New York Maple Research Evaluates Re-Tapping Potential
USAgNet - 04/03/2020
Maple production research by the farmer-driven Northern New York Agricultural Development Program (NNYADP) is helping New York maple producers evaluate and add opportunities to increase sap and syrup production. The Northern New York maple
industry has grown from a $3.25 million annual industry in 2008 to an estimated $10-plus million industry with room yet to grow.
With an NNYADP grant, Adam D. Wild, director of the Cornell University Uihlein Maple Research Forest, Lake Placid, is conducting trials to test the feasibility of re-tapping maple trees to increase single-season sap production. Data at the end of the current
maple season will provide further answers.
"Recent projects here that looked at the optimum timing for tapping maple trees indicated that early tapping to capture early season sap runs and re-tapping later in the season could have potential to increase syrup production yields by at least 20 percent or
produce a $6 per tap profit increase," says Wild.
"The data from the most recently-completed trial were not as expected, most likely as a result of the northern New York weather and short maple season in 2019. Although one could say it was an ideal season for consistent sap flow, the flow did not fully start
until March 15 and quickly ended April 19," Wild explains.
Four re-tapping treatments were tested in 2019 with no statistically significant differences observed with any of the methods. The best result was seen with the trees tapped March 1 and not re-tapped. Trees that had a second dropline and spout added near the
end of the season were second best with an 18.5 percent increase in production over trees tapped at the same time but not re-tapped.
