Climate Change Across Seasons Experiment (CCASE) at the Hubbard Brook Experimental Forest: Net Nitrogen Mineralization via Buried Bags

Rates of net nitrogen mineralization were measured on all Climate
Change Across Seasons Experiment (CCASE) plots. There are six plots
total (each 11 x 14m). Two are warmed 5 degrees C throughout the
growing season (Plots 3 and 4). Two others are warmed 5 degrees C in
the growing season and have snow removed during winter to induce soil
freezing and then warming cables turn on to create thaws; each soil
freeze/thaw cycle includes 72-hours of soil freezing followed by
72-hours of thaw (Plots 5 and 6). Four kilometers (2.5 mi) of heating
cable are buried in the soil to warm these four plots. Two additional
plots serve as controls for our experiment (Plots 1 and 2). This data
set includes net nitrogen mineralization data collected in the growing
season of 2017.

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.
