Images from a 2019 on-farm instructional event in Northern California, taught by Gary Zimmer.

When we survey our audience on how they like to learn, it’s very clear: on the farm, with peers who they trust. For this reason, we are bringing you the 2021 Acres U.S.A. On-Farm Intensives with Zimmer Ag.

These are different from our large events in hotels and universities, which feature classroom-style environments. Instead, these are on active, working farms to allow you to learn with all five senses.

SEE the farm in action during production season, and put yourself right in the middle of the action.

HEAR from world-renowned experts who have spent decades bucking convention and learning farming systems that are profitable and nontoxic. Talk to your peers and other attendees about what they are working on at their farm, ranch or grow operation.

TOUCH the soil, the equipment, the plants and more. There is only so much a textbook can teach you.

SMELL the rich soil of Otter Creek Farm and learn the way odors and scents can help control the insect populations.

TASTE great food grown right there on the Otter Creek Farm and in the region.


Our on-the-farm events are designed to equip attendees with real, practical tools to grow better crops using the right chemical, biological and physical basis and then to take their land further and do more.

Instructors Gary Zimmer and Leilani Zimmer-Durand will demonstrate best practices for cover crops, soil testing, field preparation, equipment/tillage, weed & pest management, fertilizer programs, livestock integration and more.
