Anaerobna razgradnja hmeljevine glede na različne dodatke - potek temperaturne krivulje ter primerjava vsebnosti rastlinskih hranil pred in po procesu razgradnje : diplomsko deloHalužan, Patricija, agronomkaHmeljevina (trta in listi hmelja), ki ostane po spravilu pridelka hmelja, predstavlja dragocen vir organske mase in hranil za vračanje na kmetijske površine. Na Inštitutu za hmeljarstvo in ... pivovarstvo Slovenije smo v okviru evropskega projekta LIFE BioTHOP, s katerim vpeljujejo v slovenska hmeljišča biokrožno gospodarstvo, na kmetijah Jelen in Gajšek, po obiranju hmelja v letu 2019 postavili poskus, s katerim smo preučevali proces anaerobne razgrajevanje hmeljevine, prepletene z vrvico iz polimlečne kisline (PLA), z različnima dodatkoma (piščančji gnoj in pripravek iz alg in bentonita) v primerjavi s kontrolo (brez dodatka). V kupih smo spremljali temperaturo v času procesa razgradnje pod črno folijo ter primerjali C/N razmerje in vsebnost hranil na začetku in na koncu procesa po petih mesecih. Temperaturni prag za razgradnjo PLA vrvice in za higienizacijo je bil dosežen v kupu z dodatkom pripravka iz alg in bentonita in v kupu z dodatkom piščančjega gnoja. Kupa hmeljevine, kjer smo dodali piščančji gnoj ali pripravek iz alg in bentonita, sta imela ožje C/N razmerje ob koncu razgradnje v primerjavi s kontrolo. V kupu z dodatkom piščančjega gnoja se je nakazala višja vsebnost fosforja ob koncu razgradnje v primerjavi s kontrolnim kupom in kupom z dodanim pripravkom iz alg in bentonita. Vsebnost kalija se je z anaerobno razgradnjo občutno povišala v vseh kupih. Po kakovostnem razredu in vsebnosti težkih kovin bi bil za gnojenje najprimernejši kup z dodatkom Glenorja. PLA vrvica se je v vseh obravnavanjih z anaerobnim procesom po petih mesecih dobro razgradila.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [P.
