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.
Since check valve adaptors and spouts reduce sap backflow, this research studied whether or not dropline replacement is as important to improving sap yield when using these taps.
This article is intended to accompany the Tapping Zone Model available to download at the University of Vermont Proctor Maple Research Center (UVM-PMRC) website. It provides a general explanation of the model and how it can be used. The model can be used to estimate the chances of hitting conductive and nonconductive wood when tapping, and this can be used to assess the sustainability of current or planned tapping practices.
Many studies have demonstrated the benefits of replacing droplines on sap yields. The research outlined in this article outlines several replacement strategies to allow producers to determine the cost-effectiveness of each.
A model that calculates the proportions of conductive and nonconductive wood in the tapping zone of a tree over time given user-input values for tree diameter and tapping practices.
For several years, PMRC researchers conducted research on the collection of sap from small-diameter maple trees. This document outlines the basic concepts, techniques, and applications of this type of sap collection.
The overall objective of this work was to determine whether existing Conservative Tapping Guidelines are appropriate and likely to result in sustainable outcomes when used with sap collection practices that result in higher sap yields.
Calculates projected sap yield and net profits based upon known relationships between tubing aging and various management strategies under vacuum conditions.
An Excel spreadsheet that can be used to determine the effects of replacing or cleaning spouts and droplines on sap yield and profit.
A presentation on the potential value of adding birch syrup production to an existing maple operation.
