Abstract: Agro ecosystems are considered to be potential producers of greenhouse gas (GHG) emissions are considered as the main driver of climate change. Thus assessment of gas exchange in these ecosystems is necessary to reduce input of agro sector in climate change. In this study biosphereatmosphere interactions were investigated on a light loam soil (Calc(ar)i-Endohypogleyic Luvisol) in different managed grassland ecosystems of the Training farm of the Aleksandras Stulginskis University in 2009 within the frame of a European COST Project. The main objective of this investigation was to determine the impact of fertilizers, their rates and combinations on GHG emissions and productivity of abandoned, semi-natural grassland. Obtained results were compared with emissions from sown grassland. GHG emission measurements were run in June-September, when meteorological conditions were optimal for intensive plant and soil biota physiological processes, in absence of frosts stress. Results of this investigation will be compared to results of analogical investigations of natural, poor nutritional value swards not commonly used on the farms. Accounting for GHG emissions of grassland ecosystems may be important to evaluate and interpret fluxes measurements at regional and ecosystem levels
