Technical Position Paper on Air Injection

The use of air injection technology in the maple industry can be defined as: the forced introduction of air through a series of perforated pipes submerged in the boiling sap in the front and /or back pan of a maple syrup evaporator. Several studies conducted in recent years have investigated aspects of the use of air injection technology in the process of maple syrup production.

Temperature Patterns with an Oil-Fired Evaporator

Knowing the temperature in the evaporator is an essential part to making quality pure maple syrup. This article will discuss observations of temperature in each partition and how the front and back pans temperatures are influenced by the draw off events.

Temperatures in the Sugarbush

One major limitation to the sap-run forecasting ability of many producers is that measurement of air temperature in one location does not capture the wide variation in air temperature throughout the sugarbush; nor does it accurately reflect the temperature of the diverse parts of trees, or of the soil. A study of the range of temperatures in the forest during sugaring time is helpful in understanding some of the influences of weather on sap flow. This article briefly summarizes a large set of data collected over the past years which includes many sugarbush temperatures, and will give a few examples of the sometimes unexpected variation in temperatures which occur during the spring.

Ten Years with the Asian Longhorned Beetle Program in Massachusetts

ItÕs been 10 years since the ALB was first reported in Worcester, Massachusetts, and since then 24,179 ALB-infested trees have been found and removed, including the four trees mentioned. This has dramatically changed the character of the heaviest hit Worcester neighborhoods, Greendale and Burncoat, and resulted in a massive reforestation effort. Those neighborhoods were the center of the infestation and nearly every single host tree, including street trees, were removed in the effort to eradicate this pest. The DCR ALB Reforestation program, Worcester Tree Initiative, the city of Worcester, and the other five municipalities in the regulated area have replanted thousands of trees. Today, those young trees have become established and have started to provide much needed shade and wind breaks.
