Added /sup 15/N labeled inorganic nitrogen was used to determine the significance of nitrification-denitrification in flooded swamp soil in removing nitrogen. Nitrogen-15 labeled (NH/sub 2/)/sub 2/SO/sub 4/ and KNO/sub 3/ were added to replicated plots in a swamp forest receiving agricultural runoff. Nitrous oxide and N/sub 2/ fluxes were measured and maximum fluxes were estimated at 24g N/m/sup 2/ x yr and 110 g N/m/sup 2/ x yr, respectively. The capacity of the swamp forest to remove large quantities of nitrogen via nitrification-denitrification processes was demonstrated.
