1 Introduction Mixed grasslands that combine forage legumes such as alfalfa (Medicago sativa) with perennial grasses like tall fescue (Festuca arundinacea) are vital for sustainable livestock grazing and forage production in temperate regions (Bi et al. 2019; Clemensen et al. 2017). These systems not only provide high-quality forage but also contribute to ecological sustainability by improving soil health, promoting biodiversity, and supporting carbon sequestration (Büchi et al. 2020).
