Dr. Kate Cassity-Duffey is Assistant Professor specializing in organic production at UGA. Following her Ph.D., Kate worked as a post-doctoral researcher in the UGA Department of Crop and Soil Sciences. She conducted both field and laboratory research focused on nitrogen mineralization and volatilization from organic fertilizers and poultry liter. She self-funded a post-doctoral research project that led to the development of an online calculator that farmers can use to determine nitrogen availability for plants from applied organic fertilizers and poultry liter (https://aesl.ces.uga.edu/calculators/nitrogen/).
