Research Abstract |
<Emission> The amount of ammonia emission from agriculture was estimated by each sector and shown in km-mesh map. Ammonia flux on arable, paddy and grassland was observed. <Actual situation> Atmospheric ammonia and ammonium concentration was monitored at 27 sites in Japan. Dry and wet deposition was measured in an intensive dairy region in Tochigi prefecture, and showed N flow through ammonia in the region. <Influence> By analyzing river water N concentration and N input in the Shibetsu basin in Hokkaido, it was suggested that a part of N imported into the basin exported through river N but remained N oxidized to NO_3, which accelerate the increasing HCO_3 concentration in the river through denitrification process.
