Long-term impact of liming on growth and vigor of northern hardwoods

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.

Maple Syrup Production in a Changing Environment

This report summarizes the results from a survey to document respondent’s experience of changes within maple syrup operations and sugar maple (acer saccharum) ecosystems, including potential changes to regulations, technologies and climate.

Pricing sap

How much money should you expect to make selling sap? There are many factors to consider.

Procedures for Neutralizing Maple Wash Water

Wash waters resulting from the use of cleaning chemicals for reverse osmosis (RO) membranes and evaporator pans are often strongly basic or acid, and should be neutralized before disposal in order to comply with Vermont Department of Environmental Conservation regulations. These instructions for neutralizing maple wash water will allow you to modify your used maple cleaner to a safe pH range.

Results from the 2011 New England tapping survey

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.

Root pressure in trees: a spring phenomenon

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.

The state of the maple industry – 2011

A summary of the current state of maple production in New England is based on surveys returned from approximately 220 sugarmakers in April, 2011.

Why do some maple trees produce more sap?

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.
