Research Update on Birch Sap & Syrup Trials
For the past several years we have been conducting researcg and extension on tapping birch trees for their sap and syrup production. This article presents some of the lessons learned to date on some of the most frequently asked questions about tapping birch trees.
Researchers downplay fall tapping
Three-year study finds little payoff in sap yield for sugarmakers who tap in the fall.
Response of Sugar Maple to Calcium Addition to Northern Hardwood Forest
Watershed budget studies at the Hubbard Brook Experimental Forest (HBEF), New Hampshire, USA, have demonstrated high calcium depletion of soil during the 20th century due, in part, to acid deposition. Over the past 25 years, tree growth (especially for sugar maple) has declined on the experimental watersheds at the HBEF. In October 1999, 0.85 Mg Ca/ha was added to Watershed 1 (W1) at the HBEF in the form of wollastonite (CaSiO3), a treatment that, by summer 2002, had raised the pH in the Oie horizon from 3.8 to 5.0 and, in the Oa horizon, from 3.9 to 4.2. We measured the response of sugar maple to the calcium fertilization treatment on W1.
