| Abstract : | The paper presents the results of a study on the impact of the cultivation of crops which may serve as a substrate for a biogas plant on the atmosphere. Subjects addressed in the study cover a range of issues related to greenhouse gas (GHG) emissions from this area of agricultural activity. The amounts of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) emitted to the atmosphere in the selected cultivation technologies of beet, maize for silage and grasses were calculated. Emissions of GHG from chemical fertiliser production corresponding to the quantities used in the individual technologies were analysed, and amounts of the emitted above-mentioned pollutants originating from diesel fuel used during agricultural treatments conducted with the use of agricultural machinery were calculated. Emission values were expressed in equivalent units – . The study demonstrated that technologies which result in the highest quantities of emission are maize cultivation technologies – the average value for the study crops is 1 428 490.56 g ha–1 CO2eq. The lowest level of pollutants in the form of emitted greenhouse gases originates from grass cultivation and its average value is 904 661.28 g ha–1 CO2eq. |
