Cellulotic activity of sod-podzolic soils of subtaiga landscapes contaminated by different types of hydrocarbon fuel

The research based on the method of modeling in natural conditions was conducted from 2014 to 2017. Three types of hydrocarbon fuel (gasoline, kerosene and diesel) were spilled into sod-podzotic soils of the chosen site (5 g/kg, 25 g/kg, 500 g/kg). That resulted in various changes of the soil cellulotic activity which were analyzed considering the seasonal dynamic. The changes of the activity are reflected in the diagrams.
