PROPERTIES TUNDRA SOILS IN THE NORTH OF THE EUROPEAN PART OF RUSSIA REMEDIATED AFTER OIL POLLUTION [№ 10 ' 2013]
Conducted field and laboratory studies of physical and chemical properties of remediated different methods tundra-gley soils of the Republic of Komi in the comparative analysis with background soils. It is show the main outcome of reclamation is the radical change of the properties of soils due to a number of reasons depending on the type of reclamation: change in topography, water-physical properties of soils, formation of a regime of functioning and other direction of the evolution of data soils.

FUNCTIONING OF SPECIALISED SOIL CONSTRUCTIONS IN THE CONDITIONS OF MOSCOW CITY [№ 10 ' 2013]
An important component of urban greening is the using of a large number of grassy vegetation requiring a modern approach to the formation of the soil cover (soil constructions), its properties and modes. Soil constructions with different structure were created on the Soil Station of MSU, where were studied their properties and regimes. It was established, that the specific of structure of the soil profile significantly influence on the growth and development of plants. Along with this, introduction of humates and supply of polluting substances provide a significant effect on the biomass.

THE MOVEMENT OF MOISTURE IN THE GRAY FOREST SOIL IN THE CONDITIONS OF PRESSURE AND NOT PRESSURE ABSORPTION [№ 12 ' 2010]
The authors carried out field experiments on the study of the vertical movement of moisture in the gray forest soil of Vladimir opole under the conditions of pressure and not pressure absorption. It is shown that with the presence of pressure on the surface of soil expressed shaping of the preferred flows of waters, which accomplish significant mass transfer, occurs. During the fine dispersed irrigation is observed the gradual moistening of soil profile, which subsequently contributes to the best retention of moisture in the root-inhabited layer.

BIOCLIMATIC RECOURSES AND PHYSICAL CHARACTERISTICS OF CHERNOZEMS AND LIVER-COLORED SOILS OF ORENBURG PREDURAL [№ 5 ' 2007]
Soil subtypes of Orenburg Predural confined to typical plant associations from pile-motley grass with chernozems leached till wormwood-feather grass-fescue with liver-colored soils are researched in this article. It is established, that soil density, its permeability and other water-physical characteristics are changed at zonal consecution in connection with change of humus content at comparative constancy of granulometric staff, sizes of specific surface area and solidity of soil hard phase.

APPREHENSIBILITY APPRAISAL OF MATTERS MIGRATION MODEL IN SOIL OF DIFFERENT LEVEL AT LYSIMETRIC DRAIN [№ 3 ' 2007]
Water block of physically proved models of different level, models with homogeneous porosity (PEARL) and models, accounting double porosity of soil (MACRO) was parameterizated and tested at results of water regime studying of turf-podzol hardloamy soils of large lysimeters of MSU. Experimental laboratories and field dynamic data were used as in parameters. The analysis of models apprehensibility appreciated at data of lysimetric drain on the lower border (1,5 m) of soil showed that OGH parameters were the main physical supplying of models, accuracy making of forecasting. It is necessary to use there parameters for models tuning. The model MACRO described better lysimetric drain at vegetation period thanks to account of quick flows at macropores and cracks originated at the period of intense precipitations in the model.

GRAVITATIONAL FLOW OF MOISTURE AND ITS ROLE IN SOLE EVOLUTION: DIRECT LYSIMETRIC RESEARCHES [№ 6 ' 2006]
The problems of gravitational moisture flows formation in structural textured-varied grey forest and turf-podzol soils are regarded in this article. Endowment of fast flows of moisture in mass carry is appreciated here. Forming speed of hydraulic conductivity soil structure and evolution of properties of hard soil phase - grain-size classification, structure, are researched at the long lysimetric experiment.
