Resumo: | The objective of the work was to evaluate the carbon stock and soil aggregationin different management systems in the municipality of Aquidauana-MS. Soilsamples were collected in the 0.0–0.1 m layer, in six areas: exposed soil (ES),conventional brewing system (CB), no-till system (NT), sugar cane (SC), permanentpasture (PP), and native forest (NF). From the samples, the: total organic carbon(TOC) was determined, density of the soil (Sd), being calculated the carbon stock(EstC), and the variation in the carbon stock (ΔEstC), in addition to the aggregatestability analysis, obtaining: weighted average diameter (WAD), geometric meandiameter (GMD), and percentage of aggregates retained in the sieves. The resultswere analyzed in completely randomized design (CRD), in addition to canonicalanalysis. The highest Sd values were observed in the ES 1.53 Mg m-3, CB 1.46 Mgm-3, NT 1.47 Mg m-3, and SC 1.46 Mg m-3 systems. The TOC levels in the PP andNT areas were higher than the NF. EstC has the same TOC pattern. As the areas ofPP and NT presented values of WAD, GMD similar to NF. As PP, NT and NF areashad more than 60% of their aggregates larger than 2mm. A canonical analysisindicated the formation of 3 groups, one with ES and CB, another with onlySC, and the third composed of NT, PP, and NF. The ES committed the CB to thecarbon stock and soil aggregation in layer 0–10, whereas PP and NT increasedthe carbon stock in that same layer. |

Os resultados foramanalisados em delineamento inteiramente casualizado (DIC) e análise canônica.Os maiores valores de Ds foram observados nos sistemas SE 1,53 Mg m-3,PC 1,46 Mg m-3, PD 1,47 Mg m-3 e CA 1,46 Mg m-3. Os teores de COT das áreasde PP e PD foram superiores ao da MN. O EstC apresentou o mesmo padrãode COT. As áreas de PP e PD exibiram valores de DMP e DMG semelhante aMN. As áreas de PP, PD e MN tiveram mais de 60% dos seus agregados maioresque 2 mm. A análise canônica indicou a formação de três grupos, um com SEe PC, outro apenas com CA e o terceiro composto de PD, PP e MN. O SE e o PCcomprometem o estoque de carbono e a agregação do solo na camada 0–10cm, já a PP e o PD aumentaram o estoque de carbono nessa mesma camada.Zeppelini Publishers2020-06-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/69510.5327/Z2176-947820200695Revista Brasileira de Ciências Ambientais (Online); v. 55 n. 2 (2020): RBCIAMB - ISSN 2176-9478 - Junho; 242-255Brazilian Journal of Environmental Sciences (Online); Vol. 55 No. 2 (2020): RBCIAMB - ISSN 2176-9478 - June; 242-2552176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESporhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/695/528Copyright (c) 2020 Brazilian Journal of Environmental Sciences (Online)info:eu-repo/semantics/openAccessFalcão, Karina dos SantosMonteiro, Felipe das NevesOzório, Jefferson Matheus BarrosSouza, Camila Beatriz da SilvaFarias, Paulo Guilherme da SilvaMenezes, Roniedison da SilvaPanachuki, ElóiRosset, Jean Sérgio2022-03-25T22:12:11Zoai:ojs.www.rbciamb.com.br:article/695Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2022-03-25T22:12:11Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
