Resumo: The objective of this study was to evaluate the changes in soil carbon (C) as well as its fractions of physical (particulate organic carbon associated with minerals), chemical (fulvic and humic acids and humins), and oxidizable (F1, F2, F3, and F4) forms of an Oxisol under no-tillage systems (SPD) under different successions and crop rotations in the Cerrado area. In order to do this, the areas of consolidated SPD (10 to 20 years) under the same soil and climatic conditions were selected in Montividiu (GO), with soybean-corn succession (SSM), soybean-millet succession (SSMt), soybean-millet-bean-cotton rotation (RSMFA), crop-livestock integration (ILP), and a native cerrado (CE) area used as a control treatment In each area, samples were collected at depths of 0.0-0.05, 0.05-0.10, 0.10-0.20, and 0.20-0.40 m, respectively. The no-tillage system with crop rotation, followed by no-tillage system with crop-livestock integration, were the ones that presented the greatest potential to increase total carbon content in soil, presenting higher C contents of the granulometric, humic, and oxidizable fractions of the soil organic matter (SOM), compared with the other areas of no-tillage systems with succession of the respective evaluated crops. The no-tillage areas with corn and soybean/millet succession systems showed a similar pattern in soil C accumulation, as well as in the compartments of SOM evaluated.

Para isso, em Montividiu (GO) foram selecionadas áreas de SPD consolidado (10 a 20 anos) sob mesmas condições edafoclimáticas com: sucessão soja-milho (SSM), sucessão soja-milheto (SSMt), rotação soja-milho-milheto-feijão-algodão (RSMFA), integração lavoura-pecuária (ILP) e uma área de cerrado nativo (CE) utilizada como referência. Em cada uma das áreas, foram coletadas amostras nas profundidades de 0,0-0,05; 0,05-0,10; 0,10-0,20; 0,20-0,40 m. O sistema de plantio direto com rotação de culturas seguido do sistema de plantio direto com integração lavoura-pecuária foram aqueles que apresentaram maior potencial de aumento do carbono total do solo, apresentando maiores teores de C das frações granulométricas, húmicas e oxidáveis da MOS (matéria orgânica do solo) em relação as demais áreas de sistema de plantio direto com sucessão de culturas avaliadas. As áreas de sistema de plantio direto com sucessão soja/milho e soja/milheto exibiram padrão semelhante no acúmulo de C do solo, bem como, nos compartimentos da MOS avaliados.UEL2018-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3030810.5433/1679-0359.2018v39n2p533Semina: Ciências Agrárias; Vol. 39 No. 2 (2018); 533-548Semina: Ciências Agrárias; v. 39 n. 2 (2018); 533-5481679-03591676-546Xreponame:Semina.
