Abstract. Among all global ecosystems, tropical savannas are the most severely and extensively affected by anthropogenic burning. Frequency of fire in cerrado, a type of tropical savanna covering 25 % of Brazil, is 2 to 4 years. In 1992 we measured soil fluxes of NO, N20, C~. and C02 from cerrado sites that had been burned within the previous 2 days, 30 days, I year, and from a control site last burned in 1976. NO and N20 fluxes responded dramatically to fire with the highest fluxes observed from newly burned soils after addition of water. Emissions of N-trace gases after burning were of similar magnitude to estimated emissions during combustion. NO fluxes immediately after burning are among the highest observed for any ecosystem studied to...
