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
In this study, we have investigated the migration of
paclobutrazol in the sod-podzolics soils. The migration
of pesticide was restricted with 5 cm in the field study.
Paclobutrazol was found in 11 days after application in
the lysimeter’s water samples, though the pesticide is
moderately mobile. The lysimeter study showed that
the risk of ground water contamination would exist if
application of paclobutrazol was on the sod-podzolics
medium loamy soils. The modeling by PEARL 4.4.4
and MACRO 5.2 simulated the migration of
paclobutrazol until 18 cm in the soil. MACRO was
able to predict the leaching of pesticide. The simulated
paclobutrazol losses by leaching were consistently
lower than the observed
Hydrogeological conditions and problems of regional hydrogeological works of the territory of the Perm Ural and Priurals are characterized. Possibility of providing the population is shown by fresh underground waters. The methodology of mapping of the water-bearing zones on a complex of the methods including the lineament-geodynamic analysis with allocation of geodynamic active zones on the basis of remote researches and geoinformation technologies is considered
The article deals with questions of sense and essence of changes which occurred with the soil covering of planet. Classification of these processes is given for the first time
In this article, the technique to an integrated geoecological assessment on an example of the mining and industrial region of Northern Ural is considered. The geoecological analysis shows that the main influence on the environment has mining and recent geodynamics
This article discusses the problem of protection of coastal areas of the Black and Azov seas. Landslides development mechanism is considered. Reasons for choosing a type and placement location of different landslide structures are given
This article discusses Microbiological factor in processes of corrosion damage of metal underground pipelines in underflooded loessial soils. Aerobic corrosion and anaerobic corrosion is described
In this article we have analyzed the geological structure and hydrogeological conditions of the minefield; we have also shown the characteristic of land planned for recultivation. We have found that recultivation provides different directions
We have analyzed patterns of change in deformations at frost penetration depending on the humidity, density and concentration of the salt solution pore NaCI
We have analyzed patterns of change in deformations at frost penetration depending on the humidity, density and concentration of the salt solution pore of CaCI2
