The 3/16 phenomenon
Using smaller-diameter tubing can create a natural vacuum which can increase sap production. This article details some research into this method of sap collection, and offers tips on some practical applications.
A Mathematical Model for Maple Sap Exudation
Sap exudation refers to the process whereby sugar maple trees (Acer saccharum) are capable of generating significant stem pressure in a leafless state, something that occurs to a lesser extent in only a few other related species such as birch and walnut. This exudation pressure is what causes maple sap to flow from a taphole in sufficient quantities to be harvested and processed into syrup. Exudation has been studied for well over 100 years and has been the subject of many scientific studies, but there is as yet no definitive explanation for how such large pressures can be generated in the absence of transpiration (i.e., when no photosynthesis occurs to drive the flow of sap).
Cleaning Tubing Systems
There are a number of ways to clean tubing systems to avoid microbial contamination of tapholes and sap.
Testing tapping depth vs. sap yield
Results from research into the impact of tap hole depth on sap yield.
Imidacloprid contamination of maple sap following Asian longhorned beetle quarantine treatment
Both the Asian longhorned beetle and the use of imidacloprid to protect sugar maples from this pest pose a threat to maple syrup producers.
Some in maple season and out of season tests on 3/16″ maple tubing
3/16″ tubing can provide some yield benefit by creating natural vacuum. That benefit will be directly related to the elevation drop of the lateral line.
Collect More Sap Without Vacuum Pumps
Using 3/16″ tubing can create non-mechanical vacuum that can increase sap yield.
Crown Release Equals More and Sweeter Sap
Have you ever wondered why open grown trees produce more and sweeter sap than the ones growing close to each other? To answer these questions, I would like to share with you from my 37 years of experience in forest management.
A New Take on Sap Collection
A new method of gathering sap from sugar maple saplings is being tested.
