Resumo: | The greenhouse gases concentration in the atmosphere have significantly increased since the beginning of the Industrial Revolution. The most important greenhouse gases are CO2, CH4 and N2O, with CH4 and N2O presenting global warming potentials 25 and 298 times higher than CO2, respectively. Most of the N2O emissions take place in soils and are related with agricultural activities. So, this review article aimed at presenting the mechanisms of N2O formation and emission in agricultural soils, as well as gathering and discussing information on how soil management practices may be used to reduce such emissions. The N2O formation in the soil occurs mainly through nitrification and denitrification processes, which are influenced by soil moisture, temperature, oxygen concentration, amount of available organic carbon and nitrogen and soil C/N ratio. Among these factors, those related to soil could be easily altered by management practices. Therefore, understanding the processes of N2O formation in soils and the factors influencing these emissions is fundamental to develop efficient strategies to reduce N2O emissions in agricultural soils. |

Dentre os principais gases estão o CO2, CH4 e N2O, sendo que o CH4 e N2O apresentam 25 e 298 vezes maior potencial de aquecimento global que o CO2. Grande parte das emissões de N2O ocorre nos solos e está relacionada a atividades agrícolas. Neste sentido, esta revisão objetivou apresentar os mecanismos de formação e emissão de N2O em solos agrícolas e reunir e discutir informações sobre como as práticas de manejo do solo podem ser usadas para reduzir tais emissões. A formação de N2O no solo se dá, principalmente, pelos processos de nitrificação e desnitrificação, que são influenciados por fatores como umidade, temperatura, presença de oxigênio, teores disponíveis de carbono orgânico e de nitrogênio e relação C/N do solo. Dentre estes fatores, aqueles relacionados ao solo podem facilmente ser alterados por práticas de manejo. Portanto, conhecer os processos de formação do N2O nos solos e compreender os fatores que alteram as emissões é fundamental para que sejam desenvolvidas medidas eficientes de redução das emissões de N2O em solos agrícolas.Escola de Agronomia - Universidade Federal de Goiás2013-10-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/19871Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 3, Jul./Sep. 2013; 322-338Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 3, jul./set. 2013; 322-338Pesquisa Agropecuária Tropical; v. 43, n. 3, jul./set. 2013; 322-3381983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/19871/15308Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSignor, DianaCerri, Carlos Eduardo Pellegrino2020-07-10T12:43:33Zoai:ojs.revistas.ufg.br:article/19871Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:57.639167Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
