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

04.00.00 Geological-mineralogical sciences
DescriptionHydrothermal 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

CHANGE OF BIOLOGICAL ACTIVITY OF SOILS OF NORTH CAUCASUS IN RELATION TO CLIMATE
04.00.00 Geological-mineralogical sciences
DescriptionClimatic conditions have considerable impact on biological properties of soils of the South of Russia. From all studied indicators the most dependent on climate there was maintenance of a humus and activity of polyphenoloxidases and peroxidases. Values of the integrated indicator of a biological condition (IIBC) on a profile of soils decrease in process of increase in an amount of precipitation, decrease in temperature, and increase in height of the district in next order: meadow subalpine → brown forest → gray forest → black leached soil → black typical soil → black ordinary soi

ECOSYSTEM DEGRADATION OF THE LIMESTONE MASSIFS OF WESTERN CAUCASUS AFTER DEFORESTATION
DescriptionSignificant 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

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

CHANGES IN BIOLOGICAL ACTIVITY OF BROWN FOREST SOILS UNDER AGRICULTURAL USE
DescriptionAgricultural 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
