| Tartalmi kivonat: | The phytoremediation of lands polluted with oil products are generally applied in situ as a nondestructive technique. The process of phytoremediation participates in improving the agronomic characteristics of degraded soils. The content of petroleum products in the studied soils ranged between 70.45-120.32g·kg-1 D.M. The experimental study block consisted of in- situ variants located on land polluted by crude oil. The experimental variants were: variants of polluted soil unfertilized / fertilized with 50 t ·ha-1 sewage sludge. In addition, for the variants fertilized with sewage sludge an extra 50 t·ha-1 fly ash originating from power plants was used. From the mixture of meadow plants used for the phytoremediation, the species Lolium spp. and Medicago spp. formed a coating plant layer on the variant fertilized with a mix of sewage sludge with fly ash, which covered up to 90% of the sown area. Effectiveness of the reduction of petroleum products in the soil was over 48% in three months time. The phytoremediation can be promoted with good results for the recovery of oil polluted soils with the use of treatments with sewage sludge and fly ash. |
