    This article belongs to the Special Issue Plant Root Interaction with Associated Microbiomes[EN] Verticillium wilt is a devastating disease affecting many crops, including hops. This study aims to describe fungal and bacterial populations associated with bulk and rhizosphere soils in a hop field cultivated in Slovenia with the Celeia variety, which is highly susceptible to Verticillium nonalfalfae. As both healthy and diseased plants coexist in the same field, we focused this study on the detection of putative differences in the microbial communities associated with the two types of plants. Bacterial communities were characterized by sequencing the V4 region of the 16S rRNA gene, whereas sequencing of the ITS2 region was performed for fungal communities. The bacterial community was dominated by phyla Proteobacteria, Acidobacteriota, Bacteroidota, Actinobacteriota, Planctomycetota, Chloroflexi, Gemmatimonadota, and Verrucomicrobiota, which are typically found in crop soils throughout the world. At a fungal level, Fusarium sp. was the dominant taxon in both bulk and rhizosphere soils. Verticillium sp. levels were very low in all samples analyzed and could only be detected by qPCR in the rhizosphere of diseased plants. The rhizosphere of diseased plants underwent important changes with respect to the rhizosphere of healthy plants where significant increases in potentially beneficial fungi such as the basidiomycetes Ceratobasidium sp. and Mycena sp., the zygomycete Mortierella sp., and a member of Glomeralles were observed. However, the rhizosphere of diseased plants experienced a decrease in pathogenic basidiomycetes that can affect the root system, such as Thanatephorus cucumeris (the teleomorph of Rhizoctonia solani) and Calyptella spSIThis work was financed through a PRIMA grant (Section 2-2021) and is part of the project PCI2022-132966, funded by the Ministry of Science and Innovation (MCIN), the State Investigation Agency (MCIN/AEI/10.13039/501100011033), and by the European Union “NextGenerationEU”/Recovery Plant, Transformation and Resilience (PRTR).

    Naloga obravnava načine vrednotenja prostorskih vplivov avtocest z vidika varovanja kmetijskih zemljišč. Izhodišče raziskave je vse večja ogroženost najboljših kmetijskih zemljišč, ki so temelj prehranske varnosti naroda. Ogrožajo jih različne človekove dejavnosti, med njimi tudi gradnja prometne infrastrukture, kot so avtoceste. Ker je dosedanja gradnja avtocest v večini primerov potekala preko najboljših kmetijskih zemljišč, smo v nalogi raziskali možne metode, s katerimi bi te posege v prostor lahko bolje vrednotili in poiskali najoptimalnejšo rešitev za njihovo umeščanje v prostor. Opozorili smo, da je dosedanje vrednotenje vplivov prostorskih ureditev na kmetijska zemljišča neustrezno, saj je glede na metodološko praznino na tem področju že čutiti resne posledice z vidika trajnostnega prostorskega načrtovanja in zagotavljanja prostorske kohezije. Zato v nalogi sledimo rešitvam, ki bodo v bodoče kmetijska zemljišča ustrezneje obravnavala in vrednotila, s čimer bi se v največji možni meri zmanjšali prostorski vplivi na kmetijska zemljišča in njihovo porabo. Izbrano metodo večkriterijskega odločanja, ki po našem mnenju najučinkoviteje obravnava omenjeno problematiko, smo preverili na primeru južnega odseka severnega dela hitre ceste ob koridorju tretje razvojne osi med Velenjem in avtocesto A1. Rezultati preverjanja so pokazali, da povzroča predlagana najustreznejša varianta hitre ceste od Velenja do Šentruperta v Savinjski dolini največje vplive na kmetijska zemljišča od vseh obravnavanih variant na tem odseku. Na podlagi ugotovitev v magistrskem delu je v primerjalne študije variant in okoljska poročila nujno vpeljati novo ali dopolnjeno metodo vrednotenja prostorskih vplivov prostorskih ureditev z vidika varstva kmetijskih zemljišč kot del sistemskih rešitev pri urejanju in načrtovanju prostora v Sloveniji.Thesis entitled "˙Evaluation of motorway\u27s spatial impact in context of agricultural land protection" stresses the issues of agricultural land sealing, which failed to be reduced despite the relevant legislation.
