Because of a new approach to using nano-silver, the fact that PFA has been banned, and the desire to control microorganisms in maple sap collection systems, the University of Vermont Proctor Maple Research Center investigated the use of spouts and tubing containing antimicrobial nano-silver for suitability for increasing maple sap yield.
In attempting to establish criteria for organic certification of maple operations, there are still some wide disagreements among certifying agencies over how to regulate behavior that is unique to maple.
A vacuum pump attached to a well-designed tubing system will significantly boost sap flow compared to gravity sap collection, by increasing the difference in pressure between the tree, the source of the sap, and the tubing, where we want the sap to flow. A vacuum pump, however, will not deliver much, if any, vacuum to the trees if the tubing system is not tight and leak-free. This article gives basic instructions on how to check for those leaks, and how to fix them.
The goal of this project was to find alternative ways to reduce microbial contamination of tapholes. One approach we investigated was to use a check-valve to prevent microbial contamination of tapholes by preventing backward movement of sap from the tubing system into the taphole.
Thoughts and data on how setting taps on different aspects of a tree can impact sap yield.
Sap can be collected and syrup produced in the fall, but sugar content is low and the practice raises additional challenges for the spring crop.
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
Sugarmakers should consider tapping red maples to supplement sap production from sugar maples.
How sap pressure and flow interacts in maple trees during the sugaring season.
Tapping trees creates a wound that the trees are usually able to heal. But what is the impact of tapping on trees?
