USE OF TEST-CULTURES TO ASSESS ECOLOGICAL CONDITION OF URBAN SOILS
Urban soils are studied by means of the physical-chemical techniques, biochemical activity indicators and phytoassay method. We found the basic regularities in the formation of properties of urban soils and reaction of various test cultures to them. Growth and development of test cultures are determined by the ecological properties and condition of urban soils. Watercress showed more responsibility to agrochemical properties of soils compared with the wheat.
