Abstract
It is found that the use of peat-based ameliorants, which also contain nitrogen and phosphorus fertilizers, would promote microbial growth in petroleum-contaminated soil, enhancing thereby the extent and rate of petroleum hydrocarbon biodegradation by 1.5-2 times. The extent and rate of petroleum-contaminated soil remediation was investigated using peat-based ameliorants containing various amounts of carbamide and ammonia nitrate fertilizers. It is found that the use of peat-based ameliorant containing carbamide fertilizer provides for a significant enhancement of microbial activity.
