- Abstract
The article reports on the use of the Flux-gradient technique to measure the magnitude of trace gas fluxes over an unfertilized agricultural field. Extensive spatial and temporal variability were exhibited by trace gas fluxes that are dependent on factors such as meteorology ambient concentration, and emission source size. In this study, Flux-gradient technique was used to measure ammonia, nitric acid and sulphur dioxide over unfertilized soybean field. It is concluded that in order to more accurately determine stomatal resistance and its influence on fluxes in future studies, quantification of vegetation characteristics would be beneficial.
