Recent findings concerning the budget and cycles of nitrous oxide on earth are summarized, and the sources and sinks for N2O on land, in the ocean, and in the atmosphere are examined in view of the N2O concentration increase of 0.2-0.4 percent per year, observed over the period of 1975-1982. Possible atmospheric and biospheric consequences of the N2O concentration increase are evaluated. N2O 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 N2O-N/yr.
