Resumo: The objective of this work was to evaluate the short‑term and the residual effect of retorted oil shale (ROS) rates on the C retention of crop residues in the soil. The mineralization and C retention of soybean leaves and stems enriched with 13C were evaluated, in soil with and without history of ROS application and in the presence and absence of increasing ROS rates. There was a short‑term effect of ROS on C retention in the soil. This effect only occurred with the mixture of leaves + 3 Mg ha‑1 ROS, in which C retention in the soil surpassed by 21% the one observed with the sole application of leaves. ROS has the potential to retain C in the soil.

Foram avaliadas a mineralização e a retenção de C de folhas e talos de soja enriquecidos com 13C, em solo com e sem histórico de aplicação de XR e na presença e na ausência de doses crescentes de XR. Houve efeito de curto prazo do XR sobre a retenção de C no solo. Esse efeito ocorreu somente com a mistura de folhas + 3 Mg ha‑1 de XR, em que a retenção de C no solo superou em 21% aquela observada com a aplicação isolada das folhas. O XR apresenta potencial de reter C no solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPetrobrasLeão, Ricardo ElsoGiacomini, Sandro JoséRedin, MarcielSouza, Eduardo LorensiSilveira, Carlos Augusto Posser2014-11-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19106Pesquisa Agropecuaria Brasileira; v.49, n.10, out. 2014; 818-822Pesquisa Agropecuária Brasileira; v.49, n.10, out. 2014; 818-8221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/19106/12776https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19106/11656info:eu-repo/semantics/openAccess2014-11-14T18:14:43Zoai:ojs.seer.sct.embrapa.br:article/19106Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-14T18:14:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
