FUNCTIONING OF SPECIALISED SOIL CONSTRUCTIONS IN THE CONDITIONS OF MOSCOW CITY
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.
Key words: soil constructions, physical properties and modes of soil, urban greening, humates.

APPREHENSIBILITY APPRAISAL OF MATTERS MIGRATION MODEL IN SOIL OF DIFFERENT LEVEL AT LYSIMETRIC DRAIN
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.
