Illinois NREC – Illinois agriculture’s investment in Nutrient Research and Education

Focused on enhanced nutrient utilization, increased crop production, and protecting water quality

Maximize efficiency. Minimize losses. Mitigate environmental impacts.

Cover crops and water quality

In a field-size study area, Dr. Williard and his team are in the middle of a multi-year project at Southern Illinois University farms to look at relationships between cover crops and N availability to corn. What they have learned so far is that cereal rye is an...

New saturated buffer designs

Building upon past research, Dr. Schoonover and his team are demonstrating an alternative design of saturated buffers that address commonly encountered issues with the Best Management Practices (BMP) of saturated buffers. This new research will look at the alternative...

Do termination dates influence corn N requirements?

Current N management guidelines in Illinois are not adjusted for inclusion of cover crops especially with different cover crop termination dates. The termination date can influence the decomposition rate of cover crops in a corn cropping system and change the dynamics...

How wide? How deep?

Understanding the influence of tile depth and spacing on nutrient loss - does depth or distance count for something?  Research under way by Dr. Rabin Bhattarai from the University of Illinois leads a study investigating how tile depth and spacing variations impact...

Cover cropping on a large scale

Using cover crops shows the potential to reduce nutrient loss, but most of this research has been done at the plot or field scale levels. This project explores whether the use of cover crops can effectively be scaled up to the watershed – not just a field – and...

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...

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...

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...
