Therefore, proper water management in precision irrigation is crucial to increase productivity and reduce the cost of crop production. Precision irrigation is based on measuring the soil water content, which is often measured with dielectric sensors that measure the apparent permittivity of the soil. Although the sensors are already equipped with a factory calibration function that converts the measured permittivity into volumetric water content, the function does not work properly for all soil types. It is therefore recommended to check whether a soil-specific calibration is required for accurate soil water content measurements. Precise irrigation also requires adequate determination of soil water retention properties, which can be determined using various procedures and methods. In this paper, we presented the results of applying different approaches to determine soil-specific calibration functions using two types of dielectric sensors (SM150T, Delta-T Devices and MVZ 100, Eltratec) in different soil samples obtained from locations in Slovenia where precision irrigation is performed. In addition, the results of determining the water retention properties of the soil using different methods were also compared</dc:description><dc:description xml:lang="sl">Voda postaja redka dobrina, zato je strokovno pravilno upravljanje vode za natančno namakanje ključnega pomena za povečanje primarne rastlinske produkcije in zmanjšanje stroškov rastlinske pridelave v kmetijstvu. Natančno namakanje temelji na meritvah vsebnosti vode v tleh, ki jo običajno merimo z merilniki, ki merijo dielektričnost tal. Merilniki so opremljeni s tovarniško umeritveno funkcijo, ki zaznano dielektričnost pretvarja v volumsko vsebnost vode, vendar slednja ne deluje ustrezno v vseh talnih tipih. Zato je za točne meritve vsebnosti vode v tleh smiselno preveriti, ali je potrebna uporaba talno specifične umeritve. Poleg tega je za natančno namakanje potrebna tudi ustrezna določitev vodozadrževalnih lastnosti tal, ki jih lahko določimo z uporabo več različnih postopkov in metod. V prispevku smo na izbranih vzorcih tal, pridobljenih iz lokacij po Sloveniji, kjer se izvaja natančno namakanje, prikazali rezultate različnih načinov določanja talno specifičnih umeritvenih funkcij z dvema tipoma merilnikov (SM150T, Delta-T Devices in MVZ 100, Eltratec). Primerjali smo tudi rezultate določanja vodozadrževalnih lastnosti tal z uporabo različnih metod</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-4XASF9KO"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-4XASF9KO" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-4XASF9KO/8c2554ec-6b2c-45b6-8d2e-1807f091f5c8/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Biotehniška fakulteta</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-4XASF9KO/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-4XASF9KO" /></ore:Aggregation></rdf:RDF>
