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.
Tapping guidelines written by state regulators haven’t always kept pace with changes in industry practices or understanding of the science of sap flow, and researchers are working to update tapping guidelines.
Using new or clean taps and droplines has a significant impact on sap production.,
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.
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.
In 2013 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes that would result. Most of these tests were done at the Cornell Arnot Research Forest.
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.
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.
