CHANGES IN ORDINARY CARBONATE CHERNOZEM CONDITIONS CONSIDERING MODERN HYDROMORPHISM
Description
There are changes in almost all the properties of chernozems under locally overmoistening. In general, changes in the properties and conditions of chernozems under the development of local wetlands went in a particular way, regardless of the peculiarities of soil formation factors and causes waterlogging. The most noticeable change is the transformation of physical properties of soil and organic matter status. According to our research, more quickly and clearly excessive moisture causes a change in the physical properties of the soil. There are changes of the structural state, bulk density and amount of water-stable aggregates. The significant change is the transformation of soil organic matter. There is increasing of total humus content. In a group composition, the fraction of humic and fulvic acids increases the share. The humus profile is stretched. In the majority of cases in investigated soils was diagnosed secondary salinization. The periodic waterlogging of the soil also contributes to the change in the amount of soil carbonates and their distribution in the profile. Chernozems gradually lose calcium, the main structurant and humates maker. Among the most studied soil of Zernogradsky region in the cationic part of the prevailing spot goes sodium. In addition, the narrowing ratio of calcium to magnesium was observed. That is the hallmark of the aqueous extract of locally overmoistening soils

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
Description
We 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

USAGE OF THE BACTERIAL PREPARATION “DESTROIL” FOR DESTRUCTION OIL POLLUTION IN FRESH WATER
Description
The researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined

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

Description
In article the problem of environmental pollution by veterinary antibiotics and acquisitions of resistance of pathogenic microorganisms to them is considered. In the conditions of field experiment resistance of chernozem microorganisms to pollution oxytetracycline and tylosin is studied

BLACK SOIL RESISTANCE TO COMBINED OIL AND ELECTROMAGNETIC POLLUTION
Description
This 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
