Nitrous oxide emission from croplands: biogeochemical drivers, nitrification inhibitors, policy implications, and future directions

Abstract Nitrous oxide (N 2 O) emissions from croplands are a distinct environmental challenge because N 2 O is both a potent greenhouse gas and a major contributor to stratospheric ozone depletion. Emissions arise largely from agricultural nitrogen (N) inputs and microbially med...
