4. The high nitrate removal tends to coincide with high dissolved organic carbon concentrations, suggesting that the extent of denitrification is strongly dependent on the amount of readily degradable carbon.

“If you care about the environment, bioreactors are a great practice – even with no direct benefit to the landowner,” commented Dave Maxwell, contractor who helped install the bioreactor. “Thank you Roger and Louise.”

To learn more about bioreactors and other edge of field practices, visit our website for videos, webinars and print materials and attend a field day near you! Contact Iowa Learning Farms if you’re interested in talking about edge-of-field conservation practices on your land!

Request the Conservation Station On the Edge Trailer for Your Next Event!

Have you heard of a saturated buffer or bioreactor, but aren’t sure how they work to reduce nitrate loss? Are you curious about installing them on your farm or in your watershed?

To help answer those questions and more we are excited to announce the launch of our newest Conservation Station – On The Edge!

The Conservation Station On The Edge features a saturated buffer and bioreactor model to demo the edge of field practices and discuss how they reduce nitrate entering Iowa’s water bodies through the natural nitrate removal process.

Designed for farmers and landowners, this new trailer is available to request for your upcoming field day, workshop or community event. It is staffed by the Iowa Learning Farms team, offered free of charge and is available for single-day events. Trailer availability begins June 1, 2018.

Request the Conservation Station On The Edge today by emailing Liz Juchems at ejuchems@iastate.edu

Why Field Days Matter

Through our evaluation work since 2004, we have found that there is a relationship between attending field days, adopting conservation practices and influencing other farmers. We call this our Field Day Success Loop.

SuccessLoop

Networkingpercentage

Iowa Learning Farms has learned the importance of taking a closer look at who among field day attendees is networking with other farmers and discussing conservation ideas. Since 2013, the number of farmers who attended field days and networked conservation ideas with other farmers continues to increase – from 65% in 2013 to 68% in 2017.

A follow-up question on our year-end evaluation asks “How successful were you?,” and asks if farmers were able to influence zero, one, or two or more people when they networked conservation ideas with other farmers. Of those attendees who networked in 2017, 60% reported that they were successful in influencing at least one other person.

We know that some farmers network about conservation ideas and others do not. Certain factors make respondents more likely to connect with others and network about conservation ideas. Those respondents who have more years of experience with cover crops and those who attend more field days are more likely to report networking conservation ideas. Particularly in 2017, respondents who farm a larger number of total acres were more likely to report networking conservation ideas.

Networking

Multiplier Effect

Field day attendees are networking with their peers, influencing farmers who did not attend the field day, thus creating a multiplier effect. In 2017, 68% of farmers who attended an ILF event said that they networked. As a result, farmers are extending influence to 55% more farmers than attended the event. That’s a $1.55 value for every dollar invested in ILF. Field days make sense!

Evaluation key to effective field days

You planned your event – lined up the space, speakers, meal – and had a great turnout. Congratulations! You’re done now right?

Not quite…

How do you know if your event was effective in meeting your outreach goals? What could have been done differently to improve the effectiveness? Asking for attendee feedback is a useful evaluation tool that can be used to make decisions on what worked well and what doesn’t. In addition to self-reflection on the event, asking for attendee feedback is one of Iowa Learning Farms’ key tools for planning and holding well attended and effective events.

DSC_1312Through our two-week follow up evaluation we gather feedback on the effectiveness of the field day to help us improve future events. Using a five point scale, attendees are asked to rate the overall quality of the field day, effectiveness of expert presentations (ILF, ISU Extension and Outreach, NRCS, PFI, etc.), and effectiveness of farmer presentations.

All three categories saw improvement over 2016 numbers. The effectiveness of expert presentations saw a 10% increase over last year in the people who considered it excellent and the overall quality of the field day or workshop metric saw an 8% increase over last year in the people who considered it excellent.

Effectiveness

In addition to the information above in our Year End Evaluation Report, we also compiled our Individual Field Day Report. This report breaks out the evaluation responses by event, as well as how far attendees traveled to attend the event to help with field day promotion efforts – see map below.

Summary of 15 16 and 17 Distance Traveled by Crop Dist

An example two-week evaluation is available in our Field Day Marketing Toolkit and we encourage you to modify it and use it for your own event.  We are currently revising the evaluation to add more specific questions aimed at improving program content and format. This will be included in the Toolkit update later this spring.
