The effects of a dry-rewetting event (D/RW) on soil microbial properties and nutrient release by leaching from two soils taken from adjacent grasslands with different histories of management intensity were studied. These were a low-productivity grassland, with no history of fertilizer application and a high-productivity grassland with a history of high fertilizer application, referred to as unimproved and improved grassland, respectively. The use of phospholipid fatty acid analysis (PLFA) revealed that the soil of the unimproved grassland had a significantly greater microbial biomass, and a greater abundance of fungi relative to bacteria than did the improved grassland. Soils from both grasslands were maintained...

These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), organic carbon, and general water quality characteristics in Pinyon Plain Mine containment pond water samples collected in calendar year 2021.

This dataset has been archived; it has been superseded by version 2.0 (September 2022) which can be found at https://doi.org/10.5066/P9OCS8P7. This dataset describes water yields for precipitation, throughfall and stemflow for 22 rain events within the 41-hectare (ha) forested W-9 catchment at Sleepers River, Vermont. Sampling occurred during the summer and fall of 2018. Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) concentrations are reported for each sampled event. The dataset also includes 5-minute catchment normalized runoff and the hourly precipitation record for 2017 and 2018 calendar years. Stream water chemistry for DOC and TDN are also included.

Conclusions: The proportion of wetlands in the watershed at different scales affects dissolved organic carbon (DOC) concentrations in downstream lakes and rivers. Thresholds/Learnings: Synopsis: This study quantifies how the proportion of wetlands in the watershed at different scales affects dissolved organic carbon (DOC) concentrations in downstream lakes and rivers. Whether the watershed influence varies with season or hydrologic type of lake was also examined. The scaling and modelling approach used offered a useful way to examine heterogeneity of land cover types within the watershed and spatial arrangements, while allowing generality of conclusions with a large sample size. Zones of increasing distance from...
