Abstract Sulfur (S) is widely used in agriculture, yet little is known about
its fates within upland watersheds, particularly in combination with
disturbances like wildfire. This dataset includes samples collected
within the Napa River Watershed, California, U.S., where high S
applications to vineyards are common, and ~20% of the watershed burned
in October 2017. The data package includes soil, soil leachate, and
stream chemistry data from sites representing a combination of land
use (vineyard agriculture and grasslands) and burn (burned and
unburned). Bulk soil chemical measurements include total sulfur and
carbon concentrations and sulfur stable isotopes. We then used a
laboratory rainfall experiment to simulate a wet season of
precipitation in order to compare unburned and low severity burned
vineyard and grassland soil leachate chemistry. Soil leachate
measurements include total dissolved sulfur, sulfate, and dissolved
organic carbon concentrations, sulfate-sulfur stable isotopes, and the
specific ultraviolet absorbance at 254 nm (SUVA254), an index strongly
correlated with DOC aromaticity. We compared soil leachate chemistry
to stream samples draining sub-catchments with differing land use and
degrees of burn and severity to understand combined effects at broader
spatial scales. Soil and stream chemistry are provided in separate
data tables, and data from the laboratory rainfall experiment is
included in the leachingexpts (leaching experimental record),
leachingexpchem (chemistry), and leachingexpisotopes (sulfur stable
isotopes) data tables.
