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.
Primena modela koji simuliraju procese u biljnoj proizvodnji je sve više zastupljena u istraživanjima u poljoprivredi. U ovom radu razmatrana je mogućnost primene EPIC modela (hidroloskog podmodela) za simulaciju vlažnosti zemljišta. Za analizu su korišćeni rezultati merenja vlage u zemljištu u četvorogodišnjem periodu na zemljištu tipa černozem pod šećernom repom u uslovima navodnjavanja i u prirodnom režimu padavina. Rezultati primene EPIC modela za simuliranje vlažnosti zemljišta pokazuju ograničenja za primenu bez kalibracije na navodnjavanim zemljištima. Na osnovu statističkih pokazatelja može se zaključiti da se simulacija vlažnosti zemljišta EPIC modelom u ovakvim uslovima vlažnosti zemljišta ne može pouzdano izvesti bez kalibracije modela. Ova ograničenja manje su izražena na varijanti bez navodnjavanja. U uslovima manjeg sadržaja vode u zemljištu, model pokazuje bolje rezultate.
