{"Abstract":["This data set includes chemistry of O-horizons ("forest floor") and the 0-10 cm \nmineral soil layer in Watershed 1 at Hubbard Book. Calcium in the form of wollastonite \n(CaSiO3) was added to Watershed 1 in October 1999. The application rate was 1028 kg \nCa per ha, and the application was relatively uniform across the watershed. Pre-treatment \nforest floor surveys were completed in 1996 and 1998. The first post-treatment forest \nfloor survey was completed in 2000. This data set includes mass and thickness data for \nthe sampled layers. Chemical data include concentrations and pools of organic matter, \nC, N, Ca, Mg, K, P, Mn, Fe, Al, Cu, Pb, and Zn. Soil pH and exchangeable Al, Ca, Mg, K, \nand H are also included. Sampling is intended to continue at 4 or 5 year intervals.\n These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). \nThe HBES is a collaborative effort at the Hubbard Brook Experimental Forest, \nwhich is operated and maintained by the USDA Forest Service, Northern Research Station."]}

Hubbard Brook Experimental Forest: Relations of the O-horizon with canopy tree species and hydropedologic soil types, 2021
As the interface between plants and soil, the organic horizon is the foundation of forest ecosystems. Two potential predictors of O-layer properties, vegetation and mineral soil type, are difficult to separate because they typically covary. We conducted a factorial study involving four canopy tree species and two soil types with distinctly different hydrology and topographic position to parse patterns in chemistry and microbiota of the O-layer in a north-temperate deciduous forest. 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.

Soil pits and horizons were described and sampled as part of the Lateral Weathering project within Watershed 3, Hubbard Brook Experimental Forest, Woodstock, NH, USA from 2018-2020. Soil pits were dug and described using NRCS methods. When possible, physical samples were archived in the Hubbard Brook Sample Archive. 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.more » « less

Tension-free lysimeters were installed in three soil horizons at three locations adjacent to Hubbard Brook Experiment Forest Watershed 6. At each location lysimeters were placed beneath the Oa horizon and within the upper and lower B horizon. Soil solution samples were collected approximately monthly and analyzed for pH, acid neutralizing capacity (ANC), base cations, soluble anions, trace metals, nitrogen and carbon. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES).
