Abstract:Corn (maize) is one of the main raw materials for ethanol production in the European Union. Among agricultural feedstock dedicated for biofuels, it is put under regulation in terms of greenhouse gas emission in the life cycle of ethanol production. This study is focused on corn cultivation in Poland and the possibilities to mitigate the greenhouse gas emission at the stage of crop cultivation. The main opportunities come from N fertilization optimization (rates and assortment) as well from increase in soil organic carbon sequestration by improving crop management (reduced tillage and no-tillage). The results show that ethanol produced from conventional tillage corn cultivation, including typical GHG emissions from N fertilizer production, guarantee the at least 35% greenhouse gas savings to petrol as fossil fuel reference. Moreover, the future required life cycle GHG emission savings of 50-60% for corn based ethanol production shall be reached in Poland if applying reduced and no-tillage cultivation of corn.
