Associations of calcium and aluminum with the growth and health of sugar maple trees in Vermont

We compared tree growth and crown condition with soil and foliar elemental composition in 14 sugar maple (Acer saccharum Marsh.) stands in VT, USA, to evaluate if deficiencies or imbalances in cation nutrition were associated with growth and health reductions in native stands. The Till Source Model (TSM) was used to select study sites potentially high or low in calcium (Ca) by predicting the relative Ca concentration of soil parent material derived from glacial till. The TSM successfully identified high or low levels of soil Ca (P = 0.031) and foliar Ca (P = 0.011) among stands.

A History of the Gooseneck: The Brower Sap Piping System and the Cary Maple Sugar Company

The initial application of plastic tubing for gathering maple sap in the 1950s was indisputably one of the most significant technological developments of the maple industry in the twentieth century. However, the first viable tubing system was introduced over forty years earlier as a gravity drawn system made completely of metal.

New Tapping Guidelines

Here I explain why maple producers should know the growth rate of trees in addition to diameter to determine the number of tapholes per tree.

Carbohydrate reserves in Acer saccharum trees damaged during the January 1998 ice storm in northern New York

To assess the effect of the ice storm of January 1998 on sugar maple (Acer sacchan~m Marsh.) tree health, starch, and soluble sugars in twigs from two damaged sugarbushes (younger: trees 50-100 years old, and older: trees approximately 200 years old) in northern New York were measured throughout the leafless phase (September 1998 – May 1999). Trees severely damaged by the ice storm exhibited signs of recovery during the first growth season (1998), that is, greater numbers of lateral (epicormic) shoots and increased wood production in the current year growth ring of branches at mid-crown, and high concentrations of starch in the twigs at the time of leaf drop.

Evaluation of Alternative Sap Ladders: Summary of 2002-2003 Research Project

This research project was established in the spring of 2002 to study the technique of lifting sap with simple “sap ladder” tubing structures. It was conducted during the production seasons of 2002 and 2003 in an operational setting at Wheelers Maple Products in Lanark County, Ontario.

Some Background on the Asian Longhorned Beetle

The beetles were first discovered in Brooklyn, New York in 1996 and spread to neighboring Queens, infesting areas in Sunnyside, Woodside, Astoria, Long Island City, Maspeth, Ridgewood and later in Bayside and Flushing. Small infestations were also found in Flushing Meadows Park, Forest Park in Woodhaven and Kew Gardens Hills. New York city has lost over 4,000 trees because infested ones have to be cut down, chipped and burned.

1998 Ice Storm Effects on the Health and Productivity of Sugar Bushes of Eastern Ontario: Part 2

In 1998, fifteen managed sugar bush blocks with 7% to 72% ice-induced crown damage were established in eastern Ontario. All blocks received dolomitic lime (calcium and magnesium) and phosphorous (P) and potassium (K) treatments in June 1999. Initial crown damage, fall root starch, sap production and sweetness were all measured. Syrup production was calculated.

Fertilization of Sugarbushes Part I: Physiological Effects

The goal of this project was to examine the effects of liming and fertilization on tree physiology, growth and sugar production of a moderately fertile maple stand. In this first report, we describe, in general terms, the study area, treatments, and results of liming and fertilization on tree physiology and growth.

Sugar Maple Health and Management

Most of us understand how to tap trees, gather sap and produce maple syrup. Yet, one of the most important and least thought about tasks of a sugar bush owner is maintaining the health of the sugar maples. To do that effectively, the majority of us can greatly benefit from the help of a professional forester.
