The water balance in forest ecosystems can be affected by many factors. Except for the geographical location and vegatation cover, the soil itself plays just as important role. Properties of the soil determinates the amount of water that can be retained in it and afterwards provided to the plants for physiological and growing proceses. In the context of a changing climate it is important to know the hydrological cycle of the area with specific tree species and limits, when the water availability decrease (hydrolimits). Direct measurements are time consuming and technically demanding, therefore models of water movement in the soil-plant-atmosphere system are used. To setup the models correctly it is essential to know the soil hydraulic properties, in particular the soil water retention curve and saturated hydraulic conductivity. Laboratory measurement of soil water retention curve is rather difficult and in many cases even unavailable. That is why other methods has been developed to estimate soil hydraulic properties based on other easily measurable and better available soil characteristics. These calculations have a common name - pedotransfer functions and most often them are based on dependency of soil hydraulic properties on grain fractions. In our work we have specified soil water retention curves for primeval forest of Dobroč and afterwards we calculated hydrolimits field water capacity, point of decreased availability and wilting point. Since direct measurements were unavailable, we used grain size analysis informations from past research in the 70s. The aim of our work was to estimate soil retention properties and hydrolimits utilizing pedotransfer functions in program ROSETTA.
