Abstract

The intensification of climate change in the area of Eastern Croatia is leading to more frequent and longer drought periods, resulting in changes in the water regime of the area and difficulties in managing soil and water for agricultural purposes. For this reason, there is an increasing need for the construction of irrigation systems for stable and profitable agricultural production. Therefore, this study aims to determine the suitability for irrigation of drained agricultural land in the Eastern Croatia area. Data from the meteorological stations Osijek-Čepin and Gradište kod Županje were used to analyze basic climate indicators for the period from 2003 to 2022. A slight trend of decreasing annual precipitation and increasing monthly air temperatures by 0.09°C per year was identified. High variability of precipitation and continuous increase in water deficit and decrease in water surplus in soil were also determined. Regarding the suitability classes for irrigation needs, on the researched drained agricultural land in Eastern Croatia (with a total area of 74,871.2 ha), the P-2 class is the most represented (63.2%), followed by the P-3 class (26.0%) and the P-1 class (9.8%). Only 1 % of the researched area were classified as unsuitable (N-1 class), and the permanently unsuitable N-2 class was not identified.

Abstract

Uslijed sve izraženijih klimatskih promjena, na području istočne Hrvatske dolazi do sve češćih i duljih sušnih razdoblja što rezultira promjenama u vodnom režimu područja te poteškoćama u gospodarenju tlom i vodom za potrebe poljoprivrede. Iz tog razloga javlja se sve češća potreba za izgradnjom sustava navodnjavanja u svrhu stabilne i isplative poljoprivredne proizvodnje. Stoga ovaj rad ima za cilj odrediti pogodnost za navodnjavanje dreniranog poljoprivrednog zemljišta (tala) na području istočne Hrvatske. Za analizu osnovnih klimatskih pokazatelja korišteni su podaci s meteorološke postaje (m.p) Osijek-Čepin i m.p Gradište kod Županje, za vremensko razdoblje od 2003. do 2022. godine. Utvrđen je blagi trend sniženja godišnjih količina oborina te porast mjesečnih temperatura zraka od 0,09 °C godišnje. Također utvrđena je visoka varijabilnost oborina te kontinuirani porast nedostatka vode u tlu i smanjenje viška vode u tlu. Na istraživanom dreniranom poljoprivrednom zemljištu istočne Hrvatske (ukupne površine 74.871,2 ha), obzirom na klase pogodnosti za potrebe navodnjavanja, najviše je zastupljena klasa P-2 (63,2 %), a zatim slijede klasa P-3 (26,0 %) i klasa P-1 (9,8 %). Svega 1 % istraživanih površina svrstan je u klasu nepogodnosti N-1, a klasa trajno nepogodnih tala N-2 nije utvrđena.
