AbstractRapid warming in the Arctic threatens to amplify climate change by releasing the region’s vast stocks of soil carbon to the atmosphere. Increased nutrient availability may exacerbate soil carbon losses by stimulating microbial decomposition or offset them by increasing primary productivity. The outcome of these competing feedbacks remains unclear.

1 INTRODUCTION Grazing animals are influential controls on the estimated 30% of our total soil organic carbon (SOC) stocks held in the two-thirds of agricultural lands grazed globally (Dondini et al., 2023). Mismanagement of domesticated grazing animals, along with land-use change, has historically led to significant SOC loss on grazed lands (Sanderman et al., 2017).
