Effects of Agricultural Geographically Isolated Wetlands on Hydrology and Water Quality in Georgia

Watch a 12-minute conference presentation from the Georgia Water Resources Conference examining the impact of geographically isolated wetlands (GIWs) on water quality and hydrology in the Dougherty Plain region of southwestern Georgia. Learn about ongoing research investigating how these agricultural wetlands store and process nutrients from fertilizers, potentially reducing groundwater pollution. Discover the methodology behind studying nitrogen and phosphorus dynamics in working farm wetlands, including data collection on precipitation, water levels, and hydroperiod patterns. Explore historical changes in sediment and nutrient dynamics through core sampling analysis, and understand how agricultural expansion has affected these important ecological features over the past 50-100 years. Gain insights into potential management practices that could enhance wetland function while maintaining agricultural productivity, supported by engagement with local farming stakeholders and comprehensive data modeling comparing agricultural and forested GIWs.
