Polyakov V.Yu., Revutskaya I.L. THE ENZYMATIC ACTIVITY OF THE UPPER DIAGNOSTIC HORIZONS OF URBAN ANTHROPOGENIC SOILS OF BIROBIDZHANThe influence of urbanization processes on enzymatic activity of anthropogenic modified soils to date is insufficiently studied problem. Objective: to investigate the enzymatic activity of the upper diagnostic horizons U urbik, AYur, RAT urban anthropogenic soils of Birobidzhan. It is shown that the activity of such enzymes as: catalase, invertase, urease, phosphatase decreases in the next row diagnostic top soil horizons: culturozemš— recreazemš— replantazemš— konstruktzemš— urbanozem. To the established features of urban anthropogenic soils of Birobidzhan include: alkalinity, soils are neutral and slightly alkaline (pH fromš6.6 toš7.4), compared to natural, relatively unmodified, brown forest weakly acidic (pH 5.5–6.5) and soddy-alluvial acidic (pH 4.0–5.5) soil of the city, low cation exchange capacity less than 15šmmol/100šg soil, low humus content less thanš4š%, small and moderate power diagnostic horizons. The enzymatic activity of the upper diagnostic horizons based on the catalase, invertase, urease, phosphatase characterized as low, and the degree of enrichment of poor soil enzymes. Lowest set the activity of enzymes in diagnostic upper horizon of urbik U urbanozem: catalaseš— (1.0š±š0.1)šml O2/min/1šg soil, invertaseš— (1.8š±š0.2)šmg glucose/1šg of soil for 24šhours, ureaseš— (2.0š±š0.2)šmg NH3/10šg of soil for 24šhours, phosphataseš— (0.5š±š0.1)šmg P2O5 /100šg of soil for 1šhour. The most established activity of enzymes in diagnostic upper horizon of AYur culturozem: catalaseš— (2.8š±š0.3)šml O2/min/1šg of soil, invertaseš— (8.2š±š0.7)šmg glucose/1šg of soil for 24šhours, ureaseš— (4.2š±š0.4)šmg NH3/10šg of soil for 24šhours, phosphataseš— (1.3š±š0.2)šmg P2O5 /100šg of soil for 1šhour. The main conclusion: the enzymatic activity of the upper diagnostic horizons U urbik, AYur, RAT urban anthropogenic soils of Birobidzhan on the catalase, invertase, urease, phosphatase can be characterized as low and the degree of enrichment of poor soil enzymes.Key words: activity of enzymes, soil city, soil types.
