Leachate from core experiments on soils from Sleeper River Research Watershed and Susquehanna Shale Hills CZO, 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 two sites:

SRRW – Sleepers River Research Watershed, located in Danville, Vermont
SSHCZO - Susquehanna Shale Hills Critical Zone Observatory
We conducted sampling campaigns in Spring and Fall 2019 in swales (low lying landscape positions) and planar hillslopes. At each location, we sampled 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, C= 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.
