This is a commentary on Brookshire et al. 26, 5404-5413 For the Northern Great Plains, Brookshire, Stoy, Currey, and Finney (Global Change Biology, 2020) analyze satellite‐based reconstructions of greenness and foliar nutrition and isotopic composition from herbarium samples. Their results of greater productivity coupled with reduced N availability are part of an inflection in our understanding of the global N cycle as much of the terrestrial biosphere appears to be experiencing reduced N availability.
