| Popis: | Autori ponajprije upozoravaju na globalne i lokalne štete od katastrofalnih klimatskih promjena, s posebnim osvrtom na ekstremno suha razdoblja bez dovoljno oborina – sušu u Hrvatskoj. U cilju popularizacije nacionalnog projekta natapanja (NAPNAV), slijede podaci o pedološkim i hidropedološkim uvjetima i potrebama vode za uzgoj poljoprivrednih kultura u Hrvatskom zagorju. Proračuni potrebe vode za uzgoj odabranih poljoprivrednih kulture su obavljeni po modelima funkcioniranja sustava biljka-klima i sustava tlo-biljka-klima. U modelu sustava biljka-klima, komponente su referentna evapotranspiracija (ETo), evapotranspiracija kulture (ETk) i koeficijent kultura (kc). U modelu sustava tlo-biljka-klima, komponente su referentna evaopotranspiracija (ETo), evapotranspiracija kulture (ETk), efektivne oborine 75 %-tne vjerojatnosti pojava, dubina i vodne konstante tla. Na kraju su preporuke za identifikaciju projekata i preliminarno planiranje sustava natapanja, te opća načela gospodarenja izgrađenim sustavima za natapanje. The authors primarily warn of global and local damages from catastrophic climate change, with special reference to extremely dry periods without sufficient precipitation - the drought in Croatia. In order to popularize the national irrigation project (NAPNAV), the following are data on pedological and hydropedological conditions and water requirement for growing agricultural crops in Hrvatsko zagorje. Calculations of the water requirement for the cultivation of selected agricultural crops were carried out according to the models of the functioning of the plant-climate system, and soil-plant-climte system. In the model of plant-climate system, the components are reference evapotranspiration (ETo), crop evapotranspiration (ETk) and crop coefficient (kc). In the model of soil-plant-climate system the components are reference evapotranspiration (ETo), crop evapotranspiration (ETk), effective precipitations with a 75% probability of occurrence, depth and soil water constant. At the end, there are recommendations for project identification and preliminary planning of irrigation systems, as well as general principles of management of constructed irrigation systems. |
