Abstract

Denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island were measured. Measured rates were compared with rates of NO3- removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NO3- and a bromide tracer to groundwater in the same riparian forest. Limiting factors for denitrification were assessed, and microbial and root biomass and potential net N mineralization and nitrification were compared in aquifer material exposed to the 10 mo of NO3- dosing and unexposed control material.
