Abstract
Long-term incubations of salt marsh soil systems in the presence of glucose resulted in a decrease in the soils' denitrification potential. Addition of nitrate or the presence of living
Spartina alterniflora
reversed this effect, indicating that
Spartina
, through the establishment of an oxidized rhizosphere where nitrification can occur, enables the denitrifying bacteria to adequately compete with the less energetically efficient components of the anaerobic soil microbial community.
