Abstract
Na pokušalištu Maksimir 2024. godine uspješno je instaliran i validiran napredni CRNS uređaj za mjerenje vlažnosti tla. Validacija uređaja, provedena usporedbom s gravimetrijskom i TDR metodom pokazala je visoku točnost CRNS. U travnju 2024., razlika u mjerenjima između CRNS i gravimetrijske metode iznosila je samo 1,8 %, dok je u rujnu, pri usporedbi s TDR metodom razlika bila 5,7 %. Iako rezultati CRNS mogu varirati u odnosu na metode koje mjere manji volumen tla, njegova sposobnost obuhvata većih površina i dubljih slojeva tla čini ga neprocjenjivim alatom u poljoprivredi i ekološkim istraživanjima. Analiza efektivnih oborina i normi navodnjavanja za različite usjeve, poput pšenice, kukuruza, soje i suncokreta, provedena u računalnom programu CROPWAT za razdoblje od 1988. do 2017. godine, pokazuje kako usjevi različito reagiraju na raspoloživost efektivnih oborina u smislu normi navodnjavanja, koje su najmanje kod pšenice (56 mm), zatim kukuruza i suncokreta (105 mm), a najveće kod soje (124 mm). Korištenje CRNS-a u kombinaciji s drugim metodama omogućava bolje planiranje navodnjavanja prema specifičnim potrebama kultura, što je ključno za održivu poljoprivredu i optimalno korištenje vodnih resursa pogotovo u uvjetima navodnjavanja.
Abstract (english)
At the Maksimir experimental field in 2024, an advanced Cosmic Ray Neutron Sensor (CRNS) for measuring soil moisture was successfully installed and validated. The validation of the device, conducted by comparing it with the gravimetric and TDR methods, demonstrated the high accuracy of the CRNS. In April 2024, the difference in measurements between the CRNS and the gravimetric method was only 1.8 %, while in September, when compared with the TDR method, the difference was 5.7 %. Although CRNS results may vary from methods that measure smaller soil volumes, its ability to cover larger areas and deeper soil layers makes it an invaluable tool in agriculture and ecological research. The analysis of effective precipitation and irrigation norms for different crops, such as wheat, corn, soybean, and sunflower, conducted using the CROPWAT software for the period from 1988 to 2017, shows how crops respond differently to the availability of effective precipitation in terms of irrigation norms, which are lowest for wheat (56 mm), followed by corn and sunflower (105 mm), and highest for soybean (124 mm). The use of the CRNS in combination with other methods allows for better irrigation planning according to the specific needs of crops, which is crucial for sustainable agriculture and optimal use of water resources, especially in irrigation conditions.
