Zhu (Iowa State U): Drainage of wetland prairie in Iowa led to ag land. How does drainage system (intensity & spacing) affect N2O in context of ag systems. Field flux measurements and depth flux measurements => fertilizer pulses N2O flux MUCH (x10+) bigger then freeze/thaw pulse + no drain increases N2O emissions. N2O in subsoil is inverse from surface emissions ? possibly due to microbial community anoxic conditions. Drainage reduces N2O emissions by 8 kg ha-1 yr-1.
