Image showing soil core characterized as low but and high structure.This online workshop will include recorded demonstrations with live commentary and discussion sessions. We hope this workshop will help orchardists and field staff: understand what soil health is and how to measure it; improve their understanding of management; and identify soil health priorities and questions. The original expanded in-person, hands-on workshop will hopefully be offered in the future after COVID considerations have become more manageable.
