Many researchers, in addition to many sugarmakers, have observed that there is a great range in the amount of sap produced from individual trees in a forest. Understanding, and perhaps predicting the different performances of the trees in a sugarbush is an aspect of maple physiology that remains fascinating.
How much money should you expect to make selling sap? There are many factors to consider.
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.
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.
Demonstration on how to test when sap becomes maple syrup. Different tools are discussed.
