NEW Guide to Illinois MRTN Available

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.

The guide can be downloaded here or you can request printed copies by filling out this short form.

Notes on Fall Fertilization from University of Illinois

With harvest winding down in most of Illinois after another year with high to very high yields, it’s time to review some basics of fall fertilization. Neither fertilizer nor grain prices are historically high, so there’s reason to be aware of costs while making sure to cover the nutrient basics.

Read the latest research and guidelines here.
