Soil and its properties in the urban environment

Abstract

Soils in the urban environment have a character antrosoils, technosoils, at best case cultisoils.
They are formed most often by reclamation of areas devastated by construction activities
(antrosoils). They therefore have a wide range of properties, often unfavorable for the growth of
plants. The work states optimal, permissible and undesirable texture, structure, moisture, biotic
and some pedochemical features (pH, humus content, Na + , Mg 2+ ). The following are criteria for
evaluating the nutrient content of the soil (N, P, K, Ca, Mg, CaCO 3 , C tot ) and their optimal ratios
and limits for 23 other risk elements including heavy metals in the soil. The importance, functions
and deficiency of physiologically important trace elements in plants and their contents in the soil
are also discussed.
