The present study performed the investigation of new environmental friendly methods to remediate polluted soil with crude-oil. The experiment was carried out in greenhouse, in controlled condition using polluted soil and perlite, in different percent. Also, we used five organic fertilizers (Vermiplant, Amalgerol, Poco, Iguana and Formulex). Based on the data obtained under controlled conditions, the best results were obtained in variants where the percentage of perlite used in the soil mix was 25%. The 50% and 75% perlite mix with polluted soil quantities used in the blend did not bring significant differences in plant growth. The research on the influence of remedial measures of the polluted soil on main growing parameters revealed significant differences on physical and chemical properties of the soil, on plant growth, biomass production and plant biochemical composition before and after the treatment. The proposed technology effectively recovered soil properties and plant growth. Microbial populations included 6-15 bacterial strains belonging to Pseudomonas, Bacillaceae and actinomycetes and 5-10 fungal species. Treatments, especially when applied on soil diluted with perlite stimulated species diversity increasing and pathogen inhibition.
