Cover Crop Guide 2.0

Cover Crop Guide 2019.digital

We have worked closely with Cover Crop experts and our partners at the Illinois Fertilizer & Chemical Association to publish an updated Cover Crop Guide. Our original Cover Crop Guide was widely distributed and helped farmers make informed decisions about getting started with Cover Crops. This guide is updated with the latest science and includes links to other resources which can help make the best decisions.

Updated iOS MRTN Calculator now available

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

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.

You can also view an archived version of Dr. Nafziger’s October 19th webinar. 1 CEU in NM is available.

Bloomington, Illinois, May 11, 2018 – Illinois Nutrient Research & Education Council (NREC) today announced Dr. Shani Golovay, of Greenville, as Research Manager.

A native of Pocahontas, Illinois, in Bond County, Golovay brings to NREC a wide breadth of experience in agriculture and academia. She has held teaching and research positions at several different Institutions as well as working as a Research Manager for Monsanto.   She also served as Grants Manager for the University of Florida’s Integrated Pest Management (IPM) program where she facilitated grant work across 13 southern state’s land grand institutions and worked to encourage collaboration among the universities and to network researchers doing similar work. She received her BS from the University of Illinois in Agronomy, her MS from Mississippi State University in Biotechnology/Cotton Physiology and her PhD from Mississippi State University in Biochemistry/Soil and Environmental Fate of Herbicides.

“Shani’s experience, particularly in research coordination and the ability to drive collaboration, made her the ideal candidate for this role,” said Jeff Kirwan, Chairman of NREC. “One of NREC’s primary charges is to pursue nutrient research practices that optimize nutrient use efficiency, ensure soil fertility and address environmental concerns regarding fertilizer use. Shani’s technical expertise and her classroom teaching experience will help take the research that we have funded to the next level by transferring the knowledge into real-world applications and in a format that farmers and retailers can use in their daily operations.”

Golovay will provide technical agronomic expertise to the NREC Council and committees in the development and implementation of effective research projects and the dissemination of research results. She will also provide leadership on developing strategic research priorities that align with the overall goals of the organization and promote nutrient efficiency and stewardship.

“I’m very excited to serve as a bridge between growers/retailers and researchers,” Golovay said. “The work of NREC is incredibly valuable to the industry and I look forward to working with the Council and our stakeholders to identify research priorities and then translate the results into actionable messages that will move the needle on nutrient efficiency.”


 About Illinois NREC

The Illinois Nutrient Research & Education Council (NREC) was created by state statute in 2012. Funded by a 75-cent per ton assessment on bulk fertilizer sold in Illinois, NREC provides financial support for nutrient research and education programs to ensure the discovery and adoption of practices that address environmental concerns, optimize nutrient use efficiency, and ensure soil fertility.  

A 13-member NREC Council annually solicits, reviews and funds projects that fulfill the organization’s mission.
