Description
In this article, we have presented a number of modeling experiments to investigate the chemical pollution of brown calcareous soil. It assesses the stability of brown calcareous soil of a nature reserve called Utrish to contamination with heavy metals in biological parameters. Pollution of brown calcareous soil with Cr, Cu, Ni, Pb and oil causes a significant reduction in biological parameters. The degree of reduction depends on the nature of the contaminant and its concentration in the soil. The study showed that the indicators used in the biological condition of the soil, could be recommended for use for diagnosis, monitoring, and regulation of chemical pollution of brown soil. According to the degree of resistance to chemical contamination, the brown soils of Russia form the following series: typical brown - brown carbonate - brown leached

BIO-DIAGNOSTICS OF RESISTANCE OF GREY FOREST SOILS OF ADYGEA TO POLLUTION WITH Zn, Cd, Mo, Se
Description
The essential part of a soil cover of the Republic of Adygea is occupied by gray forest soils. Thus they still remain a little studied, including concerning their resistance to chemical pollution. Contamination of gray forest soils of Adygea with Zn, Cd, Mo, Se causes deterioration of their biological properties. In most cases, the degree of reduction of the values of biological indicators is directly dependent on the concentration of pollutant in the soil. According to the degree of toxicity to the biological properties of the investigated elements form the following sequence: Se > Zn > = Cd > Mo. Biological parameters investigated in research (activity of catalase and dehydrogenase, cellulolytic ability, abundance of bacteria of the genus Azotobacter, radish root length) may be used for purposes of monitoring, diagnosis and regulation of chemical pollution of gray forest soils Zn, Cd, Mo, Se

BIOLOGICAL FEATURES OF THE BLACK SOIL DEPOSITS IN THE BOTANICAL GARDEN OF SFU
Description
We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits

BIOLOGICAL PROPERTIES OF BLACK LEACHED SOILS OF THE ROSTOV REGION
06.00.00 Agricultural sciences
Description
The regularity that increases biological and enzymatic activity with increasing the age of the deposits of 10 to 82 years has been shown. The indicator of recovery of black leached soil steppes can be presented as invert-ase activity and humus content, as well as reducing the density of the soil. Integrated indicator of the biological properties decreases with decreasing age deposits: 82 years (100%) - 26 years (84%) - 16 and 10 years (74%) - arable land (64%)

Description
Large agricultural load on the steppe landscapes leads to the transformation of ecosystems and effect on all their components. Transformation of lands into laylands leads to a gradual restoration of anthropogenically disturbed steppe ecosystems. Studies that focus on the research of comprehensive processes in the territory of laylands are extremely relevant today. Herpetobiont fauna is one of the important characteristics of ecology and biology of soils. Herpetobiont Coleoptera can serve as indicators in the study of processes occurring in postagrogenic soils.The article presents the results of the study of changes in mesofauna, composition and structure of complexes of the gerpetobiont Coleoptera of ordinary black soils in natural succession series of different-age laylands. We also evaluated the degree of faunistic similarity of plots of laylands and allocated dominant species. Carabidae and Tenebrionidae are the basis of complex Coleoptera in the investigated laylands. The article shows that such indicators as the number of individuals, species, families of beetles and their dynamic density are depended on the age of the layland. In addition, the indices of biodiversity (Margalef and Shannon) and dominance (Simpson) are also connected with the age of plots of laylands

Description
Hydrothermal conditions have a significant effect on catalase activity of soils of the South of Russia. The linear dependence of catalase activity in the upper horizons soils from average annual rainfall, aridity index of de Martonne and the coefficient of moisture of Mezentseva. In terms of catalase activity of the entire humus profile we revealed that the maximum activity has leached black soil, located in the medial climate conditions of the South of Russia

Description
We studied the effects of heavy metal pollution on soil phytotoxicity cities of the Rostov region. The research objects were the soils of urbolandscape towns: Taganrog, Novocherkassk, Gukovo, Shakhty, Azov. The study of the soil pollution with heavy metals was recorded in Gukovo, Shakhty, Taganrog. The degree of pollution of the studied cities form the following row: Gukovo > Shakhty > Taganrog > basics > Novocherkassk. The research was carried out in 2011-2015 at the Department of ecology and environmental Sciences of southern Federal University. In most cases, there was a direct correlation between pollutant concentration and the degree of deterioration of the studied soil properties. Used biological indicators are informative for monitoring of urban soils polluted with heavy metal. The degree of informativity of biological indicators form the following row: root length > germination >length of shoots. The results of the study can be used for monitoring and diagnosing the condition of contaminated soils, in the assessment of environmental impact, risk assessment of natural and synthetic disasters, the development of regional standards on the content of heavy metals in soil and in other environmental and industrial activities

Description
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

EFFECT OF RECREATIONAL LOAD ON SOIL RESERVE “UTRISH”
04.00.00 Geological-mineralogical sciences
Description
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
