20.500.12556/DKUM-20771 VPLIV VEČLETNE ALTERNATIVNE OBDELAVE TAL NA ZBITOST TAL Influence of multiannual alternative soil tillage the soil years. V diplomski nalogi smo preučevali vpliv večletne alternativne obdelave tal na horizontalno zbitost tal. Meritve smo izvedli z vlečenim horizontalnim penetrometrom na parceli, kjer težka tla že več let alternativno obdelujejo z gruberjem (rahljalnikom). Poskusno parcelo smo razdelili na tri manjše parcelice glede na dosedanji način obdelave; oranje, gruber 1 in gruber 2. Zanimalo nas je, kako dosedanja obdelava vpliva na horizontalno zbitost tal v globinah 15, 25 in 35 cm. Ugotovili smo, da je najmanjša zbitost tal v globini 15 cm pri obravnavanju oranja (40,98 N/cm²) in največja pri obravnavanju gruber 1 (62,57 N/cm²). V globini 25 cm je bila najmanjša zbitost tal pri oranju in pri obravnavanju gruber 1 (91,67 N/cm²) in največja zbitost tal pri obravnavanju gruber 2 (122,48 N/cm²). V globini 35 cm je bila najmanjša zbitost tal pri obravnavanju gruber 2 (115,83 N/cm²) in največja pri obravnavanju oranje (124,77 N/cm²). Rezultati poskusa kažejo, da je zaradi večletnega alternativnega načina obdelave manjša zbitost tal le v globini 35 cm, kjer zaradi oranja prihaja do nastanka plazine, medtem ko v ostalih dveh globinah tega vpliva nismo opazili. In this dissertation we've examined the chisel influence of multiannual soil tillage on horizontal soil compaction. All the measurements were made by horizontal penetrometer on the land which is tillaged alternatively by chisel for several years. The land split into 3 parcels which were defined by the way of tillage: chisel 1, chisel 2 and plowing. We were interested in finding out how to way of tillage reflects on horizontal soil compaction in the depth of 15 cm, 25 cm and 35 cm. The result were as follows: in the depth of 15 cm we found out that the soil was most compacted in the chisel 1 (62,57 N/cm²) and least compacted in the area of plowing (40,98 N/cm²). In the depth of 25 cm we found out that the soil was most compacted in the chisel 1 (91,67 N/cm²) and least compacted in the area in the chisel 2 (122,48 N/cm². In the depth of 35 cm we found out that the soil was most compacted in the chisel 2 (115, 83 N/cm²) and least compacted in the area of plowing (124,77 N/cm²). The result of our study shower that by using alternative methods for several years the soil compaction was decreased only in the depth of 35 cm, where we noticed a slippery layer in the area of plowing. We noticed no such layer in the other two areas (chisel 1 and chisel 2). zbitost tal načini obdelave tal horizontalno penometriranje soil compaction ways of soil tillage horizontal penometer true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-09-30 10:08:07 2011-10-13 09:26:24 2022-04-14 08:14:42 2023-12-27 03:31:03 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:6JFGP2Y6 VS_Bedrac_Klemen_2011.pdf VS_Bedrac_Klemen_2011.pdf 1 4B42FD658B049EAAF2150979EC5CDC2F 0e5fa3648a3038a8d65f52dba423d3cc0d3b75718daf952059bd8492c9acf4e7 b2df106f-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/1750e51f-5278-4e3f-8dbc-55c780f972e9 https://dk.um.si/Dokument.php?lang=slv&id=25972 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
