Evaluation of Water Content in Soils of Žitný Ostrov from the Point of View of Its Exploitation for Biosphere

Abstract The lithospheric zone between the soil surface and first ground water horizon, respectively table, has a character of three-phase system. It consists solid phase having fine to rough disperse granularity. This creates structure porous environment with characters that can be physically determined. occurs in pores different forms state its bond phase. Its energetic is clearly quantified by means moisture retention curve. gas fills up value full porosity, i.e. it part not saturated water. Therefore, this called aeration zone. volume occurring corresponds concentration framework hydrological cycle components. serves as resource for vegetation cover. data used calculation were particular types area, depth hydrolimits (wilting point, point decreased availability, field capacity) thickness. content capacity (FWC) wilting (WP) critical interval cover given locality. Water from available no properties free water, plants have developed root system such suction pressure, able overcome soil. Calculated results verified help monitored content. Both calculated measured values show affected appurtenant type. human activity landscape directly affects dynamics resource, either quantitative or qualitative viewpoint. affect demonstrated changes regime, table amplitude fluctuation. paper brings evaluation Žitný ostrov area.
