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.
Forty two upland sugar maple trees and 59 riparian silver maples were tapped in 2003 to characterize their sap sugar parameters within the southern Illinois region.
A vacuum pump attached to a well-designed tubing system will significantly boost sap flow compared to gravity sap collection, by increasing the difference in pressure between the tree, the source of the sap, and the tubing, where we want the sap to flow. A vacuum pump, however, will not deliver much, if any, vacuum to the trees if the tubing system is not tight and leak-free. This article gives basic instructions on how to check for those leaks, and how to fix them.
Report on the microbial load of sap collected through plastic tubing systems.
It is well recognized that microbial contamination of tubing systems can result in a substantial loss in sap yield if untreated. Over a decade of research and maple industry experience has produced a range of possible strategies to address sanitation-related issues in 5/16Ó tubing systems (Perkins et. al. 2019). Although rapidly adopted by many maple producers, due to the relatively short time period in which it has been in widespread use, there is far less understanding of sanitation in 3/16Ó tubing systems (Wilmot 2018). To address this knowledge deficit, we conducted a multi-year study at the UVM Proctor Maple Research Center to examine sanitation-related losses in 3/16Ó tubing systems to determine which approach(es) might best mitigate sap losses due to sanitation.
Analysis of market for those interested in collecting and selling sap.
This spreadsheet tool helps determine the value of sap based on a range of factors.
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.
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.
Explains how sap flows in trees and the impact that tapping has on subsequent years’ sap flow.
