Assessment the activity of petropolluted chernozem oxidoreductases at melioration by glaukonite, “dop-uni” and humate potassium

In the conditions of a model laboratory experiment, the introduction of ameliorates to the petrol polluted chernozem and definition the enzymes activity of oxidoreductases class: catalases, peroxidases, polyphenoloxidases is carried out. For melioration used three ameliorates of multidirectional action: glauconite, “Dop-Uni”" and humate potassium. It is established that at petrol polluted chernozem activity of catalase decreased by 14%. The activity of a polyphenoloxidase increased by 10%. The activity of peroxidase authentically did not differ from control. After the introduction only ameliorates to the chernozem it is shown, that activity of catalase was stimulated by a complex of glauconite with “Dop-Uni” and glauconite with a potassium humate. However, after the introduction the ameliorates to the petrol polluted chernozem are shown, the effects both stimulating, and inhibiting activity: stimulation of the activity of catalase and peroxidases at the introduction of humate potassium and “Dop-Uni” complex with a potassium humate for 15 and 13%. Inhibition the activity of catalase and polyphenoloxidases are improved for glauconite with potassium humate. The balanced processes of humification and a mineralisation are noted at the introduction of glauconite and “Dop-Uni” to the petrol polluted chernozem. Tendencies to mineralisation (Kg) at introduction of humate potassium, glauconite with humate potassium, “Dop-Uni” with potassium humate are shown. Humification of the petrol polluted chernozems at introduction of glauconite, “Dop-Uni”, the “Dop-Uni” complex with glauconite is revealed. For diagnostics of the petrol polluted soils after the introduction of ameliorates in them, it is offered to define the activity of catalase and polyphenoloxidases.
