BIOLOGICAL FEATURES OF THE BLACK SOIL DEPOSITS IN THE BOTANICAL GARDEN OF SFU

abstract 1041410043 issue 104 pp. 595 – 606 30.12.2014 ru 1198
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

CHANGES IN BIOLOGICAL ACTIVITY OF BROWN FOREST SOILS UNDER AGRICULTURAL USE

abstract 1121508053 issue 112 pp. 714 – 724 30.10.2015 ru 1241
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

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

abstract 1041410040 issue 104 pp. 562 – 571 30.12.2014 ru 1085
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

THE INFLUENCE OF HYDROTHERMAL CONDITIONS ON THE CATALASE ACTIVITY OF THE ZONAL SOILS OF THE SOUTH OF RUSSIA

abstract 1041410084 issue 104 pp. 1129 – 1142 30.12.2014 ru 2059
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

THE INFLUENCE OF THE AGE OF THE LAYLANDS ON HERPETOBIONT FAUNA OF POSTAGROGENIC CHERNOZEMS OF THE ROSTOV REGION

abstract 1121508051 issue 112 pp. 692 – 702 30.10.2015 ru 1290
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
