Preliminary Results Emerge from Maple Sap Tubing Research

Maple research from the Northern New York Agricultural Development Program (NNYADP) may suggest a possible advantage of using quarter-inch tubing for sap collection. Pilot testing of the use of quarter-inch tubing to prevent clogging in sap collection lines in 2020 and 2021 produced promising results, though researchers warn that more seasons of testing are needed before they can be confident in the results. Quarter-inch tubing is not currently available in the maple industry, and researchers had to adapt tubing from other industries. “Over time, we would expect quarter-inch tubing would produce higher sap yields than three-sixteenths tubing and would be an alternative tubing option for producers using gravity-driven sap collection systems. The data from these Northern New York trials will tell us if that can be the case,” Uihlein Maple Research Forest Director Adam D. Wild said.
