Research and Field Crops Director
Stefan Gailans joined Practical Farmers of Iowa in August 2013. An agronomist by training, Stefan’s primary responsibility is to manage the Cooperators’ Program, Practical Farmers of Iowa’s vehicle for conducting on-farm research on the issues and concerns deemed most important by our members. He also coordinates field days, conference sessions and work shops for PFI’s field crops program.
Stefan grew up in southeast Wisconsin and gained an appreciation for the environment after spending many hours hunting and fishing with his family. This appreciation for the environment birthed a curiosity in the intersection of the natural landscape and the ever-present agricultural landscape. Stefan pursued this curiosity, receiving his BS degree in Crop Sciences from the University of Illinois in 2005 and an MS in Sustainable Agriculture and Crop Production & Physiology from Iowa State University in 2010. In 2013, he completed his course work for a PhD in the Agronomy Department at ISU. His primary research interests were cover crops, third crops and alternative crop rotations.
Stefan enjoys calling Ames (and Iowa!) his home and looks forward to working with farmers across the state and addressing their research concerns. When he’s not thinking about crops, Stefan enjoys listening to music, seeing local bands with friends, listening to the radio, reading science fiction novels that envision interesting (and intriguing) futures, spending time outdoors, and cooking & eating quality local food.
Cover crops in Iowa are typically seeded in late summer or fall. The most common cover crops are winter small grains like cereal rye or winter wheat. But farmers are increasingly interested in diversifying the cover crop portfolio in Iowa. In this trial, cooperators wondered: Can frost-seeding small-seeded brassica species into crop residue be an effective spring cover crop strategy? Because mustard and rapeseed have relatively small seeds, some have wondered if frost-seeding these into crop residue in the early spring could be an effective 40- or 50-day cover crop strategy. Read the new report here: Spring-Seeded Brassica Cover Crops.
Continuing work from the previous two years, Practical Farmers of Iowa and partners conducted another round of oat variety trials in 2017. Fifteen varieties were screened at two Iowa State University research farms (Kanawha, Nashua) and one PFI farmer-member farm (Wayne Koehler, Charles City) Find the new report here: Oat Variety and Fungicide Trials 2017.
- The variety Antigo had the highest test weight at each location (>38 lb/bu) but was also among the lowest yielding varieties. Reings scored a test weight of 38 lb/bu at Kanawha
- Application of fungicide did not improve oat yield or test weight for the four varieties tested at Nashua

The video features Chris, as well as Dr. Jill Clapperton, discussing cover crop practices and benefits to soil health.

In Iowa corn-soybean production systems, cover crops are typically aerially seeded into standing crops around the time of physiological maturity or drilled immediately following corn or soybean harvest. Previous on-farm research conducted by Jack Boyer has shown that seeding cover crops earlier in the fall can translate to greater fall and spring biomass. This may present the opportunity for more diverse cover crop species selection. With this in mind, farmer-cooperator Jon Bakehouse wanted to investigate how he could seed cover crops earlier than normal in a corn-soybean system and more successfully include a diverse array of cover crop species. To accomplish this, Jon planted early maturing varieties of corn (104- or 105-day) and soybean (1.0 group) in an attempt to harvest earlier in the fall and seed cover crops earlier in the fall.

This year marks the 30th anniversary of Practical Farmers’ Cooperators’ Program. Since 1987, members have been conducting on-farm research to answer questions they have about their farming operations. It’s one of the ways we accomplish our mission: Strengthening farms and communities through farmer-led investigation and information sharing.
The Research Protocols forms outlining research projects for the 2017 season are now posted on our website. They are identified by program area (Livestock, Horticulture, Field Crops) and you can view them here:
These projects were designed by farmer-members and are currently being conducted on our members’ farms by the members themselves. The protocol forms are designed to give a snapshot of the methods and experimental designs our farmers are using to conduct research to answer their most challenging questions on their farms. Eventually, these projects are completed and documented in freely available research reports.
On-farm research through our Cooperators’ Program has long been a fundamental piece of the Practical Farmers of Iowa fabric: It is one of the primary ways members share their knowledge and experiences with one another. This year, topics range from rolling cover crops ahead of soybeans to feeding pelleted small grains to hogs to lettuce variety trials for summer production. The range of topics is a testament to our “big tent” and represents the ever-present curiosity that makes a Practical Farmer.
The fifth and final iteration of Practical Farmers’ Cover Crop Variety Trial has just been released: Cover Crop Variety Trial, 2016-2017.
As with the previous iterations, cooperators hand-seeded cover crops into small plots and assessed groundcover in the fall (prior to hard freeze) and the following spring (prior to termination). Cover crop entries studied in 2016-17 are shown in the table below. Read on to learn more about the recent iteration of the trial which was conducted by seven cooperators across the state.
According to the 2014 Organic Survey, Iowa ranked No. 10 in organic sales, but the state has since fallen out of the top 10. Given that organic sales rose nationally by 13% from 2014 to 2015, though, interest in organic farming and produce remains strong among consumers. Interest also remains strong among farmers in Iowa. As such, Scott, Jack and Linda Ausborn hosted a field day near Ida Grove to address the organic transition process, crop rotation considerations and weed control tactics. “Farming organically is fun and challenging,” Scott told those attending. “It has also connected us to a very experienced network of farmers to learn from and go to for help.” The field day was held in partnership between Practical Farmers of Iowa and the Iowa Organic Association.
Read on to learn more about this field day below. You can also learn more about Scott and his family’s farm in this episode of our podcast, On-Farm: Conversations with Practical Farmers.
According to Iowa State University, 53% of the farmland in Iowa is rented. That is to say, the majority of the farm acres in the state are farmed by people who do not own that land. That does not, however, mean that those who own farmland but don’t farm it themselves cannot do their part when it comes to conservation. Case in point are Maggie McQuown and Steve Turman who own Resilient Farms near Red Oak and hosted a field day on June 15. The two shared how they have implemented numerous soil and water conservation strategies on their land by working closely with their farm operators, Bryan and Lisa Huff. As we learned at the field day, these strategies include cover crops, riparian buffers and prairie strips.
If cover crops can successfully be established when interseeded into corn in June, this may permit farmers to use existing equipment (rather than high-clearance machines or airplanes); may permit the use of more diverse cover crop species; and ultimately may increase the amount of cover crop biomass produced. Last year, PFI farmer-cooperator Jack Boyer interseeded a 4-species and 6-species cover crop mix into seed corn at the V4-V6 stage in randomized and replicated strips. He intended to see if the cover crop could persist underneath the seed corn canopy and see how much biomass could be produced in the fall following harvest.

We continue our celebration of Practical Farmers of Iowa’s Cooperators’ Program’s 30th anniversary with another installment of our “Better Know an On-Farm Research Project” series. Previously, we featured Vic Madsen discussing strip trials that investigated N fertilizer rates for corn and Dave Lubben discussing some of the biological and alternative amendments he tried for corn and soybeans. Now we train our focus on some of the earliest vegetable research trials which began in the late 1990s. For several years, lifetime PFI member Angela Tedesco ran Turtle Farm near Granger, which offered CSA shares to customers, and was among the first to conduct on-farm research as part of the emerging horticulture crowd among PFI’s ranks at the time. As Angela tells it, she was looking for ways to expand her CSA but conserve space with transplants in the greenhouse.
