Make it 50 years for Marion Ag Service. The St. Paul-based ag business is marking a half-century of service to the agriculture community this year. What began as a local solution for Willamette Valley growers has evolved into a nationally recognized agricultural retailer built on a foundation of trust, expertise, and deep-rooted relationships. “Reaching 50 years is something we’re incredibly proud of,” said John Hockett, CFO of Marion Ag Service.
