dc.description.abstract | The main objective of this research was to estimate the total mass of nitrogen discharged from various sources in Korea using the mass balance approach. Three different nitrogen mass balances were presented: (1) agricultural activities including raising crops and animal husbandry; (2) domestic activities, and (3) activities in forest and urban areas. These nitrogen balances were combined to estimate riverine discharge of nitrogen to the ocean in national scale. Nitrogen inputs include atmospheric deposition, biological nitrogen fixation, application of inorganic fertilizers/manures, animal feed/imported foodstuffs, and meat/fish. Nitrogen outputs include ammonia volatilization, denitrification, human/animal waste generation, crop/meat production, and riverine discharge to the ocean. The estimated total nitrogen input in Korea was 1,194.5 x 10(3) tons N/year. Nitrogen discharged into rivers was estimated as 408-422 x 10(3) tons N/year, of which 66-71% was diffuse in origin. The estimated diffuse discharges for land uses were estimated as 82 x 10(3) tons N/year from agricultural areas, 7 x 10(3) tons N/year from forestry and 75 x 10(3) tons N/year from urban and industrial areas. | - |
