Selecting and applying appropriate strategies for in situ phytoremediation of the oil soil polluted with 95.5 ± 25.0 g TPH kg–1 d.m., leads to their rehabilitation by planting and maintaining crops of pastures with grasses and leguminous species. The oil polluted soil addition of 50 t ha–1 fertiliser with nitrogen content, like stabilised sewage sludge, mixed with adsorbents material, i.e. fl ash waste derived from power plants that uses fossil fuel or volcanic indigenous tuff has led to installation of abundance and healthy culture. The areas were covered by grasses and leguminous species was up to 90% of sown areas. Resulting harvest from treated variants with fertiliser mixed with adsorbents material were 2–3 times higher versus harvests obtained from fertilised variants in the absence of fly ash on indigenous volcanic tuff. The harvest characteristics obtained on oil polluted soil fertilised with sewage sludge mixed with fly ash or volcanic tuff were correlated with national forage norms.en-USTotal petroleum hydrocarbonsFertiliserIn situ phytoremediationPastureArticle
