Using isotope pool dilution to understand how organic carbon additions affect N₂ O consumption in diverse soils.

ABSTRACT: Nitrous oxide (N₂ O) is a formidable greenhouse gas with a warming potential ~300× greater than CO₂ . However, its emissions to the atmosphere have gone largely unchecked because the microbial and environmental controls governing N₂ O emissions have proven difficult to manage. The microbial process N₂ O consumption is the only know biotic pathway to remove N₂ O from soil pores and therefore reduce N₂ O emissions. Consequently, manipulating soils to increase N₂ O consumption by organic carbon (OC) additions has steadily gained interest. However, the response of N₂ O emissions to different OC additions are inconsistent, and it is unclear if lower N₂ O emissions are due to increased consumption,
