Abstract
Sewage sludge was applied biweekly to the soil surface of a shortSpartina alterniflora marsh in order to evaluate the marsh’s ability to assimilate the sludge nitrogen. After nine months there was a significant decrease of the denitrification potential in the first 15cm of the soil profile. In laboratory experiments the sludge was shown to have an immediate inhibitory effect on potential soil denitrification rates indicating that the decreasedin situ potential was probably a result of direct toxicity of the sludge on this bacterial respiratory process.This publication has 2 references indexed in Scilit:
