The anaerobic uptake of [ 14 C]glucose was used as an index of potential microbial activity in the soils of a Spartina alterniflora salt marsh. The turnover times of glucose were consistently faster in the soils where tall S. alterniflora grew along a creekbank than in the high marsh soils where S. alterniflora productivity was lower; this difference was magnified with increased depth. The distribution of label, followed through CO 2 , particulate, and ether‐soluble fractions indicated rapid recycling in the soil of the tall S. alterniflora marsh. In an experiment designed to assess the effects of tidal inundation on the activity of the microbial community in the tall S. alterniflora marsh soils, no consistent changes in glucose uptake or ATP concentration were evident after 2 months of restricting water movement. No direct link of tidal inundation with the microbial community was observed.
