In this paper by trifactorial experience was investigated the influence of bacterial inoculum, fertiliser and absorbent on the processes for bioremediation of the soil polluted with crude oil. Test results presented are obtained by analysing the content of THP 60 days after a sample of soil was artificially contaminated with crude oil (THP) to an initial concentration of 3% and 45 days after the treatments. Application of liquid fertiliser containing humic substances and monosaccharides has positive effects on the process of bioremediation of the soil polluted with THP. An important contribution in the process of bioremediation have the absorbents Zeba which has led to significant decreases compared with the control and peat. The contribution of bacterial inoculant in the soil bioremediation processes was significant, leading to a decrease up to 1.64% of THP. Source

Where Zeba absorbent was applied in a 16 kg/ha dose, the most efficient bioremediation alternative proved to be the one using AH-SG1 fertiliser and bacterial inoculant. In this alternative the THP content decreased by 57% in 45 days. Where Zeba absorbent was used in a 32 kg/ha dose, the best results in the bioremediation process were obtained by application of the AH-SG2 fertiliser. In this case the THP level decreased by 58% within 45 days from application of the treatment. Source
