Maple producers sometimes have a difficult time locating areas on the tree that will produce unstained wood and good sap yields. This video suggests approaches maple producers using vacuum can take to counter this problem.
Great video. Because of your research, we started tapping below our laterals 3 years ago and it has made a world of difference. Better tap holes, and better yields because of it. Thank you for the work you are doing to further the maple industry.
you can use a VAWT wind turbine attached to compressor and extract a lower quantity of sap, just decoupling the pump system with a sap level arduino alarm to your phone, so you can extract from lots of trees with no cost and little damage to the trees
Watching from australia! I was wondering if a maple tree can survive here? Cause your videos are very informative and inspire me to add a maple tree to my garden. Cheers
Tapping into new wood is a good plan but even with vacuum I would never tap below the lateral. It just sounds like trouble to me, you want the sap to go downhill even when your vacuum pump loses power or breaks down
The relationship between sap yield and vacuum is linear. The more vacuum you pull the more sap you get. Turns out to be about a 5-7% increase in sap yield for each 1" Hg vacuum you pull, so the higher the better. It depends upon what your pump is capable of, but typically we consider high vacuum to be better than 25" Hg.

Hello Chris. This series of brief videos in this playlist is aimed at teaching maple producers high yield sap collection techniques, and thus assumes the viewer has some basic familiarity with maple equipment and techniques. It is impossible to introduce all of the equipment, techniques and terminology and to still keep the videos brief and focused on just a couple of points. If you wish to learn more about maple sap collection tubing systems, I would direct your attention to this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c6lpMgsfF-c.html Thank you for your interest.
