Variações de curto prazo nas emissões de CO2 do solo em diferentes sistemas de manejo do cafeeiro.

However, information about short-term alterations of CO2 fluxes in soils of tropical regions are scarce. So, the objective of this study was to evaluate such variations in coffee plantations in Latosol (Oxisol). The CO2 emissions were not affected by environmental abiotic factors, such as temperature and soil water evaporation, but they were significantly correlated with the carbon content of microbial biomass (R=0.90, P<0.05). It happens a close relationship between root activity and soil CO2 emission in coffee plantations.pdfpt-BROpen AccessCarbon global cyclePerennial cropCarbonic gasCafeicultura::Solos e nutrição do cafeeiroArtigo
