Recommendations for using marine sediment as growing media

To carry out a suitable remediation process through biological technologies such as phytoremediation and landfarming its is necessary deeply characterize the initial sediment, if necessary, improve the physical and chemical sediment properties (e.g. mixing with gravel, compost etc.) to allow the survival and growth of selected plants and carry out periodical sampling campaigns to monitor the development of the processes and eventually make adjustments to the process (e.g. oxygen, water, nutrients and microorganism supply). At the end of the process, if the sediments do not comply with the reference legislation, they can be mixed with other substrates to reach the required properties (e.g. peat, sludge, coconut).
