Abstract
V magistrskem delu z naslovom Terroir Bizeljskega sem preučila dejavnike terroirja na Bizeljskem, s katerimi sem se srečala že v svojem diplomskem delu. Bizeljsko je z ugodno klimo in ostalimi mikroklimatskimi dejavniki zelo primerno za rast vinske trte. Ker naravne danosti omogočajo odlične pogoje za vinarstvo in prepoznavnost območja, sem preučevanje terroirja nadaljevala na celotnem delu Bizeljskega, kjer raste vinska trta. Vpliv dejavnikov sem ugotavljala za dve izbranih sorti vinske trte, in sicer za rumeni plavec in rumeni muškat. Zaradi boljšega razumevanja terroirja sem izbrala šest vinogradov na petih lokacijah. Lokacije vinogradov se med seboj razlikujejo po matični podlagi, mineralni sestavi tal, geokemični sestavi tal, nadmorski višini, ekspoziciji, naklonu, sončnem obsevanju, kislosti tal. Vinogradi ležijo na aloformaciji Globoko, na Bizeljski formaciji, na meji med Bizeljsko in Drnovsko formacijo ter na Laški formaciji. Bistvena razlika med vinogradi je predvsem v količini karbonatov in silikatov. Mineralna analiza vzorcev tal vinogradov je potrdila, da imata največji delež karbonatov Janeževa Gorca 2 in Janeževa Gorca 1, sledijo Brezovica, Orešje in Nimnik. Tla vinograda Stara vas imajo največ kremena, torej namesto karbonatov prevladujejo silikati. Iz geokemične analize tal vinogradov je razvidno, da je največ silicija in železa v vinogradu Stara vas, kalcija v Janeževi Gorci 2, kalija in aluminija pa v vinogradu Orešje. Vinogradi ležijo na nadmorski višini 186-352 m in imajo jugovzhodno, jugozahodno oziroma severozahodno usmerjenost. Nakloni vinogradov so od 14 % do 32 %. Leta 2017 je imel največjo povprečno dnevno sončno obsevanje vinograd Orešje, najnižjo pa vinograd Brezovica. Rezultati pH so potrdili, da se vinograd Stara vas nahaja na rahlo kislih tleh, vinograd Orešje na rahlo bazičnih tleh in vinogradi Brezovica, Nimnik, Janeževa Gorca 1 in Janeževa Gorca 2 na bazičnih tleh. S programom QGIS sem zaradi potrditve posameznih dejavnikov terroirja izdelala GIS karte.

Title:Terroir of Bizeljsko
Abstract:
In the Master's thesis Terroir Bizeljsko I studied the factors of Terroir at Bizeljsko, that have also been previously studied in the Bachelor's thesis. Natural resources of Bizeljsko are excellent conditions for wine production and recognizability of the area. That is why the Terroir study has been extended and continued on the entire wine productive area of Bizeljsko. With favourable climate and other microclimate factors, Bizeljsko is very appropriate for wine production. The influence of factors have been explored on two vine species, Rumeni plavec and Rumeni muškat. For better understanding of terrroir six vineyards have been chosen at five different locations. Location of vineyards vary based on bedrocks, mineral and geochemical structure of ground, altitude, aspect, slope, insolation, acidity of ground. Vineyards lie on aloformation Globoko, formation Bizeljsko, border between formations Bizeljsko and Drnovo, and Laško formation. Essential difference between vineyards is mainly the amount of carbonates and silicates. From the mineral analysis of vineyard ground samples it is evident, that the highest share of carbonates is at Janeževa Gorca 2 and Janeževa Gorca 1, Brezovica, Orešje and Nimnik are following. Ground at vineyard Stara vas has the highest share of quartz and silicates are dominating over carbonates. Geochemical analysis of ground showed that the highest share of silicon and iron is at vineyard Stara vas, calcium at Janeževa Gorca 2 and potassium and aluminium at vineyard Orešje. Vineyards lie on altitude ranging from 186-352 m and have south-east, south-west and north-west orientation. Slope of vineyards are from 14% to 32%. In 2017 vineyard Orešje had the average highest daily, while vineyard Brezovica had the lowest. Ph results have confirmed that vineyard Stara vas is located on slightly acidic ground, vineyard Orešje on slightly basic ground and vineyards Brezovica, Nimnik, Janeževa Gorca 1 and Janeževa Gorca 2 also on basic ground. With QGIS program GIS maps were made to confirm individual factors of terroir.
