MELNHE: Foliar Chemistry 2008-2016 in Bartlett, Hubbard Brook, and Jeffers Brook (12 stands)

We are conducting nutrient manipulations in three study sites in the
White Mountain National Forest in New Hampshire: Bartlett Experimental
Forest, Hubbard Brook Experimental Forest, and Jeffers Brook.

We monitored foliar chemistry in 12 of our stands (excluding C3)
pre-treatment (2008-2010) and post-treatment (2014-2016). In general,
we found that foliar N concentrations were higher with N addition and
foliar P concentrations were higher with P addition. More
interestingly, P addition reduced foliar N concentrations and N
addition reduced foliar P concentrations. Some interactive effects
were observed (i.e. NxP, Species x N, Species x P, Species x N x P).

This dataset contains pre- and post- treatment foliar chemistry data,
and data from the analysis of quality control standard samples.

These data were gathered as part of the Hubbard Brook Ecosystem Study
(HBES). The HBES is a collaborative effort at the Hubbard Brook
Experimental Forest, which is operated and maintained by the USDA
Forest Service, Northern Research Station.
