Exudation Pressure in Maple Trees: Comparing Simulations with Experiments
Exudation is the process whereby trees can generate a large positive pressure in stems or roots during months when the tree is leafless and mostly dormant and temperatures fluctuate above and below freezing. This article aims to provide an update on recent modelling efforts
in combination with experimental measurements from red/sugar maple trees at the University of Vermont Proctor Maple Research Center that validate the model results.

Research Update from the UVM Proctor Maple Research Center
Back by popular demand! Abby van den Berg will share results and progress from various research projects on maximizing yields and sustainability at the UVM Proctor Maple Research Center.
SapSpy keeps tabs on the sugarbush
During the 2021 season, the UVM Proctor Center tested SapSpy (www.sapspy.com), a relatively new entrant in the sugarbush monitoring field.
Ask Proctor: Defoamer
We regularly get questions from maple producers about which defoamers are the best to use. Of course, the answer is…it depends.
Timing of Spout and Dropline Deployment Has No Effect on Sap Yield
This aim of this project was to determine whether early spout and dropline deployment before tapping could be used while maintaining good sanitation levels and high sap yields.
Wound Response to Taphole Rejuvenation Practices
In response to injury from wounds such as tapholes, trees initiate processes to compartmentalize the affected area in order to prevent the spread of infection by disease- and decay-causing microorganisms beyond the wound, and to preserve the remaining sap conducting system (Shigo 1984). This results in the formation of a column of visibly stained wood above and below the wound, and the affected zone is rendered permanently nonconductive to water and nonproductive for sap collection. These processes, along with effects from microbial activity, are responsible for the gradual reduction in sap flow from tapholes over the course of the production season. There has been recent renewed interest in strategies which attempt to extend the standard sapflow season or increase overall yields through the “rejuvenation” of tapholes. As part of a multi-year experiment to investigate the yields and net economic outcomes of several taphole longevity strategies, we conducted an experiment to investigate the volume of NCW generated in response to two of these strategies.
Keys to high maple yield
Comprehensive video on how to make the most of your sugaring season, covering tapping, tubing, and efficient boiling.
Why sap may not always flow well in early season
Maple producers know that when the temperature starts to rise in the spring, sap flows can’t be far behind. But when the weather starts to warm early in the spring and temperatures seem favorable for good sap flows, they are sometimes left wondering why the sap hasn’t started to run. There are several explanations for the disconnect between warm air temperature and a lack of flow during
the early season.
