Revisão: Análise dos estoques de carbono no solo sob diferentes coberturas vegetais no Brasil

Anthropic activities have caused an increase in the concentration of greenhouse gases in the atmosphere, mainly due to changes in land use that alter the ability of soils to store CO2. The present study seeks to review current publications on changes in soil carbon stock under different vegetation cover published in recent years and to make a critical and systemic assessment of the subject, considering the methodologies used in each work and the different types of soil management and use in various regions of Brazil. For data collection, 35 articles published in the last ten years that correlated with the theme were selected. The survey of the articles sought to characterize the Brazilian ecosystems and summarize the main published data on carbon stocks in ecosystems and subsequently the estimates of stocks in environments under changing land use. The results showed that the different vegetation coverings present distinct, however positive capacity to store carbon in the soil in Brazil and that variables such as management, texture, physical, chemical and biological attributes are significant factors and can and directly influence the results.
