Abstract: The purpose of this paper is to briefly summarize the results of water quality studies related to water table management conducted in North Carolina over the past 15 years. Results of these studies have provided the basis for designating water table management as a Best Management Practice for poorly drained soils; and as such, it qualifies for cost share assistance under the North Carolina Agricultural Cost Share Program. More than 2000 control structures have been installed in North Carolina since 1983 to provide controlled drainage on over 50,000 ha. This paper also describes management guidelines to enhance water quality benefits of water table management.
