Comparison of Digital Refractometers for Use by Maple Producers

The purpose of the present experiment was to test the precision of a variety of digital refractometers available to maple producers. Additionally, the effect of temperature on refractometer accuracy and precision was investigated, in order to assess the reliability of the automatic temperature compensation feature now present in the majority of refractometers.

Could Maple Syrup Help Cut Use of Antibiotics?

Recent findings, published in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.

Evaluation of Sugar Maple Dieback Trends in the Upper Great Lakes Region

Crown dieback and declines in tree health of sugar maple (Acer saccharum) have been reported on various land ownerships in the western Upper Great Lakes region in recent years (MDNR 2009, 2010, 2012). In some areas, the crown dieback has affected high-value crop trees. Historically, sugar maple dieback (fig. 10.1) has been reported more frequently in the eastern part of its range and has not been described on the same scale in the Great Lakes region since the 1950s and 1960s (Bal and others 2015, Millers and others 1989). As a result, fewer studies of canopy health of sugar maple exist in the Midwest than in the Eastern United States.

Everything you need to know about plastic maple syrup containers

Plastic is made from hydrocarbons derived from petroleum or natural gas. The hydrocarbons are formed into chains called polymers or plastic resins. Different combinations of hydrocarbon molecules produce different types of plastic. There are seven different types of plastic resins, each with different features. For example, some are resistant to acids and some to caustics. Others may be able to withstand high and/or low temperatures. Some plastics are rigid and some are flexible. There are impact resistant plastics and those that are not. Certain plastics provide a good moisture and/or gas barrier – several are appropriate for contact with food.

Examining the impact of seed production on sap sugar content

Sap flow is only part of what determines the total amount of syrup made (and how much money ends up in a syrup producer’s pocket). New research suggests sugar makers may be advised to look to their trees’ canopies as well as the weather forecast if they want to predict the tapping season.

Forests of Vermont and New Hampshire 2012

The first full remeasurement of the annual inventory of the forests of Vermont and New Hampshire was completed in 2012 and covers nearly 9.5 million acres of forest land, with an average volume of nearly 2,300 cubic feet per acre. The data in this report are based on visits to 1,100 plots located across Vermont and 1,091 plots located across New Hampshire. Forest land is dominated by the maple/beech/birch forest-type group, which occupies 60 percent of total forest land area.
