    Increases in respiration rates following management activities in croplands are considered a relevant anthropogenic source of CO2. In this paper, we quantify the impact of management events on cropland respiration fluxes of CO2 as they occur under current climate and management conditions. Our findings are based on all available CarboEurope IP eddy covariance flux measurements during a 4-year period (2004-2007). Detailed management information was available for 15 out of the 22 sites that contributed flux data, from which we compiled 30 types of management for European-scale comparison. This allowed us to address the question of how management activities influence ecosystem respiration. This was done by comparing respiration fluxes during 7,14, and 28 days after the management with those observed during the matching time period before management.
