Summary

​Water quality can be both a regional and local issue in the Lower Mississippi River Basin. Having more locally available information regarding how management can impact water quality will help propel the region into the future as concerns grow regarding input costs and environmental issues related to the hypoxic zone in the northern Gulf of Mexico. This presentation will help consultants, county agents, growers and other practitioners in the southern US cotton growing regions to better understand how management impacts losses of nutrients. Specifically, efforts to better quantify nutrient and sediment loss at multiple scales are described and initial published results are highlighted.
