Resumo: | The CO2 measured from the soil is the microbial activity provided by several biogeochemical processes and its investigation can answer about the factors associated with the environmental condition in the Caatinga. Thus, the aim of this study was to assess the soil CO2 emissions in two Caatinga environments, comparing them with the environmental conditions of the soil and climate, in the Alagoas' Semiarid. Microbial activity was evaluated through the CO2 released from the soil, which was soaked up with a KOH solution. A rain gauge was installed to obtain precipitation data, in addition to soil temperature measurements at 10 cm from the surface. The water content, carbon content and soil organic matter were evaluated. The highest emission of CO2 from the soil in the two evaluated areas occurred at night, due to the milder soil temperature; The release of CO2 was variable, due to the properties of the soil, climate and vegetation; Soil carbon and organic matter showed high values in the Caatinga areas, demonstrating great biogeochemical and nutrient cycling activity; It is recommended that future studies on CO2 kinetics be carried out, in order to compare values and better understand the dynamics of this environment. |

Desse modo, o objetivo desta pesquisa foi avaliar as emissões de CO2 do solo em dois ambientes de Caatinga, comparando com os condicionantes ambientais do solo e do clima, no Semiárido de Alagoas. A atividade microbiana foi avaliada pelo CO2 liberado do solo, onde foi absorvido por uma solução de KOH. Foi instalado pluviômetro para obter índices de precipitação e a leituras de temperatura do solo a 10 cm da superfície. Foram avaliados o conteúdo de água, teores de carbono e matéria orgânica do solo. A maior emissão de CO2 do solo nas duas áreas avaliadas ocorreram no período noturno, em virtude da temperatura do solo apresentar-se mais amena; A liberação de CO2 apresenta variável, em decorrência das propriedades do solo, clima e vegetação; O carbono e a matéria orgânica do solo apresentaram valores elevados nas áreas de Caatinga, demonstrando grande atividade biogeoquímica e de ciclagem de nutrientes; Recomenda-se que estudos futuros sobre cinética de CO2 sejam realizados, de modo a comparar valores e compreender mais a fundo a dinâmica do ambiente.EDUFU - Editora da Universidade Federal de Uberlândia2023-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6607910.14393/RCG249466079Caminhos de Geografia; Vol. 24 No. 94 (2023): Agosto; 164–179Caminhos de Geografia; Vol. 24 Núm. 94 (2023): Agosto; 164–179Caminhos de Geografia; v. 24 n. 94 (2023): Agosto; 164–1791678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/66079/36503Copyright (c) 2023 Geovânia Ricardo dos Santos, Kallianna Dantas Araujo, Mayara Andrade Souza, Sinval Autran Mendes Guimarães Júniorhttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSantos, Geovânia Ricardo dosAraujo, Kallianna DantasSouza, Mayara AndradeGuimarães Júnior, Sinval Autran Mendes2023-08-01T12:37:46Zoai:ojs.www.seer.ufu.br:article/66079Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2023-08-01T12:37:46Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
