Overcoming Forage Challenges in Mesophytic Grasslands—The Advantages of Lotus tenuis

Previous studies in the Salado River Basin (Argentina) demonstrated that the introduced forage species, Lotus tenuis Waldst. & Kit. ex Wild. (Fabaceae), possesses high tolerance to abiotic stresses—including flooding, alkalinity, salinity, and drought. The efficient biological fixation of nitrog...

The efficient biological fixation of nitrogen in a region with a scarce presence of native legumes is one of its advantages.

In this study, seasonal parametric investigations of L. tenuis, regarding its photosynthetic and ionic status, modifications in CW composition, and concomitant nutritional quality, were performed.
