Understanding the flux of nitrous oxide from the eucalypt soil in monoculture and Integrated Crop–Livestock–Forest systems

The Brazilian agricultural sector is largely responsible for nitrous oxide (N2O) soil emissions, mainly due to beef cattle and the use of synthetic nitrogen fertilizers. Therefore, Brazil looking measures, such as integrated crop–livestock– forest (ICLF), increase productivity reduce greenhouse gas emissions in this sector. component within system plays a positive role context climate change, conservation, carbon dioxide (CO2) sequestration, biodiversity protection. aim study was evaluate effect management rainfall on N2O eucalypt monoculture soils ICLF systems. Manual static chambers were used collect samples, from November 2013 October 2014, four treatments, i.e., one (F) three modalities (livestock–forest [LF], livestock–crop–forest [LCF], crop–livestock–forest [ICLF]). A chromatograph with an electron capture detector measure concentrations. results showed that considerably affected fluxes across all indicating main factor increasing emissions. During wet season, levels ranged 0.158 0.482 kg N-N2O ha-1 treatments. dry treatments behaved like sinks N2O. Moreover, flux did not differ between This indicates forestry systems affect fluxes.
