Abstract:Človeštvo s svojimi potrebami nenehno vpliva na okolje, kar se odraža pri podnebnih spremembah. Kmetijstvo kot osnovna človekova dejavnost prispeva 10–12 % vseh emisij toplogrednih plinov antropogenega izvora. Okoljski odtis je eden izmed načinov vrednotenja negativnih vplivov na okolje in je kot orodje uporabljen tudi v magistrskem delu, pri čemer smo ovrednotili različne pridelovalne sisteme – konvencionalni (KONV), integrirani (INT), ekološki (EKO), biodinamični (BD) in kontrola (K) ter različne kulturne rastline. Analiziranih je devet različnih poljščin in zelenjadnic, pridelanih v okviru trajnostnega poskusa od leta 2011 do 2015. Pri tem je v programu SPIonWeb ovrednoten okoljski odtis pridelave posamezne poljščine in zelenjadnice (Atot) ter indeks okoljske učinkovitosti pridelka (EEI). Rezultati kažejo, da imajo alternativni pridelovalni sistemi (EKO in BD) manjši Atot pri pridelavi pšenice, pire, oljnih buč, soje, koruze, stročjega fižola, paprike in paradižnika. EEI izbranih rastlinskih vrst ni nujno manjši v alternativnih pridelovalnih sistemih, saj je izračun odvisen od okoljskega odtisa pridelave Atot kot tudi od količine pridelka. EEI pridelka je v EKO, BD in K lahko manjši v primerjavi z intenzivnima pridelovalnima sistemoma, kljub manjšemu pridelku. To je posledica prepovedi vnosa hitro topnih mineralnih gnojil, herbicidov in sintetičnih pesticidov, ki doprinesejo k večjemu okoljskemu odtisu pridelave. Takšno situacijo lahko opazimo pri pšenici, piri, koruzi, delno pri bučah, soji, paradižniku, solati. V prihodnosti bo potrebno nameniti veliko pozornosti načinom, kako se najbolje prilagoditi podnebnim spremembam v kmetijstvu, ter izboljšavam pridelovalnih tehnik za zmanjševanje negativnih vplivov v prihodnje.

Title:ECOLOGICAL FOOTPRINT OF FIELD CROPS AND VEGETABLES DEPENDING ON PRODUCTION SYSTEM
Abstract:Humanity, with its ever growing needs, continuously impacts on the environment, which leads to climate change. Agriculture as a basic human activity contributes 10–12% of all greenhouse gas emissions of anthropogenic origin. Measuring ecological footprints are one way of assessing the negative impacts on the environment. In this thesis different production systems were evaluated - conventional (CONV), integrated (INT), organic (ORG), biodynamic (BD) and a control (K) system as well as nine different crops and vegetables produced in the scope of a sustainable experiment conducted between 2011 and 2015. The SPIonWeb system has been utilized to evaluate the ecological footprint of the production (Atot) and the Ecological Efficiency Index (EEI). The results show that the alternative production systems (ORG and BD) have a smaller Atot in wheat, spelt, oil pumpkin, soybean, maize, beans, paprika and tomatoes. The EEI of the selected cash crop is not necessarily lower in alternative production systems, since the calculation depends on the Atot as well as the yield. The EEI of the crop in ORG, BD and K can be lower than in intensive production systems, despite lower yields. This is due to the prohibition of the use of fast soluble mineral fertilizers, herbicides and synthetic pesticides, which contribute to a higher Atot in CONV and INT. This situation can be observed in wheat, spelt, maize and partly in oil pumpkins, soybeans, tomatoes and lettuce. In the future, we need to pay more attention to adapting to climate change in agriculture and improving the production techniques to reduce negative impacts.
