Sharing knowledge, sharing research
It just takes a research meeting in San Antonio to bring the NREC-funded research to the forefront of the agronomy world.

The app version of the Illinois MRTN (Maximum Return to Nitrogen) Rate Calculator has recently been updated with current research values from research conducted under the direction of Dr. Emerson Nafziger and with the on-farm work of Illinois Fertilizer & Chemical Association.
The update also supports new iOS versions and improves usability.
You can download/update the app from the Apple App Store by searching for MRTN Rate Calculator or by clicking this link.
For help in using the app – see these instructions: MRTN Apple App instructions
In the first five years of NREC hundreds of nitrogen rate trials have been conducted across Illinois. This research has resulted in a new publication: “Using the Maximum Return to Nitrogen (MRTN) System in Illinois”.
This guide explains the terminology and the process for determining the Maximum Return to Nitrogen
(MRTN), which is the N rate that maximizes the dollar return to N. It also addresses commonly asked
questions and dispel myths about nitrogen use, all in an effort to support sound agronomic principles, and
to increase economic return while respecting our environment.
