A one-year study in a typical agricultural region of Southeast China was conducted to determine atmospheric nitrogen fluxes of typical N compounds and contribution of two sources (wet and dry deposition) to N deposition. The results show that ammonia was the major component within the samples, accounting for 55-60% of the dissolved inorganic nitrogen concentrations. For one year in 2004, the total atmospheric N deposition was 28.8 kg N ha^-1, with wet deposition accounting for 93.8% of the total deposition. Ammonia was the predominate contributor, accounting for 64.4% of the total deposition. Therefore, atmospheric N deposition should be considered when water eutrophication and critical loads of atmospheric deposition on agricultural system are estimated.
