is a bioremediation technology in which contaminated sediment is spread on the upper soil zone or in

cells, mixed with
nutrients
and the material is periodically

The improvement of the chemical-nutritional properties (nutrient balance) of the treated sediments indicated the activation of the nutrient cycle and then the recovery of the agronomic fertility.
The stimulation of the biological parameters contributed to create a functional “soil ecosystem“.
The decrease of the heavy metals (20%) and total petroleum hydrocarbons (50-60%) indicated the efficiency of the

Action B3. Demonstration of the use of decontaminated sediments as a substrate for plant nursery
Every time a nursery plant is sold, a portion of valuable, nutrient-rich soil is subtracted from the land
AGRIPORT decontaminated sediments will be used as agronomic substrate for the cultivation of ornamental plants with different saline stress tolerances to prevent the loss of soil and biomass due to plant nursery activities
