Nitrogen Modeling Survey

Many corn farmers in DE, MD, and PA can expect to receive an invitation in the mail to participate in a university study this month. The study is being conducted by researchers with the University of Delaware, University of Maryland, and Penn State University.

The goal of this study is to understand farmer interest in using an in-season nitrogen modeling tool to guide nutrient management decisions. During the study participants will have the opportunity to learn about and engage with in-season nitrogen modeling tools. Results from this study will help us develop strategies to better serve farmers in this region.
Eligible farmers may participate from home on a computer, tablet, or smartphone. Internet access is required. In the online activity, participants will be asked to make in-season nitrogen management decisions for a simulated corn field. In addition to a $50 participation payment, participants will earn additional money (up to $100 extra) based on decisions during the 30-35 minute activity. Participants will receive their payment as a Walmart or Amazon gift card or via PayPal within one week of completing the online activity.

Participation requires a unique participant code, which can be found on the mailed invitation letter. If you do not receive a letter in the mail but you would like to participate, you may contact the research team to receive a login code and instructions. Please contact Badri Khanal at the University of Delaware (302-455-7555; bkhanal@udel.edu).
