Empirical dependencies of a plant-soil coefficient have been formulated upon the sum of evapotranspiration in the analysed period of the grass regrowth and at capillary potential at the end of this period. The coefficient values in the relationships have been estimated from measurements in the Institute for Land Reclamation and Grassland Farming lysimetric station in the upper Notec River valley carried between 1973 and 1992. The relationships were verified by measurements in the same station in 1993-95. The verification has proven a satisfactory agreement of evapotranspiration measured and calculated according to the proposed method. The relationships can be recommended for the operational calculation of water consumption by grasslands in the Notec River valley
