1 CLEANSED Innovative integrated methodology for the use of decontaminated river sediments in plant nursing and road building LIFE12ENV /IT/ ACTIONS B.3 – Demonstration of the use of decontaminated river sediments as a substrate for plant nursing ACTION C.2 – Monitoring and validation of the use of decontaminated sediments for plant nursing Institute of Biometeorology, Firenze April 3, Pisa

2 OBJECTIVE: Test decontaminated sediments as agronomic substrates in plant nursing, to replace the soil when the plant is explanted for sale BACKGROUND: Plant nursing is a productive field activity which demands high quantity of soil. A European estimation calculates that every year plant nursing consumes about 5,2·10 6 m 3 of soil.
