The availability of labile organic C for microbial metabolic processes could be an important factor regulating N 2O emissions from tropical soils. We explored the effects of labile C on the emissions of N 2O from a forest soil in the State of Rondônia in the southwestern quadrant of the Brazilian Amazon. We measured emissions of N 2O from a forest soil after amendments with solutions containing glucose, water only or NO 3 ?. Addition of glucose to the forest soil resulted in very large increases in N 2O emissions whereas the water only and NO 3 ? additions did not. These results suggest a strong C limitation on N 2O production in this forest soil in the southwestern Amazon. [ABSTRACT FROM AUTHOR] |
