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 5,2·106 m3 of soil.
