Nitrogen oxides play an important role in tropospheric photochemistry. This paper presents the results from measurement of nitrogen oxides emissions from an intensively managed soil in the coastal plain of North Carolina. The measurement was conducted from July 15 to August 15, 1996 as part of project NOVA. Fluxes of NOx were determined using a dynamic chamber system. Emission rate of nitric oxide (NO) was found to range from 0.06 to 27.8 ng N/m{sub 2}/s. The fluxes were related to soil temperature, water filled pore space, extractable soil nitrogen and other controlling parameters. Intercomparison of dynamic chamber technique with eddy-correlation technique in this experiment indicates that the two are consistent in measuring NO fluxes.
