Kim Zitnick, an NDSU graduate student pursuing a master’s degree in soil science, and Nancy Shappell, U.S. Department of Agriculture – Agricultural Research Service research physiologist and biological sciences adjunct faculty member, will present a seminar on Thursday, Jan. 21, at 3 p.m. at the Biosciences Research Laboratory, 1605 Albrecht Blvd.
Zitnick will present "Transport of 17 ß-estradiol in Liquid Swine Manure." Her work is funded by a National Science Foundation research grant and provides a framework for understanding how estrogens interact with soil and manure. Understanding these processes will aid in design of effective manure handling practices to ensure environmental protection from endocrine disruptors.
Shappell will present "Dairy CAFOs, Best Management Practices and Estrogenic Activity in Surface Waters – Good News for Agriculture, Environmentalists and Consumers." Her work has evaluated the estrogenic activity of surface waters associated with a large dairy confinement operation using best management practices.
