2022 Northern Soil Compaction Conference

January 26, 2022 - January 27, 2022


Every operation on agricultural fields has the risk to cause compaction and drag down your yields and profit.  Making each pass work for you is essential for maximizing your crop productivity year after year.

Join us at the Northern Soil Compaction Conference on January 26-27, 2022 for the latest in technical advice for alleviating your current compaction, building proven strategies to minimize your risk in the future, and the benefits you can expect.

Registration is $50 for both days.

A total of 5.5 CEUs will be available for Certified Crop Advisors (4.5 SW and 1 NM).

This event is co-sponsored by University of Minnesota Extension, North Dakota State University and Manitoba Agriculture and Resource Development.
