Resumo: The objective of this work was to evaluate the carbon content of the physical, chemical and oxidizable fractions of soil organic matter (SOM) and to calculate the carbon management index (CMI) in an area managed under an integrated crop-livestock system (ICLS) in the western region of Paraná - Brazil. The experiment was carried out at the experimental farm, belonging to the Universidade Estadual do Oeste do Paraná. Seventeen areas, which are managed in different ways, fifteen in ICLS and two areas of controls (Forest and Haymaking), using the design divided with two nested controls, with three replications were evaluated. Deformed and undisturbed soil samples were collected from all the areas to determine the total organic carbon (TOC), carbon stock, the physical, chemical and oxidizable fractions of SOM and the CMI in the layers of 0-0.05, 0.05-0.1 and 0.1-0.2 m. Little significant changes in the fractions were found for the management of the ICLS area in relation to the Forest and the area of Haymaking, although the Forest presented the best values for most of the studied fractions. It is recommended to adopt sustainable practices, such as ICLS, even though the average fractions tend to take time to match reference areas.

O experimento foi realizado na fazenda experimental, pertencente à Universidade Estadual do Oeste do Paraná. Foram avaliadas dezessete áreas, que foram manejadas de diferentes formas, quinze em ILP e duas testemunhas (Mata e Fenação), sendo empregado o delineamento subsubsubdividido com duas testemunhas aninhadas, com três repetições. Em todas as áreas foram coletadas amostras deformadas e indeformadas de solo para serem determinados o carbono orgânico total, estoque de carbono e as frações físicas granulométricas, oxidáveis e químicas da MOS e o IMC nas camadas de 0-0,05, 0,05-0,1 e 0,1-0,2 m. Alterações pouco significativas das frações foram encontradas para os manejos da área em ILP em relação a mata e a área de fenação, entretanto a mata apresentou os melhores valores para a maioria das frações estudadas. Recomenda-se a adoção de práticas sustentáveis, como a ILP, mesmo que os teores médios das frações tendem a demorar tempo para igualar-se a áreas de referência.EDUFU2020-04-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4770210.14393/BJ-v36n3a2020-47702Bioscience Journal ; Vol. 36 No. 3 (2020): May/June; 743-760Bioscience Journal ; v. 36 n. 3 (2020): Maio/Junho; 743-7601981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/47702/28616Brazil; ContemporaryCopyright (c) 2020 Jeferson Tiago Piano, Carlos Augusto Rocha de Moraes Rego, Andressa Perini Vengen, Jonas Francisco Egewarth, Vanessa Aline Egewarth, Eloisa Mattei, Paulo Sérgio Rabello de Oliveira; Juan López de Herrerahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPiano, Jeferson Tiagode Moraes Rego, Carlos Augusto RochaVengen, Andressa PeriniEgewarth, Jonas FranciscoEgewarth, Vanessa AlineMattei, EloisaOliveira, Paulo Sérgio Rabello deLópez de Herrera, Juan2022-06-14T18:48:21Zoai:ojs.www.seer.ufu.br:article/47702Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-14T18:48:21Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
