Abstract
A new chamber method and a stripping method were developed for field measurements of the rate of N2O emission from the water surface and for determinations of dissolved N2O in water from agricultural land. These methods were used for the measurement of drainage canal water and flooded water of rice fields during the period of June 1982 to January 1983. The results demonstrate that aquatic systems of agricultural land may provide both source and sink for atmospheric N2O.Keywords
