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.

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

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 whether the addition of cover crops alone, with no other changes in farm management, can improve surface water quality.

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
