Learn with all 5 of your senses at Otter Creek Organic Farm with Gary Zimmer, Leilani Zimmer-Durand and friends.

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

Acres U.S.A. Intensives put attendees in the field with the instructor to learn with all five of their senses. You will hear practical and useful information, see how it is applied, smell and feel the difference in healthy soil, and finally, taste food grown on the farm and prepared by a local chef. These are premium, life-changing opportunities to experience the change you would like to see on your own farm or ranch.

For Transitioning Farmers and Ranchers

A farmer or rancher with goals of decreasing the use of synthetic fertilizers or pesticides will benefit from attending. Learn from experts, meet peers moving the same direction, and take pictures and video to help document the educational experience. This is an investment in the future of your farm. You will leave Acres U.S.A. intensives with real tactics and measurables you can start applying in your operation.

About Our Content

Gary Zimmer and Leilani Zimmer Durand are consultants with decades of experience helping farmers regenerate their land around the world. From fertilizer bays to in-field compost mixing to carbon storage to soil testing, they will demonstrate the parts of their growing system that have made their Otter Creek Farm in Lone Creek, Wisconsin, a showpiece for how to adapt in today’s rapidly changing agriculture industry. Plus, walk a new 180-acre property they are just starting to transition to regenerative practices, and learn from special guests they bring in every year. They are also the co-authors of The Biological Farmer and Advancing Biological Farming.

The Savanna Institute is a 501(c)(3) nonprofit organization that works with farmers and scientists to lay the groundwork for widespread agroforestry adoption in the Midwest US. Inspired by the native savanna ecosystems that once covered much of this region, the Savanna Institute conducts research, education, and outreach to support the growth of diverse, perennial agroecosystems.

Canopy Farm Management provides tree planting and management services to farmers and landowners in the Midwest. Canopy establishes perennial crops, timber plantings, conservation practices, and integrated agroforestry systems. They combine expert staff, thoughtful design, and a mobile fleet of state-of-the-art farm equipment to cost-effectively establish and manage profitable, diverse, and resilient agroecological systems.

Canopy launched in 2022 in close partnership with the Savanna Institute. They continue to work closely with the Savanna Institute to ensure that their work leverages the latest science, state-of-the-art methods, and the most advanced tree genetics.
