Additional Data

Database S1
Field-level data on maize and soybean yields, sow dates, and associated weather variables used in this study. One hundred fields were randomly sampled from each county in each year, with a different random sample used each year. All information that could be used to identify individual producers, such as latitude and longitude, has been removed to comply with USDA policies on personal identifiable data. Dataset is available at Science Online. Identical files are also accessible at
