Applications of models that simulate the processes in crop production are very frequent in agricultural research. Possibility of application of EPIC model for soil moisture simulation is considered in this paper. Results of measurements of soil moisture in chernozem type of soil under sugar beet in the conditions of irrigated and rainfall regime within period 1987-1990 were used for the analysis of possibility of application of EPIC model in simulation of soil water content. Application of EPIC model for soil moisture simulation in both irrigated and unirrigated conditions are rather limited for application without calibration on irrigated soils. The model shows better result in soil with lower water content. Apart from model calibration for soil water content modelling it is necessary to use instruments for continual monitoring since longer and more reliable time series will help calibration and validation of the model for such purposes.
