Coming Soon!
2022 Acres U.S.A. Summer Intensive with Zimmer Ag
Acres U.S.A, the Voice of Eco-Agriculture. The 2021 Acres U.S.A. On-Farm Intensive with Zimmer Ag is a first-year partnership between leaders in soil health education and an event to help farmers, growers and land owners maximize their land’s potential.

A two-day, educational journey to improve your land’s value and potential.

Acres U.S.A. on-farm intensives are meant for small groups and are different from our large events in hotels and at universities, which feature classroom-style environments. Instead, our intensives are designed to be held on active, working farms to allow you to learn with all five senses, and return home with more than just textbook knowledge. Be ready to learn for two full days!

2021 Event Recap

The 2021 Acres U.S.A. On-Farm Intensive was held on July 19-20. We want to thank everyone who joined us for this inaugural event! For two days we enjoyed hearing stories and wisdom from Gary Zimmer, practical steps for and innovations in biological farming from Leilani Zimmer-Durand, and many amazing presentations featuring experts from across the biological farming spectrum.

The Program

Gary Zimmer and Leilani Zimmer-Durand, owners of Zimmer Ag, a soil health and biological farming consulting company, will lead a small group on a two-day educational journey at their famous Otter Creek Organic Farm near Lone Rock, Wisconsin. Workshops will demonstrate best practices for cover crops, soil testing, field preparation, equipment/tillage, weed & pest management, fertilizer programs, livestock integration and more. You will walk away with clear, next steps to improve your land’s value and potential.

The Venue

We know the most effective and trustworthy scenario for education is to learn on the farm, in person, with the ability to use all five of your senses – and there is no better place to do this than Otter Creek Organic Farm. Be ready to get your boots and hands dirty, to ask questions, and to learn by doing, seeing, and experiencing. *Note: This will be a COVID-19 safe event, meaning all attendees will be required to follow current CDC safety guidelines for small events.
