Estimating Pesticide Retention Efficacy for Edge of Field Buffers Using the Riparian Ecosystem Management Model (REMM) in Southern Atlantic Coastal Plain Landscapes [abstract]. American Chemical Society Spring 2010 National Meeting and Exposition, San Francisco, California, 03/21-25/2010. Technical Abstract: Southern Atlantic Coastal Plain croplands are vulnerable to runoff; thus agricultural pesticide use may adversely impact surface water quality. Our research group has collected data over the past 5 years indicating that this is not the case in Little River Experimental Watershed (LREW) located in coastal plain of southern Georgia. This was likely attributable to the extensive riparian forests within the watershed which intercept surface and subsurface runoff and retain pesticides and other contaminants. The Riparian Ecosystem Management Model (REMM) developed and supported by our research group was recently modified to simulate pesticide retention processes. In this presentation we will demonstrate use of the model in simulations of pesticide retention by forested and grassed buffers and to quantitatively assess buffer design parameters. Models inputs are from a 10-year field scale investigation of tillage impact on water quantity and quality during rotational cotton and peanut production.
