Marion Ag has been serving farmers, nursery-greenhouse growers and wholesale fertilizer re-sellers for 50 years. In 1967, Robert Hockett branched out from full-time farming, joined with Allied Chemical and became one of the first liquid fertilizer distributors in the Willamette Valley. In 1976, Hockett teamed up with four other local farmers to form Marion Ag Service Inc. Two years later, Hockett bought out his partners and Marion Ag Service became the largest distributor of Ash Grove Lime in Western Oregon.
