"In October 2013, Drs. Tim Perkins and Abby van Den Berg of the University of Vermont’s Proctor Maple Research Center
, revealed the findings of a study at a maple syrup conference in New Brunswick, Canada that sent waves through the industry. In 2010, they were studying vacuum systems in sap collection operations. Based on the observation that one of the mature trees in the study that was missing most of its top was still yielding high volumes of sap, they hypothesized that the maples were possibly drawing moisture from the soil and not the crown. Previously, they had presumed that the sap dripping from tap holes was coming from the upper portion of the tree. But, if the tree was missing most of its crown then, they surmised, it must be drawing moisture from the roots. ... They realized that their discovery meant sugarmakers could use saplings, densely planted in open fields, to harvest sap. In other words, it is possible that maple syrup could now be produced as a row crop like every other commercial crop in North America.
