Influence of biological product’s carriers on the biological properties of oil-contaminated sod-podzolic soil

The article shows the effect of organomineral fertilizers and various disintegrants-carriers oil-oxidizing biological product a new generation on indicators sod-podzolic soil heavily polluted with oil (up to 10%), decomposition rate in it. Sawdust, lowland peat, barley straw, vermiculite, flax shover lignin were studied as carriers bioproduct that showed positive effects during 2019 growing season. Lignin largest number heterotrophs, sawdust – hydrocarbon-oxidizing microorganisms. introduction contributed restoration enzymatic activity contaminated soil. Low-lying peat had greatest this indicator. Improvement properties oil-contaminated by has sharply increased its efficiency biolproduct combination shover, straw reduced content products much possible (by 9.9–10.9 mg/kg or 40.2–44.3%). Organomineral also significantly improved soils residual them 13.0 52.8%.
