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
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
Agricultural use leads to a significant transformation of soils. The first to use the soil for cultivation react most sensitive biological indicators. The purpose of the study - to establish the effect of using the brown forest soils for planting apple orchards for their biological activity, in particular on the humus content, enzyme activity (catalase and dehydrogenase). For the control, we have selected forest area adjacent to arable land. Because of violations of the natural vegetation, there are changes in hydrothermal conditions of the soil. Humidity soil plowed off under forest, while temperatures gets considerably higher. Plowing, compared with the control, revealed significant loss of humus (50%) in the upper most disturbed horizons. In the lower horizons of the values of this index were quite low (1.5%) on all sections of the test. The decline in humus content, as well as overheating and draining soil tillage results in a change of enzymatic activity not only in the surface layers, but also in the whole profile. Due to the movement of the most favorable hydrothermal conditions in the underlying horizons, an increase of enzyme activity over control values in the deeper layers of the soil. The article shows a possibility of the use of biological indicators as indicators of changes in the brown forest soils as a result of agricultural use
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
