In the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
Negative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely
Significant changes in mountain ecosystems occur after deforestation on limestone massifs of the Western Caucasus. Tall-mountain-meadow vegetation with a large variety of species formed at low and medium soil disturbance 3 years after logging. Physical and biological properties of calcareous soils also vary greatly. The values of biological activity decrease at the maximum load is more than 10 times. Biological activity is increased by 20-50% or more cutting stations with low disorders. Biological properties of soils (especially the enzymatic activity) are very sensitive indicators of changes that have occurred as a result of logging. Changes in the activity of soil hydrolases different from changing oxidase activity at different times after logging
EFFECT OF DEFORESTATION ON THE BIOLOGICAL PROPERTIES OF MOUNTAIN SOIL OF WESTERN CAUCASUS
The number of microarthropods in the black soil de-creased with an increase in the number of oil. The same pattern was observed until a certain concentra-tion of lead in soil (von 250 mg / kg), after which high doses (500 and 1000 mg / kg) was recorded an in-crease in the number of microarthropods. Gamasid mites and ticks of akaroid-trombidiform complex have proven more resistant to lead, and armored mites and springtails - to oil, vise versa
The original soils were investigated at the Black Sea coast of Russia. Severe degradation of the soil in a Utrish nation reserve were identified as a result of high recreational pressure. Soils with high recreational load have low humus content (2-3 times) and a lower en-zymatic activity than the control of the soil. Biological parameters can be successfully used for environmental monitoring of soil of Utrish reserve, in contrast to the chemical and physic-chemical properties
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
The article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase,
invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown
soils under vineyards leads to a significant change in their properties and enzymatic activity
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators
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
