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.
Why are my tapholes leaking and what can I do about it? (Part 2) Being able to recognize what is really a leak and what is not takes some time and thought and experience. This article offers some tips.
Why are my tapholes leaking and what can I do about it? (Part 1) There are often several issues involved in leaking tapholes, and sometimes the applied remedy itself turns out to be the actual problem.
Should I use 3/16″ or 5/16″ tubing? One of the first questions maple producers face when deciding to tube (or retube) a sugarbush is whether to use 3/16″ or 5/16″ tubing. This article explains some of the general rules that can be helpful in narrowing down the pros and cons of each approach.
The University of Vermont Proctor Maple Research Center and the Cornell Maple Program Arnot Forest conducted a multi-year study examining several common sanitation strategies and assessing the effects on sap yield, attendant costs, and resulting net profits. The following graphs briefly summarize the results of this work.
These 9 variables are intended to help a potential commercial maple producer evaluate the relative merits of one or more selected woods for profitable maple production. A poor or medium rating does not mean that the woods should not be tapped but that production costs in money or labor will likely be higher or greater investments will be necessary to allow the sap collection to be established relative to other sites. Some problems may be avoided if the potential producer is a creative problem solver. Small-scale producers and hobby producers have less emphasis on financial return, so these variables are relevant but perhaps not weighted as heavily.
The advent of plastic tubing systems to collect sap has eliminated several problems associated with the traditional bucket system. However, plastic tubing systems also present some problems of their own. Sap quality problems arise if the lines sag and the sap lingers within the tubings or the large conduits. In addition, the warming effect of the sun increases the tem perature within the tubing to optimum levels for microbial growth and sap flow may decrease because of “organic buildup” on the internal tubing walls. This buildup is a result of the adhesion of microorganisms to the tubing walls.

An important part of beginning or improving the tubing system in a maple enterprise is to have a good estimate of just how much the project will cost. Though there are many variables in installing a new or replacing an old system the cost of materials is predictable. Two factors allow you to make a reasonable estimate of what a sap collection system will cost in materials. The first is the number of taps per acre. The second is the density of trees.
This research was designed to examine age-related losses in sap yield in tubing systems operated under vacuum, and to explore different strategies to reduce tubing microbial contamination induced sap yield losses.
