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. CLEANSED (LIFE12 ENV/IT/00652) is developed by a community of research organisations located mainly in Tuscany whose aim is to demonstrate that river sediments can be used as plant growing substrates. Sediments of Navicelli canal, an hydro-way between Pisa and Livorno, have been dredged and subjected to phytoremediation and landfarming to be experimented as amendant in soil for plant nursing. The experimental plan is set at Ce.Spe.Vi. in Pistoia (Italy). Two substrates characterized by different mix of decontaminated sediments and ground soil (Treatment 1=25:75 and Treatment 2=50:50), are compared to control substrate (CTL=0:100). The experimental setting consists in two wooden frames (3 m3) per treatment (6 in total) filled with substrates. An initial soil analysis concerns physical and chemical properties and water retention capacity, while soil moisture and temperature are continuously monitored. Three ornamental species (Photinia x fraseri var. Red Robin, Eleagnus macrophylla L., Viburnum tinus L.) have been planted in the wooden frames and assessed in the following aspects: physiological behavior during the experiment, root development and biomass at the end of the growing season and eventually, they will be evaluated in their aesthetic value. Moreover, soil cohesion in root ball will be assessed when the plants will be extracted in the traditional way for sale. The experimental plan has just started and preliminary results are not ready yet. However we believe that a destination of dredged river sediments alternative to landfill is necessary. Direct benefits are the reduction of management costs and the use of low cost material, otherwise destined to non use, in plant nursing and potentially in urban green lots, beneficing indirectly even the environment.
