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.

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.

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.

Download or read book Sap Yields from Fall and Spring Tapping of Sugar Maple written by Melvin Ray Koelling and published by . This book was released on 1968 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Some maple sap producers have wondered whether they could increase the total sap yields by tapping their trees not only in the spring but also in the fall too. Our research indicates that tapping in the fall cannot be recommended. Our study of fall tapping was begun in November 1964. Fall tapping was at least theoretically possible because temperature fluctuations like those of the normal spring tapping season occur to some extent in late fall and early winter. However, it was not known whether the volume and sugar concentration of fall-produced sap would be adequate to make such a practice feasible. Nor did we know whether fall tapping would affect the normal spring sap production from fall-tapped trees. The study reported here was set up to answer these questions. S3.

Available in PDF, EPUB and Kindle. Book excerpt: S2When sap production research was begun by the Northeastern Forest Experiment Station in Burlington, Vermont, in 1964, it became apparent that more quantified information on sap yield variation among individual trees and among years was needed to facilitate the designing of efficient experiments. One of the first projects undertaken was to record seasonal sap yields on approximately 140 individual trees on a sugarbush near Jericho, Vermont. Yields were measured in the sap seasons of 1965, 1966, and 1967. Data presented in this report are based for the most part on a random sample drawn from these trees. All sample trees were tapped with two tapholes bored to a uniform depth.S3.
