Delmas (2008), Nitrous oxide emissions from tropical hydroelectric WebEmission of CO 2 changed minor from spring to summer, and greatly decreased in autumn in the first measured year. In the second year, the emission patterns were changed by rates of N added. N additions generally stimulated the emission of N 2 O, while the effects varied in different seasons and years.
