Synopsis: Agricultural systems are responsible for a significant portion of methane (CH4), and nitrous oxide (N2O) emissions in the United States. This research investigates the spatial distribution of denitrification markers (denitrification enzyme activity, soil N2O emissions, soil N2 emissions, and nosZ abundance), and how varying management practices influence soil N2O, CH4, and CO2 emissions within cropping systems. Results from this work provide insight into soil biogeochemical processes in cropping systems and can potentially influence management decisions.

Dr. Johnson is an agronomist whose work focuses on greenhouse gas emissions within agricultural systems, including methane and nitrous oxide. His research talk will take place on Monday, May 1st at 3:30 PM in Paige Laboratory Room 202.


Dr. Johnson is currently a postdoc, and his work focuses on nitrogen and greenhouse gas emissions within agronomic systems. 

Dr. Johnson is a Bridge Scholar.


All Seminar Sessions are from 3:30pm to 4:30pm.
