Research webinar: Drivers of Change in Denitrification Capacity of Riparian Soils During Spring Snowmelt

Brittany Lancellotti, PhD candidate in the University of Vermont Rubenstein School of Environment and Natural Resources, shares findings from her 2019 spring snowmelt field campaign, which was conducted to investigate how riparian soil denitrification and its controls vary throughout this dynamic period. The project was designed to study physical/chemical and biological (i.e. microbial community) controls on denitrification. To achieve this, an existing riparian soil monitoring network was leveraged to measure physical controls on denitrification, like soil moisture and oxygen content. Additionally, denitrification rates were measured in conjunction with the abundance of denitrifying bacteria to study how the microbial community is impacted by spring snowmelt. The research was funded by the Vermont Water Center and Vermont EPSCoR.
