PURR publishes and archives digital datasets from researchers across campus and welcomes all kinds of open data from images and videos to spreadsheets and source code. PURR has nearly 4000 data management plans, over 4000 registered researchers, and over 1500 research projects (as of early 2020). You can search for datasets of interest.
In particular, there are several agronomy datasets that might be of interest to researchers and practitioners alike. They cover topics including: corn, alfalfa, sorghum, nitrogen, soil, remote sensing, and much more.
Another set of data regards GPS tracks for machine harvest of wheat in Colorado. this one is an outcome of the Purdue Open Ag Technology and Systems Center (OATS).
Some undergraduates compiled and packaged weather and USDA corn and soybean statistics.
You may want to search PURR for data applicable to your research question, your management decision, or that might be useful in a class project.
