Descripción
Agricultural soils are considered a source of N2O emissions. This is due to the influence of many cropping and land management practices on the soil microclimate and cycling of C and N. Tillage practices affect chemical, physical and biological soil properties, and these interactions together with climatic conditions influence the magnitude of N2O emissions (Passianoto et al., 2003; Oorts et al., 2007). Currently, there is no consensus in the literature on the differences in field N2O emissions or mitigation between conservation tillage and conventional tillage (Snyder et al., 2009). Moreover, there is a lack of data on long-term tillage system studies, particularly in Mediterranean agro-ecosystems. The aim of this study was to evaluate the effects of long-term (>17 yr) tillage systems (conservation tillage and conventional tillage) and crop rotation on N2O emissions. After soil has been 18 years under three tillage systems, conventional tillage induced lower cumulative N2O cumulative emissions than conservation tillage (NT and MT) in wheat-vetch rotations under Mediterranean agro-ecosystems.
