Description:	The worldwide increase in the concentration of greenhouse gases (GHGs) has caused climate changes that have not been observed since 800,000 years ago. As a result, the heating of the Earth’s surface has been higher in the last three decades than recorded until 1950 (IPCC 2013). N2O is considered a very active gas in the process of global warming due to its high ability to absorb infrared radiation and is a sta- ble gas in the atmosphere, contributing approximately with 6% of the radiative potential of GHGs, and has a half-life of 120 years. Its global warming potential (GWP) is 310 times higher compared to CO2 and its concentration in the atmosphere has increased in recent decades, reaching 324,2±0,1 ppb. This increase has been attributed to increased amounts of nitrogen fertilizers used in agriculture, conversion of forest areas for agriculture, increased fires, intensification of livestock, etc. (Bustamante et al. 2012). Thus, agriculture is the main activity responsible for N2O emissions to the atmosphere as a result of oxidation of organic matter and complex microbial processes associated with management practices on ecosystems. Integrated production systems can be considered a strategy to reduce soil N2O emissions in the Brazilian Cerrado (Carvalho et al., 2014).
