QUANTIFYING NITROGEN FATE IN KARST AGROECOSYSTEM STREAMS OF CENTRAL KENTUCKY NUMERICAL MODELING AND INSIGHT FROM HIGH-RESOLUTION SENSORS

Nolan Bunnell
In-stream fate of nutrients in karst agroecosystems remains poorly understood, despite the known impact of karst on water resources at local to global scales. In the Inner-Bluegrass region of central Kentucky, heterogeneity of karst maturity, flow pathways, and nutrient sources adds to the complexity of quantifying nutrient dynamics, thus requiring novel monitoring and modeling approaches. The significance of these streams is recognized given spring/surface water confluences have been identified as hotspots for biogeochemical transformations. In...
