Bacterial denitrification drives elevated N

O emissions in arid southern California drylands

Abstract:Soils are the largest source of atmospheric nitrous oxide (N
2
O), a powerful greenhouse gas. Dry soils rarely harbor anoxic conditions to favor denitrification, the predominant N

O-producing process, yet, among the largest N
2
O emissions have been measured after wetting summer-dry desert soils, raising the question: Can denitrifiers endure extreme drought and produce N

O immediately after rainfall? Using isoto… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
