Lotus Spp.: A foreigner that came to stay forever: Economic and environmental changes caused by its naturalization in the Salado River Basin (Argentina)

The Flooding Pampas in Buenos Aires Province is Argentina’s is one of cattle-raising areas. Climatic, topographic and edaphic conditions limit its potential in this area for growing crops such as soybean and wheat. The introduction of L. tenuis in the Flooding Pampas area triggered research based on its ability to tolerate the abiotic stresses that characterize the region and on its role in the improvement of the quality of forage resources. Along with research on abiotic stress tolerance, productive strategies have been developed to enhance the establishment of L. tenuis grassland and beef production. Research on Lotus spp. in the Flooding Pampas has therefore studied not only the biotechnological development and evaluation of new plant resources, but also the accompanying plant diversity, soil microorganisms and symbionts and their impact on environmental dynamics and sustainability. Based on this research, productive strategies have been designed, including continuous evaluation of the impact of cattle production on vulnerable ecosystems. In addition, basic and applied research on grasslands have been combined in order to respond to the environmental impact of the introduction and use of Lotus in these particular ecosystems.Fil: Nieva, Amira Susana del Valle.
