Resumo: The study aimed to evaluate changes in organic carbon concentrations and oxidizable fractions of soil organic matter in and around forest fragments in the Atlantic Forest (AF) and Cerrado (CE) biomes. Soil samples were collected from four forest fragments, two in the AF and two in the CE, in which three internal points were sampled: edge (ED), half radius (HR), and center (CF), as well as a point in the surroundings; no-tillage (NT) and permanent pasture (PP) in AF and CE, respectively. The total organic carbon (TOC) content and the carbon of the oxidizable fractions (F1, F2, F3, F4) were quantified. The CF of the AF forest fragments showed the highest TOC and C contents in the labile fractions F1 and F2 (the fraction most sensitive to changes in the environment), with the lowest contents in the ED. In the CE, the fragments showed different TOC contents and dynamics, with the highest TOC and F1 contents in the HR and the lowest in the CF of fragment 1, while in fragment 2 the highest TOC contents were in the CF and the lowest in the ED and HR, but they did not differ in the contents of the F1 and F2 fractions. The lower levels of TOC and C labile in the ED of the fragments are due to the negative interference of the edge effect, which, through abiotic factors, has modified the species composition and structure of the plant community, altering the dynamics of C storage and emission.

Foram coletadas amostras de solo em quatro fragmentos florestais, dois na MA e dois no CE, nos quais foram amostrados três pontos internos: borda (BO), metade do raio (MR) e centro (CF), além de um ponto no entorno; plantio direto (PD) e pastagem permanente (PP) na MA e no CE, respectivamente. Quantificou-se os teores de carbono orgânico total (COT) e o carbono das frações oxidáveis (F1, F2, F3, F4). O CF dos fragmentos florestais do MA, apresentaram os maiores teores de COT e de C nas frações lábeis F1 e F2 (fração mais sensível a alterações no ambiente), sendo os menores teores nas BO. No CE, os fragmentos apresentaram teores e dinâmica de COT distintos, sendo os maiores teores COT e F1 no MR e menores no CF do fragmento 1, já no fragmento 2 os maiores teores de COT foram no CF e os menores na BO e MR, porém não se diferem nos teores das frações F1 e F2.  Os menores teores de COT e C-lábil nas BO dos fragmentos são provenientes das interferências negativas do efeito de borda, que através de fatores abióticos modificaram a composição de espécies e a estrutura da comunidade vegetal o que altera a dinâmica de armazenamento e emissão do C.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2024-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/826910.32404/rean.v11i1.8269Revista de Agricultura Neotropical; v. 11 n. 1 (2024): REVISTA DE AGRICULTURA NEOTROPICAL; e8269REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 11 No. 1 (2024): REVISTA DE AGRICULTURA NEOTROPICAL; e82692358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/8269/6068https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOzório, Jefferson Matheus BarrosRosset, Jean Sérgio Oliveira, Naelmo de SouzaSouza, Camila Beatriz da SilvaFarias, Paulo Guilherme da SilvaBispo, Luan SoaresSchiavo, Jolimar Antonio2024-03-27T16:52:44Zoai:ojs.pkp.sfu.ca:article/8269Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2024-03-27T16:52:44Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
