Though it is not well known, all species of walnut (Juglans spp.) produce a sweet sap that can be boiled down into valuable syrup. There is a well-established resource of black walnut (Juglans nigra) trees throughout eastern North America that could be utilized for syrup production to complement existing sugaring operations.
Knowing how to properly maintain your sugar bush — a maple producer’s most valuable resource — is a critical skill.
There are a number of ways to clean tubing systems to avoid microbial contamination of tapholes and sap.
Results from research into the impact of tap hole depth on sap yield.
Acid deposition induced losses of calcium (Ca) from northeastern forests have had negative effects on forest health for decades, including the mobilization of potentially phytotoxic aluminum (Al) from soils. To evaluate the impact of changes in Ca and Al availability on sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.) growth and forest composition following a major ice storm in 1998, we measured xylem annual increment, foliar cation concentrations, American beech root sprouting, and tree mortality at the Hubbard Brook Experimental Forest (Thornton, New Hampshire) in control plots and in plots amended with Ca or Al (treated plots) beginning in 1995.
Both the Asian longhorned beetle and the use of imidacloprid to protect sugar maples from this pest pose a threat to maple syrup producers.
Two main issues relate to the sustainability of maple sugaring; tree wounding and sugar removal. In other words, does a tapped maple tree grow more wood than is compartmentalized (functionally “removed by the tree’s normal wound response process) each year and/or does sap collection take more sugar from the tree than can be readily replaced through photosynthesis? These two issues, although separate in some respects, are inextricably intertwined.
3/16″ tubing can provide some yield benefit by creating natural vacuum. That benefit will be directly related to the elevation drop of the lateral line.
Tapping trees has an impact on the value of those trees’ logs for lumber.
The ALB poses a grave threat to maple trees, and to the maple syrup industry.
