- Abstract:
- Foliar chemistry data was collected from green canopy leaf samples in summers of 1998-2000, and 2006-2017 annually at the Harvard Forest EMS biometric plots. Green leaf samples were collected by shooting them down from the canopy with a shotgun. Samples were dried at 65 degrees C for 3 days, ground to a fine powder using a ball mill, and analyzed at the Harvard Forest on a Fison Nitrogen Analyzer NA 1500 in for the 1998-2000 samples and on an Elementar Vario Micro CHNS analyzer in for the 2006-2014 samples. Most recent C and N analyses were performed by the Laboratory of Adrien Finzi at Boston University.
