Actual yields in many maple operations are often lower than those achievable under optimum conditions. Dr. Abby van den Berg, Research Associate Professor with UVM’s Department of Plant Biology and Proctor Maple Research Center, presents practices to narrow this gap, from tree to sugarhouse.
Sap flow and stem pressure in sugar maples during winter dormancy depend on the expansion and contraction of gas bubbles. These gas bubbles are primarily located in the libriform fibers of wood tissues, not in the xylem vessels. Though there are gas bubbles (embolisms) in the xylem vessels, these bubbles are not the dominant drivers of stem pressurization.
Work done at the Uihlein Maple Research Forest in Lake Placid during the 2018 and 2019 maple syrup season looked at timing of tapping to best capture the most amount of sap. During this study it was found that trees tapped in late March did not yield as much syrup since they missed early sap runs. Trees tapped in January were able to capture early season sap runs but yield diminished slightly near the end of the season due to microbial plugging.
Aaron Wilson, an atmospheric research scientist, discusses the risks climate change poses to maple syrup production.
Changes in the amount of sugar in maple sap vary within a sap run, from day to day, throughout the season, and from year to year.
Presentation about organic maple defoamer research.
The effects of tapping on trees, and how to avoid overtapping.
Investigating how to best tap trees for long-term forest health and sustainable maple production.
Three-year study finds little payoff in sap yield for sugarmakers who tap in the fall.
Increasing the yield of sap from maple trees is the goal of most maple producers. While getting there isnÕt a matter of one simple thing, by following best management practices and paying attention to detail it is possible to increase sap yields, often quite dramatically.
