Course of soil layer water content in agricultural cultivated soil during years 1999 and 2000

Abstract

Water regime, which determines soil productive ability, depends on water inflow and outflow into or out of unsaturated soil zone. Soil as vital entity of the biosphere is not homogenous medium (Mikulec, 2004). Unsaturated soil zone is one of the most important and complicated part evaluated water movement in hydrologic cycle. The water supply in the unsaturated soil zone is directly influenced by a water transfer through its upper and lower boundary. The lower boundary is usually delimited by water groundwater table (Veliskovd et al. 2005). The upper boundary is the soil surface with or without plant canopy. It reacts directly on meteorological and climate conditions (Stehlovd, 2004). It is a place enabling the water inflow from precipitation into lower layers of a soil profile. Water store in unsaturated soil zone was determined by monitoring of water content in soil profile and groundwater tables in localities in region around Danube in Slovakia. The localities relate to agricultural cultivated soil. The aim of contribution is to estimate course of integral water contents in different layers of soil profiles at Slovakia localities near Danube (BaC and Cilifakd Radvafl)and to compare these actual integral water contents and integral water contents that are related to hydrolimits (Stekauerova et.al., 2002, Orfanus, 2005).
