Abstract

Denitrification is fundamentally important in the global biogeochemical N cycle because it is the major route by which inorganic oxidized N compounds in the soil return to the atmospheric N pool. The literature addressing denitrification is legion, consequently, this review only briefly overviews the background of denitrification studies and the cellular biology of denitrification; its main focus is on the environmental factors controlling denitrification in the soil environment, and the detection of denitrification in the soil microbial community. It helps us re-evaluate what we understand about the biology and process of denitrification to better manage N resources in soil ecosystems. There is great uncertainty about the role denitrification plays in ameliorating or abetting NO and N2O flux, and the role that human management of the soil environment has played through fertilization, wetland drainage and wetland creation, and soil amendment with organic and inorganic wastes.
