An investigation into the impact of tap hole depth on tree health.
Tree growth rate can be an important indicator of how well the tree will heal from tapholes.
A summary of the current state of maple production in New England is based on surveys returned from approximately 220 sugarmakers in April, 2011.
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.
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.
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
A guide to tasting maple syrup and checking for off-flavors
Sugar maple (Acer saccharum Marsh.) is a keystone species in the northern hardwood forest, and decline episodes have negatively affected the growth and health of sugar maple in portions of its range over the past 50+ years. Crown health, growth, survival, and flower and seed production of sugar maple were negatively affected by a widespread decline event in the mid-1980s on the unglaciated Allegheny Plateau in northern Pennsylvania. A long-term liming study was initiated in 1985 to evaluate responses to a one-time application of 22.4 MgáhaÐ1 of dolomitic limestone in four northern hardwood stands.
Root pressure occurs when the soil begins to warm, and when snow has melted, and icy water from snow melt has largely drained from the soil, forest soils warm quickly.
