Inside ASABE—April 2022


In This Month's Issue:


From the Executive Director

In a little over a month, the Expo Garden Center in Peoria, Illinois, will roar with activity as ASABE’s International 1/4-Scale Tractor Student Design Competition returns as an in-person event. This year marks the 25th anniversary of the competition and, as a happy coincidence, 25 teams will vie for top honors. Special milestone events include an alumni tractor pull and an anniversary dinner. In addition to all the student interactions that make the competition such a unique learning experience, we’ll welcome the return of the awards banquet with a message from ASABE President Paul Heinemann. If you’ve never been to a 1/4-Scale Competition, come to Peoria and check it out. Our hearty thanks to all the sponsors, listed in the above link, who make the event possible.

Planning is kicking into high gear for our in-person annual international meeting in Houston, Texas. New events, sessions, socials, and meetings are being added daily to the AIM schedule. Keynote speaker John Phipps promises to get us thinking with his message "When Did We Become Cool? Farmer Perceptions of Engineers and Technology." Phipps was the long-time host of the U.S. Farm Report and regularly contributes Farm Journal video content with his "John's World" segments. His humor is particularly evident in his column on taxes and farmers, "Deep in the Heart of Taxes." 

The AIM can be a challenging conference to navigate, let alone visualize the “what’s in it for me” opportunities that it offers. That’s why we created the AIM Orientation Tool, which will debut soon. We hope this tool aids with your AIM journey. Please note, however, that the AIM Orientation Tool does not replace the conference app, which will be released just prior to the AIM and contains all the details on event times, locations, and any last-minute updates and messages.

I’m looking forward to seeing you at the AIM in Houston!

John Phipps to Keynote AIM: When Did Engineers Become Cool?

We're pleased to announce that journalist John Phipps will be the keynote speaker at this year's annual international meeting, where he will present his insights on farmer perceptions of engineering and technology.

Over his career in farming, Phipps has noticed a remarkable change in how the education and experience of engineers are perceived by farmers. For example, there seems to be a sharp difference in appreciation between scientists and engineers. Using anecdotal data from his life between two worlds, as well as some surprising attitude surveys and research, Phipps will illustrate the evolution of our image, detail the positives and negatives of this almost unnoticed shift, and offer suggestions for exploiting the advantages and protecting this esteem. 

For nearly thirty years, Phipps has been adding humor and insights to the culture of American agriculture. Educated as a chemical engineer, trained as a naval submarine officer, and seasoned by 50 years of farming on his 2000-acre Illinois farm, Phipps brings a mix of insider and outsider perspectives to his observations. He writes in Farm Journal and Top Producer magazines, creates weekly video commentary for US Farm Report, and speaks to ag-related audiences across the nation, always endeavoring in unique ways to forge better communications links for the U.S. food chain.

Nominees are being sought for president-elect and three trustee positions. Nominating committee positions will also be filled for the following technical communities and districts, including ASE, ES, ITSC, MS, NRES, PRS, District 2, and District 4.

The slate they prepare is then presented in January for ballot by the general ("corporate") membership. The committee comprises representatives from each of the Society's technical and geographic units, as well as the international membership, who currently serve on staggered two-year terms.

Those wishing to put forth nominations are encouraged to submit names and supporting materials to the Nominating committee by July 1. Current committee members are as follows, with the group each represents shown in parentheses: Sue Nokes (chair), Joel Peterson (ASE), Amy Kaleita (EOPD), Catie Brewer (ES), Dee Jepsen (ESH), Ning Wang (ITSC), Noël Menard (MS), Tiffany Messer (NRES), Morgan Hayes (PAFS), Anthony Doss (PRS), Sreekala Bajwa (E-2050), Lara Beal Moody (District 1), Johnny Grace (District 2), Elizabeth Miller (District 3), Fadi Fathallah (District 4), Nahar Nurun (District 5).

Donation Positively Impacts Underrepresented Minority PhD Students


As a tribute to their late father, and his desire to support the Society, the family of Glen Vanden Berg recently made a sizable contribution to the ASABE Foundation, specifically choosing the John C. Nye Graduate Fellowship for the gift.

The generosity of the Vanden Bergs augments that of the John Nye family and others in supporting and encouraging underrepresented minority PhD students, whose careers in agricultural and biological engineering bring diversity of experience and perspective to the discipline. 

Glen Vanden Berg was an active ASAE member from 1956 until his death in 2003. He was the 1979 recipient of the Cyrus Hall McCormick–Jerome Increase Case Gold Medal Award.

Southeast Students Rally—In Person!

SE Rally participantsIn a return to in-person events, students from eight universities traveled to Virginia Tech’s campus earlier this month to participate in the 2022 ASABE Southeast Regional Student Rally. The Department of Biological Systems Engineering hosted the event, which drew more than 100 attendees for a weekend of networking, professional development, and fun.

The three-day rally included a design competition, scavenger hunt, officer elections, and a capstone banquet, and featured three ASABE members as keynote speakers: USDA Senior Advisor Marty Matlock, Virginia Tech alumnus Rusty Unterzuber, and ASABE President-Elect Keith Tinsey. 

The next Southeast Regional Student Rally will take place in 2023 and will be hosted by the University of Florida.

ASABE Names Undergraduate Scholarship Winners

Congratulations to our four ASABE–CNH Industrial Undergraduate Scholarship winners: 

Natalie Larsson, Blacksburg, Virginia, a junior in biological systems engineering at Virginia Tech University
Katherine Skiles, Baton Rouge, Louisiana, a junior in biological engineering at the University of Arkansas
Carter West, Charles City, Iowa, a senior in agricultural engineering at Iowa State University
Jarvis Williams, Chicago, Illinois, a sophomore pursuing a degree in technical systems management/engineering technology at the University of Illinois at Urbana-Champaign

Each student was awarded a scholarship worth $2500. Students were judged, in part, on responses to questions about the shared values of ASABE and CNH Industrial, and many pointed to the constant drive toward technology innovation within the context of sustainability. "Both organizations strive to find long-term, adaptable solutions which bridge the gap between global challenges and consumer needs," wrote Katherine Skiles.

"Our undergraduate members represent the future of the profession and will soon be making their individual and substantial contributions to a sustainable bioeconomy," says Darrin Drollinger, executive director of ASABE. "CNH Industrial has been a valued partner in developing that workforce pipeline, particularly through innovative collaborations that encourage and support its emerging leaders.”

The scholarships were made possible by the generous support of CNH Industrial.
