Recent findings concerning the budget and cycles of nitrous oxide on earth are summarized, and the sources and sinks for N/sub 2/O on land, in the ocean, and in the atmosphere are examined in view of the N/sub 2/O concentration increase of 0.2-0.4 percent per year, observed over the period of 1975-1982. Possible atmospheric and biospheric consequences of the N/sub 2/O concentration increase are evaluated. N/sub 2/O emission values are given for several major ecosystem types, such as forest, desert, cultivated land; values from different sources are compared and discussed. Analysis shows an excess of documented sources over sinks by 0-51 Tg N/sub 2/O-N/yr. 63 references.
