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.
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.
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.
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.

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.
Sap Flow, Wounding, & Compartmentalization in Maple
How does a tree respond to the wound created by a taphole, and what does that mean for future sap production?
Sap flow, wounding and compartmentalization in maple
Explains how sap flows in trees and the impact that tapping has on subsequent years’ sap flow.
The Northeast Maple Economy: Crop Distribution and Outlook
As the US domestic maple syrup crop continues to grow the influence of different scales and types of business can shape local communities and national trends. Survey results presented here demonstrate the dramatic difference in the scale of maple enterprises as represented by tap count and the resulting working forest acres these businesses utilize.
