In mid-April 2010, an invitation to participate in a survey was sent to subscribers of two maple forums. The survey was designed to get some basic information about the operations of the respondents, to describe sanitation practices (changing tubing, spouts, etc.) and to get feedback from users about the Leader Check-valve adapter.
Research results from experiments on sap yield using new and used spouts.
Research studies must follow certain rules in order for the findings to be valid. This column discusses a few of these simple rules: comparison of treatment vs. control, replication, dealing with natural variation, and statistical validity.
A spreadsheet to calculate costs and returns of using vacuum sap collection systems.
A summary of a presentation on energy efficiency in maple production.
Root starch has been used to estimate tree vigor and health with some success. A visual method of starch determination similar to that already used for roots has been undertaken for twigs. If successful, this method would simplify the process of assessing overall tree health and vigor in sugar maple trees.
Tree growth rate can be an important indicator of how well the tree will heal from tapholes.
An investigation into the impact of tap hole depth on tree health.
Demonstration on how to test when sap becomes maple syrup. Different tools are discussed.
An increasing number of maple syrup samples containing floating masses or surface mold have arrived at the University of Maine Cooperative Extension. Conventional practices have been to discard obvious mold growths, reboil and consume the syrup. This practice may be risky, especially with the increasing number of food borne illness outbreaks with other food products.
