20.500.12556/DKUM-37355 VPLIV PRIDELOVALNIH SISTEMOV NA NEKATERE PARAMETRE KAKOVOSTI TAL The impact of production systems on some soil parametres V letu 2010 smo preučevali vpliv pridelovalnih sistemov (konvencionalni, integrirani, ekološki in biodinamični) na nekatere parametre kakovosti tal: volumska gostota (δvol) in poroznost tal (P), električna prevodnost (EP), pH tal, organski ogljik (Corg), vsebnost rastlinam dostopnega kalija in fosforja (K2O, P2O5), mineralni dušik (Nmin), skupni dušik po Kjeldahlu (Ncel), C:N razmerje (C/N) in število ter masa deževnikov. V poskus smo vključili dve poljščini: oljne buče sorte 'Gleisdorfer Ölkurbis' in ozimno pšenico sorto 'Antonius'. V triletnem poskusu smo ugotovili, da imajo predhodne poljščine statistično značilen vpliv na več parametrov kakovosti tal kot pridelovalni sistemi. Poljščine vplivajo na organski ogljik, K2O, skupni dušik, C/N razmerje ter maso in število deževnikov. Medtem ko pridelovalni sistemi vplivajo na pH tal in organski ogljik (Corg). Najvišja pH vrednost (5,89) in največja vsebnost Corg (1,47 %) je bila izmerjena pri ekološkem pridelovalnem sistemu, najnižja pH vrednost (5,66) in najmanjša vsebnost Corg (1,28 %) pa pri integrirani pridelavi . Ugotovili smo močno korelacijsko povezavo med skupnim N in organskim C (r=0,7137 ter med maso in številom deževnikov (r= 0,7205). In 2010, the impact of different production systems (conventional, integrated, organic and biodynamic) on soil parameters was studied. The studied soil parameters were: bulk density (δvol) and soil porosity (P), electrical conductivity (EP), soil pH, organic carbon (Corg) content, plant available potassium and phosphorus (K2O, P2O5), mineral nitrogen (Nmin) total Kjeldahl nitrogen (Ncel), C:N ratio (C/N) and the number and weight of earthworms. Two field crops were included into the study: oil pumpkins variety 'Gleisdorfer Ölkurbis' and winter wheat variety 'Antonius'. Field crop had more significant effect on soil parameters as production system. Field crop effect was on organic carbon, K2O, total Kjeldahl nitrogen, C:N ratio and the number and weight of earthworms while production systems had statistically significant effect on soil pH and organic carbon (Corg). The highest soil pH (5.89) and the most organic carbon (1.47 %) were measured in case of organic production system, while the lowest soil pH (5.66) and the least of organic carbon (1.28 %) in case of integrated production system. Strong correlations were found between total N and organic C (r = 0.7137) and between number and weight of earthworms (r = 0.7205). kakovost tal / pridelovalni sistemi / organska snov soil quality production systems organic matter true true false Slovenski jezik Angleški jezik Diplomsko delo 2012-08-28 10:48:12 2012-11-14 11:55:52 2022-04-23 23:03:46 2021-04-18 03:21:46 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:CUTCV6NU UNI_Bavec_Simon_2012.pdf UNI_Bavec_Simon_2012.pdf 1 D4D665084DE36049590A580E16468B61 4b0791d2a3de57942fb867d054f73f1a5a8c910047f2708fd2288c3dad898523 389da076-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8d809245-f556-4eda-aaaa-d130ce85c240 https://dk.um.si/Dokument.php?lang=slv&id=49144 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
