Research conducted at the University of Vermont Proctor Maple Research Center over several years to explore a variety of methods to potentially increase sap yields from tubing systems through modifications of the lateral/dropline portion of the sap collection system.
Can fertilization of sugar maple stands lead to increased diameter growth, better crown conditions, and/or added sugar production? The effectiveness of fertilization depends in large part on soil nutrition.
Wood chips, wood pellets, and used vegetable oil can all be used to fire properly adapted evaporators. Each has advantages and challenges.
Research results from experiments on sap yield using new and used spouts.
Common problems with sugaring equipment and how to avoid them.
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.
The “small” spout, 19/64″ or 5/16″ in diameter, has been widely available to maple producers since the mid to late 1990’s as a “healthy” alternative to the traditional 7/16″ spout. While now in general use by producers in some regions, particularly those collecting sap by vacuum, the utility of these smaller spouts is still questioned by many sugarmakers, particularly those collecting sap by gravity. This article will review several studies conducted at the University of Vermont Proctor Maple Research Center comparing 7/16″ spouts with small spouts (for the purposes of this article, 5/16″, and 19/64″ will be considered equally as “small” spouts).
Research studies must follow certain rules in order for the findings to be valid. This column discusses a few of these simple rules: comparison of treatment vs. control, replication, dealing with natural variation, and statistical validity.
