Physical and chemical properties of soils on Watershed 5 of Hubbard Brook Experimental Forest, before and after whole-tree harvest

We sampled soils on watershed 5 at the Hubbard Brook Experimental
Forest in 1983, prior to a whole-tree harvest conducted in the winter
of 1983-84. We resampled in 1986, 1991, and 1998. All sampling was
performed using a quantitative soil pit method. Samples of the
combined Oi and Oe horizons; the Oa horizon; 0-10 cm, 10-20 cm, and
>20 cm layers of mineral soil; and the C horizon were collected.
Grab samples of pedogenic mineral horizons were also taken from the
sides of a subset of pits in each year. Here we report soil chemistry,
mass of soil, percent rock, bulk density, and organic matter.

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.
