Resumo: | The population growth and the climate changes impose challenges to society, especially regarding food supply and the maintenance of desirable soil conditions. Besides, it is necessary to reduce greenhouse gas emissions. Hence, there is a necessity of studies addressing the understanding of soil conditions under different land uses, as soils can become carbon pools or sources depending on management practices. This study was conducted in soil profiles of Amazon Plinthosols under different land uses: undisturbed forests, cattle ranching pastures, and mixed crops. Soil density and carbon fraction were assessed at four depths (0-5, 5-10, 10-20, and 20-40 cm), while particle size and mineralogy were examined at 0-20 and 20-40 cm. Soils under undisturbed forests presented lower densities and higher carbon fractions when compared to other land uses. These soils also presented the highest carbon stock; however, the Tukey test indicated no significant differences. Soil densities were lower in forest environments. Cattle ranching pastures presented higher carbon stocks when compared to mixed crops (at age 10 years). Our results indicated that proper soil management practices are needed to maintain the soil productive capacity after converting forested areas for other uses. Plinthosols, due to its textural and mineralogical characteristics, presented high amounts of quartz, demonstrating how sensitive these environments are to changes in the landscape due to deforestation and how unstable the maintenance of carbon stocks is because of such conditions. This study provides useful information to the understanding of the carbon stock in Amazon Plinthosols. It may be helpful to improve the Brazilian Inventory of Anthropogenic Emissions and Removals of Greenhouse Gases and to understand the impacts of land-use change. |

Além disso, há uma evidente necessidade de reduzir as emissões de gases de efeito estufa, notadamente àquelas causadas por mudanças no uso do solo. Portanto, há necessidade de estudos que abordem o entendimento das condições do solo sob os diferentes usos do solo, uma vez que esses podem se tornar fontes de carbono dependendo das práticas de manejo. Este estudo foi conduzido em perfis de Plintossolos Amazônicos sob: florestas primárias, pastagens para pecuária e plantios mistos de restauração florestal. A densidade e o teor de carbono foram avaliados em quatro profundidades (0-5, 5-10, 10-20 e 20-40 cm), enquanto as propriedades físicas foram examinadas nas profundidades de 0-20 e 20-40 cm. Solos sob florestas primárias apresentaram as menores densidades e os maiores teores de carbono quando comparados a outros usos da terra. Esses solos também apresentaram o maior estoque de carbono. Entretanto, não foi observada diferença significativa pelo teste de Tukey para ambas variáveis. As pastagens apresentaram maiores estoques de carbono quando comparados aos plantios mistos (aos 10 anos). Nossos resultados indicaram que práticas de manejo adequadas são necessárias para a manutenção da capacidade produtiva do solo após a conversão de florestas para outros usos. Os Plintossolos, por suas características texturais e mineralógicas, apresentaram elevados teores de quartzo, notadamente nas camadas superficiais, demonstrando quão sensíveis às mudanças na paisagem. O estoque de carbono no solo é, portanto, sensível às mudanças na sua cobertura. Este estudo fornece informações úteis para o entendimento do estoque de carbono em Plintossolos na Amazônia Brasileira, bem como para aprimorar as estimativas realizadas no Inventário Nacional de Emissões de Gases de Efeito Estufa.Universidade Federal de Santa Maria2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3821110.5902/1980509838211Ciência Florestal; Vol. 31 No. 2 (2021); 749-765Ciência Florestal; v. 31 n. 2 (2021); 749-7651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/38211/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/38211/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessBastos, Alexis de SousaSanquetta, CarlosManiesi, VanderleiSanquetta, Mateus Niroh InoueCorte, Ana Paula Dalla2021-08-24T13:31:11Zoai:ojs.pkp.sfu.ca:article/38211Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-08-24T13:31:11Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
