Abstract. The paper presents the interplay of the studied factors (absorbents, fertilizers, bacterial inoculum) upon the mobile phosphorus content of a soil polluted with 3% crude oil, 45 days from treatments application or 60 days from the pollution moment. The highest mobile phosphorus values were obtained in the variants fertilized with N200P200K200 mineral fertilizers against the application of 32 kg/ha Zeba absorbent; the values were also high in the variants in which the N200P200K200 mineral fertilizers were applied together with bacterial inoculum. From the applied new fertilizers AH-SG1 (potassium humates containing fertilizer in an NPK-type matrix with micro elements plus 50 g/l glucose) and AH-SG2 (potassium humates containing fertilizer in an NPK-type matrix with micro elements plus 100 g/l glucose) had the best effect on the soil mobile phosphorus level.
