The phytostabilization of the slag and fly ash dumps was studied in an experimental block consisting of variants fertilized with different organic fertilizing agents, sewage sludge or biological sludge resulting from a slaughter house in the absence/presence of an organic stimulus. The organic stimulus was used during the sowing stage and subsequently through regular foliar applications on the grown crop. The organic stimulus Biocomplex 900 is based on a marine brown algae extract and comes from SC EKO GEA EAST SRL, Romania. The germination degree of Lolium perenne seeds was studied at the same time with the coverage degree of sown areas during different phenophases. The plant development and the amount of biomass harvested were monitored. The slaughter house sludge used (0.5 kg·m-2) with the addition of Biocomplex 900 organic stimulus determined a rapid vegetation in the fertilized slag and fly ash variant along with green biomass harvests which was 2-3 times higher than in other experimental variants.
