Is Tapping Below the Lateral Line A Good Idea?

This research was conducted to determine whether tapping below the lateral line in vacuum tubing operations results in the same quantity of sap from a taphole as normal (above the lateral line) tapping, and thus whether tapping below the lateral is a reasonable management alternative which might be employed to increase the size of the tapping band in maple sap production. It will also inform us as to any tradeoffs (reductions) in yield that might result from this approach.

Sap Collection from Small-Diameter Trees

For several years, we 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.

Do Not Use Isopropyl Alcohol as a Maple Sanitizer in the U.S.

Regardless of the availability and guidance provided, maple producers should clearly understand that the use of isopropyl alcohol in maple tubing systems anywhere in the United States is a violation of federal law.

A Summary of Research to Improve Vacuum in Maple Tubing Systems

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.

What’s trending

The 2012 USDA Census of Agriculture reveals trends in growth for number of producers and number of taps in many states.

Growth Rates of Sugar Maple Trees Tapped for Maple Syrup Production Using High-Yield Sap Collection Practices

The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.

Comparison of Digital Refractometers for Use by Maple Producers

The purpose of the present experiment was to test the precision of a variety of digital refractometers available to maple producers. Additionally, the effect of temperature on refractometer accuracy and precision was investigated, in order to assess the reliability of the automatic temperature compensation feature now present in the majority of refractometers.
