Special DSSAT Oral and Poster Sessions at the 2023 ASA-CSSA-SSSA Annual Meeting

The Annual Meeting of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America (ASA-CSSA-SSSA) is the grand confluence of scientists, professionals, and organizations focused on agronomy, crop science, and soil science. The 2023 Annual Meeting was held from October 29 through November 1, 2023 in St. Louis, MO and provided a rich array of presentations, discussions, and interactions among the meeting participants.

Sponsored Special Sessions

The University of Florida and the DSSAT Foundation sponsored three distinguished Special DSSAT Oral (I and II) and Poster Sessions during this meeting. The sessions were part of the ASA Section: Climatology and Modeling and aimed at bringing forth discussions on innovative research and advancements in crop modeling with emphasis on DSSAT.
