| † Data were retrieved by state collaborators and DuPont Pioneer agronomists. ‡ Approximate date at which 50% of final corn area was planted in 2017 at each location. Soil water balance was initialized around prior crop harvest in the previous year (2016), assuming 50% available soil water. TBD: still to be determined. |
