Improving Water Quality with Better Management Practices in Midsouth Cotton

Results from an on-going field study at the Judd Hill Research Farm near Trumann, Arkansas will be summarized in this presentation. Two years of chemical, physical, and toxicological data have been compiled and analyzed from the small plot field study comparing conventional, low till and low till/cover crop systems.  Methodologies include EPA whole effluent toxicity testing, runoff chemical analysis, and the testing of physical parameters.  Grab sample collections were taken in the summers of 2008 and 2009 following rain and irrigation events.  Results show correlation between tillage treatment types and corresponding chemical, physical, and toxicological data.
