Abstract

The algorithm of determining the content of oil products safe for plants and microorganisms in soil subjected to recultivation is presented. The algorithm includes laboratory modeling of recultivation of soil samples containing different amounts of oil products, determination of biological parameters providing an integral characterization of the soil state in these samples, and analysis of the results on the basis of the statistics of chance ratio, which allows one to determine the content of oil products starting from which the state of oil-polluted soil reliably has no differences from the reference.
