NREC-funded Research in Peer-Reviewed Journal

Thanks to the ongoing work of NREC funded researchers at the University of Illinois and cooperators from the Illinois Fertilizer & Chemical Association, the results of “Soil and crop response to phosphorus and potassium management under conservation tillage” have been published in the Agronomy Journal.

Core Ideas from the published research are:

  • No-till reduced yield relative to strip-till
  • Deep banding P and K with strip-till resulted in no yield advantage over broadcast applications
  • Although there is no agronomic advantage, deep banding effectively reduced soil P and K levels in soil surface layers
  • Critical soil test K levels were greater than current recommendations

Missed the Spring Nitrogen Webinar? You can view the archived version here

On Friday March 20, 2020 Dr. Emerson held a webinar helping farmers and retailers prepare for nitrogen fertilizer decisions as we inch closer to Spring field work and the planting of the 2020 crop.

The pdf’s from the presentation are available here: Spring N Mgt webinar March 2020 and you can also view/hear the archived webinar at this link: March 20 2020 Spring N Webinar Archive . Those needing CEU’s can self-report 1 CEU in Nutrient Management.

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.

Additional copies can be requested by filling out this form: https://forms.gle/wryR4Cf7T6PFZUbi6

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 effective scavenger of nitrogen, reducing the amount of nitrate that leached via soil water.

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 designs, as well as installation requirements and effectiveness under various field and climatic conditions. The research is taking place in Moultrie County. Saturated Buffers – Schoonover

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 of N release to the crop. Dr. Amir Sadeghpour of Southern Illinois University leads this project.  Click here for the latest.  cover crops and termination dates – Sadeghpour

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 nitrogen (N) and phosphorous (P) losses. The study evaluates current tile drainage design and assesses negative impacts on tile drainage and N and P losses.  Click here to download a summary of his current research.  How wide, how deep – Bhattarai
