Available in PDF, EPUB and Kindle. Book excerpt: S2Our recent studies of maple sap production have shown that invented tubing collection systems yield more sap than vented tubing systems, and that these increases are related to natural vacuum that develops in the unvented systems. Application of additional vacuum with a vacuum pump produced a further increase in sap yield. In these studies we used a paired-taphole type of experimental design. Two tapholes were drilled 6 inches apart on the same tree; one taphole of each pair received one treatment (vacuum) while the other was a control (no vacuum).S3.

Available in PDF, EPUB and Kindle. Book excerpt: S2In the spring of 1967, a vacuum pump was installed at a sugarbush located in Underhill, Vermont. This work proceeded in two phases: an individual-tree study designed to determine if sap could be drawn out of a tree in sufficient quantities to account for large yield differences; and a large-scale study of the effects of sustained levels of vacuum on yields from a nearly commercial-size network of tubing.

This book was released on 1968 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Though use of plastic tubing for collecting maple sap has been hailed as the greatest advance ever made by the maple sugar industry, relatively few maple sugar producers are using tubing systems. To point the way toward greater and more efficient use of tubing systems, we summarize here the results and observations of our experiments with this method of sap collection. Certainly, if the efficiency of plastic tubing can be improved it will be more widely used, and the industry as a whole will benefit. In this report we have summarized the results and observations of tubing experiments conducted by the Northeastern Forest Experiment Station that suggest some ways in which this increased efficiency can be obtained.
