Considering the consequences of eutrophication for Argentina, which are likely to worsen with COVID-19; that one of its main causes is the excessive use of chemical fertilizers; and that tax measures may be effective to modify human behaviors, the goal is to evaluate the way in which the national tax system can help to restore the quality of the Argentine eutrophic water resources and to develop normative proposals in that direction. To achieve this goal, the Article will first develop the link between tax measures and environmental protection; second, it will study the legal experience of other countries when applying taxes on fertilizers to tackle eutrophication; and, finally, it will analyze the different alternatives within the Argentine tax system to discourage the use of fertilizers. In short, the Article shows that Argentina is not currently taking advantage of environmental taxation to modify agricultural practices involved in the eutrophic process of its water resources.en-USAll Rights Reserved.Environmental lawEnvironmental protectionWater lawArgentinaTaxationArticle
