In the world which has continuously developing in terms of population and technology, greenhouse gas amounts emitted to the atmosphere have a steady increase, consequently. Therefore, determination of greenhouse emissions in different areas is important for creation and control of the greenhouse gas budget inventory of countries to take the precautions against global climate change. Agriculture is one of these areas to be investigated, especially in countries like Turkey where greenhouse gases emitted from agricultural areas have a large share in the whole budget. Thus, in this study, it was aimed to present the net ecosystem CO₂ exchange between atmosphere and biosphere by field measurements in Kırklareli, Turkey using eddy covariance system during a growing season (covering 258 days) of canola which is one of main oilseed crops of Thrace Region including the experimental area. In order to determine net carbon sink of canola crop, net ecosystem exchange (NEE), ecosystem respiration (Reco) and gross primary production (GPP) variations were obtained by examining different phenological stages. According to the results, carbon sink was mostly observed between flowering and maturity stages while NEE, GPP and Reco during whole growing period were found as -3.5, 10.8 and 7.3 gC m⁻² d⁻¹ respectively.
