Tension-free lysimeters were installed in three soil horizons at 13 locations within Hubbard Brook Experimental Forest Watershed 1, representing the variation in elevation and forest type of the watershed. At each location, the organic horizon and the B horizon were selected for lysimeter placement. Soil solution samples were collected approximately monthly and analyzed for base cations, soluble anions, trace metals, nitrogen and carbon.
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.
