Description
We have investigated the influence of nickel oxide in the amount 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of variation magnetic field with induction of 50, 100 and 650 μT power frequency of 50 Hz on the enzyme activity and phytotoxity of the southern chernozem. We have established significant reduction of enzyme activity of catalase and length of roots after the influence of the variation of magnetic fields. Pollution by nickel as an independent factor caused stimulation of enzyme activity of a dehydrogenaze and length of roots of radish. The greatest inhibition of the activity of all indicators was observed at joint influence of magnetic fields and pollution by nickel of concentration of 1 maximum permissible concentration (1 MPC). Enzyme activity of dehydrogenaze was significantly stimulated (p

Description
In the article we have investigated the influence of nickel oxide in the amount of 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of an alternating magnetic field of induction of 50, 100 and 650 µT power frequency of 50 Hz on the biological properties of alkalinity black soil

Description
In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather than a simple summation of the effects of individual pollutants, shown no direct proportion between the power of the microwave radiation and its biological effect in the combined pollution

Description
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear

STABILITY EVALUATION OF SOUTHERN RUSSIA SOILS TO CHEMICAL POLLUTION
DescriptionWe propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article

Description
In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia

Description
The main contribution to the soil biological properties change in the combined pollution with lead and an alternating magnetic field makes lead pollution. Contribution of the interaction of factors of 20-30%. The contribution of the alternating field was insignificant or unreliable. Black soil and brown forest soils are similar in degree of resistance to the combined pollution. Grey sands have less stability

BLACK SOIL RESISTANCE TO COMBINED OIL AND ELECTROMAGNETIC POLLUTION
DescriptionThis article shows how soil contamination with oil leads to a significant decrease in the values of its biological properties. High levels of induction of the alternating magnetic field intensified oil toxic effects
