Resumo: | The largest production of castor bean (Ricinus communis L.) focuses on Bahia savanna, where the change of land use to their cultivation has been considered a strategy of degraded areas recovery. However, changes in the native soil can arise environmental impacts as greenhouse gases (GHG) emissions. We have assumed that higher GHG emissions come from a change of land use for castor bean cultivation and their subproducts contribute to GHG emissions. The objective of this study was to make the inventory of the emission of GHG resulting from the castor bean cultivation and their sub-products. It was done a study in the municipality of Irecê-BA and were evaluated: changes in carbon (C) soil stocks in cultivated areas with castor bean and Local native forest; a number of senescent leaves and the biomass produced epigeal; GHG emissions from the sub- products of castor bean. The results showed that the sum of senescent leaves and epigeal biomass obtained by castor bean pruning is more than 1.6 Mg ha-1ano-1 and the castor bean residues used in this soil presented N2O emissions close to 600 μg m-2. The emissions from the use of castor oil biodiesel represented less than 10% of the emissions. The change in land use handled high emissions of greenhouse gases, accounting for 87% of the total in CO2eq. Compared to emissions estimated for sugarcane ethanol, castor biodiesel showed emissions 32% lower. |

No entanto, alterações no solo nativo proporcionam impactos ambientais, como emissões de gases de efeito estufa (GEE). Presume-se que elevadas emissões de GEE sejam provenientes da mudança do uso da terra para o cultivo de mamona e que os subprodutos dessa oleaginosa também participam dessas emissões. O objetivo deste trabalho foi realizar o inventário das emissões de GEE decorrentes do cultivo da mamona e seus subprodutos. Foi realizado um estudo na Fazenda Floresta, no município de Irecê (BA), onde foram avaliadas: a mudança no estoque de carbono (C) no solo cultivado com mamona e na floresta nativa local; a quantidade de folhas senescentes e fitomassa epígea; e as emissões de GEE provenientes dos subprodutos da produção agrícola de mamona. Os resultados mostraram que a soma das folhas senescentes e fitomassa epígea obtida pela poda da mamona é superior a 1,6 Mg ha-1ano-1 e o uso da torta de mamona no solo apresentou emissões de N2O próximas a 600 µg m-2. As emissões provenientes do uso do biodiesel de óleo de rícino representaram menos de 10% das emissões. A mudança de uso da terra foi responsável pelas elevadas emissões de GEE, representando 87% do total em CO2eq. Em comparação às emissões estimadas para o etanol de cana-de-açúcar, o biodiesel de mamona apresentou emissões 32% inferiores.Universidade Federal Rural do Semi-Árido2015-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/446810.1590/1983-21252015v28n410rcREVISTA CAATINGA; Vol. 28 No. 4 (2015); 90-98Revista Caatinga; v. 28 n. 4 (2015); 90-981983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/4468/pdf_309Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessFracetto, Felipe José CuryFracetto, Giselle Gomes MonteiroFeigl, Brigitte JosefineCerri, Carlos ClementeSiqueira Neto, Marcos2023-07-03T16:39:46Zoai:ojs.periodicos.ufersa.edu.br:article/4468Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:16.350113Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
