David and Ron Rosmann

Join lifetime PFI member Ron Rosmann, Eric Madsen of Audubon, Iowa, and cultivator specialist Dale Kumpf as they discuss all aspects of Buffalo cultivators and planters. During the event, Ron and Eric will share their organic weed control experiences and cultivator know-how while showcasing their Buffalo equipment. Learn how to improve cultivator settings and fine-tune a planter, and see a cultivator in action. Though Buffalo equipment is featured, concepts and strategies discussed will be relevant to any high-residue cultivator. Kathleen Delate will talk about weed control and crop rotations in organic systems.
