Bio: Dr. Sarrantonio received her B.S. degree in 1978 from the College of Mt. Saint Vincent.  She received her M.S. degree in 1981 and Ph.D. in 1987 from Cornell University.  She joined the faculty in 1999 after working for 7 years in international agricultural development and 5 years teaching sustainable agriculture in Pennsylvania.  She is currently an Associate Professor of Sustainable Agriculture.

Teaching:  NFA117 Issues and Opportunities; PSE101 Cropping Systems; PSE320 Soil Organic Matter Management;  PSE396 Field Experience; PSE430 Environmental Horticulture

Current Research:  My research is focused on short-term nitrogen cycling and long-term soil quality changes as affected by crop rotations, particularly those including cover crops, as well as the efficacy of commercially available organic N fertilizers.  Current research projects look at the timing of N availability with the application of a range of different sources of N approved for organic crop production in vegetable crops.  I am looking at the relative rate of N availability as it is affected by the growing  season temperature and light changes from early spring though late summer, as well as in greenhouse production in the fall and spring seasons.
