Abstract

Vodni režim tla analiziran je pomoću bilance vode u tlu koja predstavlja kvantitativan izraz za manjak odnosno višak vode u tlu. Ključni proces vodnog režima tla je proces evapotranspiracije koji predstavlja onu količinu vode koja se gubi isparavanjem vode s površina tla (evaporacija) i isparavanjem vode s biljaka (transpiracija). S klimatskim promjenama odnosno promjenama u godišnjem hodu temperature zraka, količine oborine i drugih klimatskih elemenata mijenja se i evapotranspiracija. Bilanciranje vode u tlu provedeno je prema metodi Thornthwaite za 9 različitih lokacija u RH (Osijek, Slavonski Brod, Križevci, Varaždin, Karlovac, Gospić, Pazin, Knin, Hvar) kao predstavnika poljoprivrednih podregija i dva različita klimatološka razdoblja (1961.-1990. i 1991.-2020.). Provedenom analizom utvrdile su se razlike u razdobljima po poljoprivrednim regijama. Ukupna prosječna stvarna evapotranspiracija u oba promatrana razdoblja se ne razlikuje previše, a najveći iznos postiže u razmaku od 6. – 7. mjeseca, te se uspoređivanjem rezultata može utvrditi da je manja u suvremenom razdoblju (1991. – 2020.) Usporedbom bilance vode poljoprivrednih regija utvrđeno je kako ukupni prosječni godišnji manjak vode postiže najveću razinu u Jadranskoj regiji, a nedostaje u Gorskoj regiji u oba promatrana razdoblja (1961. – 1990. i 1991. – 2020.). Ukupni prosječni godišnji višak vode najviše je zabilježen u Gorskoj regiji (Gospić), zatim u Jadranskoj i Panonskoj regiji.

Abstract (english)

The water regime of the soil was analyzed using the soil water balance, which represents a quantitative expression for the lack or excess of water in the soil. The key process of the water regime of the soil is the process of evapotranspiration, which represents the amount of water that is lost through evaporation of water from the soil surface (evaporation) and evaporation of water from plants (transpiration). With climate changes, i.e. changes in the annual course of air temperature, amount of precipitation and other climatic elements, evapotranspiration also changes. Soil water balancing was carried out according to the Thornthwaite method for 9 different locations in the Republic of Croatia (Osijek, Slavonski Brod, Križevci, Varaždin, Karlovac, Gospić, Pazin, Knin, Hvar) as representatives of agricultural subregions and two different climatological periods (1961-1990). and 1991-2020). The conducted analysis determined the differences in the periods by agricultural regions. The total average actual evapotranspiration in both observed periods does not differ too much, and the highest amount is reached between 6 and 7 months, and by comparing the results it can be determined that it is lower in the modern period (1991 - 2020). By comparing the water balance of agricultural region, it was determined that the total average annual water deficit reaches the highest level in the Adriatic region, and is lacking in the Gorska region in both observed periods (1961 - 1990 and 1991 - 2020). The total average annual surplus of water was highest in the Gorska region (Gospić), followed by the Adriatic and Pannonian regions.
