Climate change mitigation potential of widespread cover crop adoption in U.S.

This geospatial dataset represents climate change mitigation benefits from
widespread cover crop adoption on U.S. cropland. We simulated changes in
soil organic carbon stocks and nitrous oxide fluxes over a 20-year period
for baseline cover crop adoption rates (derived from historical adoption
rates) and a high cover crop adoption (80%) scenario in the continental
U.S. Data were generated using the DayCent ecosystem model driven by
cropping histories in the USDA National Resources Inventory (NRI) and
associated agricultural management data. Here we present the mean and
standard deviation of annual soil organic carbon stock changes and nitrous
oxide fluxes for both baseline and high cover crop adoption scenarios on a
county level.
