Presentation Title
Groundwater phosphorus dynamics in an agricultural riparian buffer
Abstract
Phosphorus (P) is an essential growth-limiting nutrient in aquatic and terrestrial ecosystems. Soluble reactive phosphorus (SRP) is used in fertilizers. Excess levels of P catalyze the growth of harmful algal blooms and eutrophication of water bodies. Riparian zones, however, are promoted as a buffer for nutrient and pollutant retention and demobilization from adjacent agricultural land before entering waterbodies. The effectiveness of a Riparian Zone as a buffer is influenced by the complex biogeochemical and hydrologic dynamics of the groundwater, soil, and landscape. Due to climate change, Vermont will experience earlier Springs, more precipitation, higher frequency of heavy rainstorms and hotter, drier summers. This research sought to answer the question, how do rain events influence P mobilization and transportation along an agricultural riparian buffer?
