Evaluation of wireless system to monitor vacuum in subing systems.
The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.
In order to survive, trees must overcome their injuries. But technically they donÕt heal their wounds, at least not the way that human and animal bodies repair, restore, or replace damaged cells or tissue. Trees are built in layers of cells that are bound by rigid walls in a modular, compartmented way. This structure dictates their wound response.
Recent technological advancements have increased the amount of sugar-enriched sap that can be extracted from sugar maple (Acer saccharum). This pilot study quantified overall sugar removal and the impacts of vacuum (60 cm Hg) and gravity sap extraction on residual nonstructural carbohydrate (NSC) concentrations and on stem and twig growth.
Average annual percentage rates of change (APR) in maple syrup prices (average gallon equivalent price in the United States) in seven northeastern United States and their aggregated region were determined for the years 1916 to 2012. The price trend lines were then compared on state-by-state and region-by-state basis.
Over the past six years, my laboratory, and others, have been conducting research focused on identifying bioactive plant compounds (known as phytochemicals or phytonutrients) and evaluating the biological effects of maple syrup, maple water (i.e. maple sap), and maple plant parts and their derived extracts.
We found significant populations of snake worms devouring the organic matter, causing soil conditions that discouraged growth of understory native plant species. We are looking at their distribution in maple stands throughout the region relative to forest management practices, and assessing their impact on understory diversity, maple regeneration and various soil characteristics.
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.
