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

CHANGES IN BIOLOGICAL PROPERTIES OF ORDINARY BLACK SOILS AT GLEYISATION (MODEL EXPERIMENT)
Description
The article presents the results of laboratory modeling of gleyisation and its effect on the biological properties of soils with stagnant regime in ordinary black soils. Gleyisation is a complex biochemical process that occurs under oxygen reduction conditions. Anaerobic microorganisms, the presence of organic substances, and the constant or prolonged waterlogging of individual horizons or the entire soil profile promote gleyisation. Model experiments revealed that gleyisation increase the total number of bacteria and suppresses number of actinomycetes, micromycetes and growth of fungal mycelium. Gleyisation decreases the activity of oxidoreductases and increases the hydrolases activity. In addition, the second content of humus slightly increases and active acidity (pH) changes to neutral. Accumulation of large amounts of iron oxide (II) in soil is revealed

Description
Rendzina soils are very widespread in the Caucasus. Because of their ecological and genetic characteristics Rendzina has significant buffering capacity to chemical pollution. The object of investigation was calcareous leached soil. Location selection - Azishskaya ridge on the border of the Republic of Adygea and the Krasnodar region. As pollutants, we have selected Zn, Cd, Mo, Se, since soil contamination with these elements in the south of Russia is not uncommon. Contamination of zinc, cadmium, molybdenum and selenium causes deterioration in the biological properties of calcareous soils of the Western Caucasus. We have investigated the toxicity of the elements formed following series due to their influence on Rendzina soils: Zn> Se> Cd> = Mo. The study attempted to analyze the entire range of concentrations of the examined elements in the soil, currently occurring in nature. In most cases, all the investigated substances registered direct correlation between the concentration of the pollutant in the soil and the degree of reduction of biological indicators. The activity of catalase and dehydrogenase cellulolytic ability, plenty of bacteria of the genus Azotobacter, length of roots of radish can be used to monitor, diagnose and regulation of chemical pollution of soil Zn, Cd, Mo, Se

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

DYNAMICS OF RESTORATION OF BIOLOGICAL PROPERTIES OF BLACK SOILS POLLUTED WITH OIL
Description
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

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

ENZYME ACTIVITY OF SEVERAL SOILS OF THE CRIMEA
Description
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

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
