4R4U Project Header Image

Heritage FS, Kankakee County Farm Bureau, and Ford-Iroquois Farm Bureau are teaming up to demonstrate the impact of implementing 4R nutrient stewardship practices.  The project will utilize N-WATCH soil sampling sites to test a variety of nitrogen application processes and use of nitrogen inhibitors.

  
  
Crop Update- Abbott Farms7/24/2018

​Chase Aylesworth, Crop Specialist with Heritage FS, located in St. George is working on a 4R4U nitrogen management plot.

The plot was sprayed with fungicide on July 14th at the VT stage.  The product that was used was Approach Prima at 6.8 oz./acre.

The aerial image isn't necessarily showing us a whole lot at this point.  We have gotten timely rainfalls and no mass amounts of rain at any given time.  It will be interesting to see if the next image gives us a little different results, especially on the trials that received the extra shot of nitrogen late.  By R1 corn has roughly taken up 60-65% of its nitrogen requirements for the season, with the remainder being taken up during the grain fill period.  As the corn tassels and moves into the R-stages water requirements triple form about 0.1" of rain per day to 0.3" of moisture per day.  Cloudy days post pollination can result in kernel abortion.  Daytime high temperatures in the upper 70 degree to low 80 degree range with nighttime lows in the mid-60's are the best for maximum yield.  Temperatures warmer than this during daytime or nighttime causes the corn plant to expend carbohydrates made from photosynthesis to regain plant a healthful state.  While current conditions are good moisture and temperature wise, cooler nighttime temperatures would add more bushels yet.

St Aubin Farms Interview7/24/2018

​Sarah Surprenant, Crop Specialist with Heritage FS, located in St. George is working on a 4R4U nitrogen management plot.  ­­­To get a better understanding of the work done for the 4R4U plot, we asked the grower, Greg St. Aubin, a few questions!

1.       Why do you believe that practicing the 4R method is important?

As a farmer and certified crop advisor I appreciate the 4R program for its education and as a practical tool in the toolbox. Soil fertility recommendations from a public source are old and not given as much attention as weeds, diseases, and GMO research. I'm looking forward to putting its concepts to work on my farm.

2.       In what ways outside of the 4R4U program are you practicing the 4R method?

Before adopting the 4R method I have started to side dress my corn and in a few cases split my applications. We are also soil sampling for organic nitrogen and creating VRT maps so we are not over applying. That last practice is being tried for the first time this year.

3.       How would you define success of your nitrogen management plot?

Success for my nitrogen plot would most certainly be achieved by what we learn. And when I say we, I am speaking of the Heritage FS crop specialists. They can help quantify what we see out in the field.

4.       Did you start a new practice through this program?

We are working with nitrogen stabilizers at different rates and timing. This would be a new practice for us if we see benefits.

Crop Update- Herscher, IL6/30/2018

Justin with Heritage FS in Herscher is working on a nitrogen management trial for the 4R4U partnership. This trial is looking at corn-on-corn acres with side dressed nitrogen and Y-Drop nitrogen versus corn-on-soybean acres with side dressed nitrogen and Y-Drop nitrogen.

The corn-on-corn acres were planted April 30th. This plot received 190lbs of nitrogen side dressed in May, and a second nitrogen pass with 40lbs. The corn-soybean rotated acres were planted April 25th. This plot received 150lbs of nitrogen side dressed in May and a second nitrogen pass with 40lbs. This plot also had a section of cereal rye. To date the plots have received 6.1 inches of rain, a maximum temperature of 92 degrees F, a minimum temperature of 62 degrees F, and 1283 GDU's.

Crop Update- St Aubin Farms6/20/2018

Sarah Surprenant, Crop Specialist with Heritage FS, located in St. George is working on a 4R4U nitrogen management plot.  Four miles northeast of Grant Park we are working on a 4R4U plot that is testing the usage of Nitrogen stabilizer throughout the growing season. The 40 acre field is split into three trials. All trials received pre-plant spring ammonia on April 12th, was planted on April 30th, and was side-dressed with ammonia on May 26th. Pre and Post ammonia applications were at a rate of 80lbs/acre.

  • Trial 1: The Control, received no N-Serve pre or post.
  • Trial 2: Received the standard rate of N-Serve pre and no N-Serve was applied at side-dress.
  • Trial 3: Received the standard rate of N-Serve for pre and post applications of ammonia.trial 1 end 2 start.jpg

The crop is being monitored closely and records are being kept via Climate Fieldview. To date the corn is at the V8 growth stage, has received 4.6 inches of rain since planting, and has accumulated 490 GDUs. The crop is not showing any symptoms of nutrient deficiencies and overall looks very healthy.

Our first round of N-watch sampling was before any ammonia was applied and came back with consistent numbers. Our second samples however, came back inconclusive. We have another round of samples scheduled to be pulled at tassel.

Thanks to Greg St Aubin for working on this 4R4U nitrogen management trial.

Crop Update- Abbott Farms6/18/2018

Chase Aylesworth, Crop Specialist with Heritage FS, located in St. George is working on a 4R4U nitrogen management plot. This nitrogen management plot is looking at four different rates of nitrogen and timings of application.  All four treatments received 25lbs of nitrogen at planting.

  • Treatment 1: Pre-plant 185lbs nitrogen
  • Treatment 2: Pre-plant 145lbs nitrogen followed by an additional 50lbs of nitrogen
  • Treatment 3: Pre-plant 75lbs nitrogen and followed by an additional 120lbs of nitrogen
  • Treatment 4: Pre-plant 185lbs nitrogenAbbott Farm.jpg

Chase writes, "The 4R4U plot is coming along very well, and over the past couple weeks has received some very crucial rainfall.  Soon, for the studies that require it, we will be making our third pass of nitrogen.  We have pulled the initial N-Watch samples and are going to continue monitoring nitrogen levels throughout the season. The plot is enrolled in a crop health imagery program, where we will receive crop health images of the field taken by a plane.  The first flight is scheduled for early to mid-June.  We look forward to continue learning and watching progress throughout the year."

Thank you to Clay Abbott for working on this nitrogen management plot.
