The paper presents results of research evaluating the influence of the phytoremediation
of soil contaminated with diesel fuel on the numbers of the three main taxonomic groups of soil
microflora. Two species of plants have been used in studies: red fescue (Festuca rubra)
varieties Areta and red clover (Trifolium pratense) varieties Nike. Quite variable factors in the
experiment was also the soil type and incubation time. It was found that microorganisms
showed different sensitivity in the presence of diesel fuel in the soil and remediation treatments.
Stimulatory effect of phytoremediation was reported There has been stimulating effect
phytoremediation for bacteria and actinomycetes in sandy soil and unclear reaction for fungi,
irrespective of plant species and soil type used in the experiment.
