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.

Should Lateral Lines Be Vented?

A great deal has changed since the 1960s and 1970s in terms of maple production and recommended practices, especially given the introduction of the new polyethylene tubing formulations and new types of spouts. Consequently, we are occasionally asked whether lateral lines in gravity tubing installations should be vented. As a result of these questions, we compared sap yield from standard non vented (closed) 5/16″ lateral lines alongside a vented 5/16″ installation under gravity conditions.

How sugarmaples regenerate themselves to produce successive crops.

Sugar Maple Sap Yields Using One or Two Tapholes Per Tree

Studies currently underway at the University of Vermont Proctor Maple Research Center (PMRC) are examining the effects of accumulating internal taphole damage on the ability to support future tapping, as well as related subjects such as the effects high vacuum sap extraction might have on tree growth, all with the goal of developing new sustainable tapping guidelines. However, along with focusing on the possible negative effects of tapping and sap extraction, it is important to examine how certain practices might lead to greater sap yields.

Sugarbush roots

The root systems of our trees are rather mysterious, and somewhat fragile. It pays to take precautions to protect the part of the tree that is not visible, just as we protect the rest of the tree that we can see.

Sugaring in the Fall

Sap can be collected and syrup produced in the fall, but sugar content is low and the practice raises additional challenges for the spring crop.

Sugarmakers as teachers

One way that maple producers can gain useful information is by attending the education programs put on by Extension in conjuction with county and state maple organizations, where speakers include not just university and government specialists, but also sugarmakers who share their knowledge and experience.
