It generally takes the fall release of the special issue of Resource magazine for me to notice that we are fully in “back to school mode.” We rotate between "Discover," which features agricultural and biological engineering grads, "Explore," which focuses on those who earned agricultural systems management (ASM) and similarly named degrees, and the "Capstone" senior design issue. The experiences and contributions these recent grads write about are inspiring. The ag systems programs are less theoretical and more applied, with an emphasis on hands-on learning. This can-do mindset often leads ASMs to have very diverse and exciting careers, like Auburn grad Adam Lenhard, who is working in the music industry managing artists, scheduling venues, and performing himself. Watch for the "Explore" issue to hit the virtual newsstand in the coming days.

I’m pleased to report that CNH Industrial is once again offering four $2,500 ASABE scholarships to agricultural systems management and agricultural and biological engineering undergraduates enrolled in U.S. or Canadian programs. It’s easy to apply. Be sure to submit your application by October 31, 2023.

The USDA NRCS recently released episode 1 of their "Legends" series focusing on individuals who have been pivotal to watershed conservation work throughout the nation. ASABE Fellow Larry Caldwell is featured in this episode and he does an excellent job describing the Watershed Protection Program and his career’s work. Watching this 32-minute video is time well spent!

Dues Rise but Your ASABE Membership is More Valuable Than Ever

ASABE leadership makes every effort to manage the financial resources of the Society responsibly, and we consciously limit member dues increases. Our commitment to maintaining the highest-quality services and products, however, means that occasional increases are all but unavoidable.

Such was the case when the ASABE Board of Trustees completed its periodic dues-review process and determined that an increase is necessary. Renewal invoices for 2024 will reflect an increase across all dues categories except for undergraduate and graduate students.

Be assured that we will continue to control expenditures and reduce expenses whenever possible, while providing the highest-quality support and service to our members. Over the last few years, we've expanded our commitments to members, hosting more specialty conferences and extending our support of students and early-career members. We've widened efforts to foster partnerships within and external to ASABE. We've offered additional assistance to those members seeking professional licensure and for those looking to fulfill their licensure requirements. And we'll continue to seek out opportunities to leverage our respected Standards program, as with our recent accreditation as a Canadian Standards Developing Organization.

We'll continue to seek the highest return on benefits for Society funds in order to serve our membership and to strengthen agricultural and biological engineering as a profession.

In Memoriam — Edwin Eisele

Edwin Eisele photoEdwin Eisele, 51, of Olathe, Kan., passed away on Sunday, July 30, in his home, surrounded by family.

Eisele was born September 15, 1971, in Ottawa, Kan., to Karl and Twilla Eisele and his childhood on the farm shaped his skills and passions. He graduated from Ottawa High School in 1990, attended Bartlesville Wesleyan College for two years, and went on to earn his BS and MS degrees in biological and agricultural engineering at Kansas State University.

After graduation Eisele worked for John Deere, where his expertise in transmissions and hydraulics were put to use on numerous tractor programs. He was issued a patent, developed new technologies, adventured in Europe during a three-year assignment in Mannheim, Germany, and made many lifelong friends along the way.

Eisele met his future wife, Casee, at Kansas State University, and they married on December 27, 1996. They were blessed with three sons, Spenser, Lance, and Trent. The family enjoyed many exploits together, and Edwin passed along his special kind of humor and love of K-State sports to his boys. They spent many happy years in Waterloo, Iowa, sandwiching the three years in Mannheim, Germany, and the past decade in Olathe, close to family and the family farm.

He is survived by his wife and sons, his parents, two brothers, and a host of loving aunts, uncles, cousins, nieces, nephews, and extended family.

Memorial suggestions include a fund established for Edwin L. Eisele at the Kansas State University Foundation. Indicate fund M47449.

Eisele was a 30-year member of ASABE.
