2022 Nitrogen Use Efficiency Workshop

Craig Chandler | University Communication


August 1–3, 2022

University of Nebraska–Lincoln
Nebraska Innovation Campus and Nebraska East Union

You can participate in the Hackathon competition as a Graduate Student Team of two to four members.


Managing nitrogen fertilizer is a challenging problem that deals with the interactions between environmental, genetic, and management (E x G x M) variables. Solving this challenging and “wicked” problem requires skills to clean, analyze, and distill information from big datasets into sound agronomic decisions.

For this competition, university teams (2 to 4 students/team) will have 15 days just prior to the workshop to develop a new nitrogen fertilizer recommendation tool for in-season applications using a dataset, common to all teams. This tool needs to be robust enough to account for within-field variability, and it needs to be applicable across the US Corn Belt.

Your tool will be evaluated based on soil and crop science, accuracy, and commercial feasibility. You will be judged by those at the workshop. Teams are encouraged to think creatively; fresh, new ideas that hold to known scientific principles will be given higher scores.


  • Participants are expected to follow an honor system. This includes not asking for or receiving help outside the team (e.g., graduate student advisors, professors, or other students).
  • External data can be obtained if it is publicly available and it is cited in your presentation (e.g., weather, SSURGO, google images, or county yield information). External data that is not freely available to everyone is not permitted (e.g., paid for satellite imagery).
  • This data may only be used for the purpose of this contest. This data is not to be used in publications, educational material, or other analyses.
  • Privately sharing code or data outside of teams is not permitted.
  • Each participant will need to sign a non-disclosure agreement prior to the start of the competition.

How to Participate

Review the Hackathon section with all the details of the competition. Feel free to contact the organizer for any clarification. Complete the main registration form indicating that you want to participate in the Data Hackathon after the selection of Graduate students. You can also participate in the poster competition (individual competition). Each member of the team needs to register for the Hackathon.

Informative Meeting July 1

A meeting will be conducted July 1 with all Graduate Students interested in participating in the competition. At least one member per group must attend this meeting. You can drop your participation after the informative meeting.

Activity and Data Release

July 15 each group will receive an email with the instructions and the dataset to complete the task.

During the Event: Details for Oral Presentation

On Aug. 2 from 11 to 11:50 a.m., each group will have the chance to present their results in a 10-minute presentation in the main auditorium. A slide presentation can be used as support. Participants will need to share their results and the approach (key steps) to achieve them.

Hackathon Awards

Three groups will be selected by the judges to receive an award (1st $400, 2nd $300, 3rd $200). Hackathon competition winners* will be announced on Aug. 3 at 11:15 a.m.

*One member per team will be asked to complete the paperwork needed before leaving the conference to receive their award check.

Registration is limited to the first six teams.
