- Abstract
- River sediment is integral and dynamic part of our river basins but where human activities
interfere with sediment quantity or quality, sediment management becomes necessary. Dredging
and especially stocking sediments is highly expensive, therefore it would be valuable to find
ways to make them a reusable product instead of throwing to landfill.
On the other side, there are productive field activities demanding high quantity of soil, such as
plant nursing. A European estimation calculates that every year plant nursing consumes about
5,2·106 m3 of soil. So, the purpose of CLEANSED project (LIFE12 ENV/IT/00652) is to use
river sediments as plant growing substrates after being decontaminated through phyto
remediation technologies.
CLEANSED is developed by a community of research organisations located mainly in Tuscany
and focuses on the sediments of Navicelli canal, an hydro-way between Pisa and Livorno. After
dredging, sediments are stocked in basins and subjected to phytoremediation or landfarming.
After phytoremediation process, the sediments are experimented as amendant in soil used for
plant nursing: the substrate has to guarantee root development but also soil cohesion of root balls
when the plants are extracted for sale.
Therefore, the experimental plan aims to test substrates with different percentage of sediments
and soil in order to identify the mixture which guarantees the best plant quality. Three
ornamental species among bushes and trees, will be planted and physical and chemical
properties of the substrates will be compared. . Physiological behavior and stress signals will be
monitored during the growing season while plant growth will be measured at the end of the
experiment. Eventually, root ball cohesion and the aesthetic appearance (branching, leafage
colour) will be evaluated as test for sale. In conclusion, the project team aims to demonstrate
that phytoremediation technologies are effective methods to transform river sediment (literal)
