Leachate from core experiments on soils from Sleeper River Research Watershed and Hubbard Brook Experimental Forest (HBEF), flushed with solutions of varying composition

These experimental data were generated to evaluate the effects of shifts in precipitation chemistry (i.e., increases and decreases in acid deposition) on the mobilization of soil constituents from forested headwater catchments.The study includes data from sites:

Sleepers River Research Watershed (SRRW) and Hubbard Brook Experimental Forest (HBEF) in HBEF-T (treated), HBEF-HC (hydrological control), and HBEF-BC (biogeochemical control).
We conducted sampling campaigns in Winter, Spring and Fall 2020 in several landscape positions (see read me file). At each location, we sampled to depth of 0 - 10cm. The minimally disturbed cores were transported to the lab and subjected to repeat flushing using solutions with varying compositions (A= high ionic strength, low pH, R= low ionic strength, neutral pH, M= low ionic strength, low pH, see details in the accompanying “read me” document). Leachates were collected and analyzed for pH, DOC, DIC (in some cases), TDN, inorganic nitrogen and and cations.
