4R4U project subsites

​​​4R4U Project Header Image

Gold Star FS and the Mercer County Farm Bureau are teaming up to demonstrate the impact of implementing 4R nutrient stewardship practices by gathering tangible data on nutrient management practices such as split N application.  A DTN weather station and N-WATCH soil sampling sites will be part of the information gathering process on practices that will include side by side comparison of cover crops while analyzing the corn growth and development.

  
  
Interview with Chad Bell7/30/2018

To get a better understanding of the work done for the 4R4U plot, we asked the grower, Chad Bell, a few questions.

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

    The 4R method is important because it means that we are applying nitrogen in the most environmentally responsible method. 
  2. In what ways outside of the 4R4U program are you practicing the 4R method?

    I am split applying nitrogen on 100% of my corn acres, as well as using urease and nitrification inhibitors.  I have moved all of my N applications to spring. 
  3. What is a benefit you have found using the 4R method?

    I have found that the nutrient use efficiency has been very high the last couple years. My lbs of applied N/bu of corn produced has been 0.6-0.8 on average.
  4. How would you define success of your nitrogen management plot?

    Success would be to find that the least amount of lbs of applied N/bu produced is the most economical. Maybe we are producing 300 bushel corn on 150 lbs of applied N instead of 200 bushel corn on 200 lbs of N. 
  5. Did you start a new practice through this program?

    I have been doing a little soil nitrate testing off and on when weather conditions are conducive to N loss but it hasn't become part of my typical N management program.

Interview with Bryce Holmes7/29/2018

To get a better understanding of the work done for the 4R4U plot, we asked the grower, Bryce Holmes, a few questions.

1.      Why do you believe that practicing the 4R method is important?
Practicing the 4R4U method is important in reducing nutrient run off into our waterways.

2.      In what ways outside of the 4R4U program are you practicing the 4R method?
We've been practicing variable rate fertilizer both in the fall and when we sidedress.

3.       How would you define success of your nitrogen management plot?
To me success in the nitrogen management plot is finding what works best for creating the highest yield in a cost effective manner while protecting against any nutrient runoff.

June Crop Update6/25/2018

Gold Star FS is working on two 4R4U nitrogen management plots. The nitrogen management study is looking at three different rates and timings of nitrogen applications.

Plot 1 with Bryce Holmes:

  • Treatment 1: Manure and Instinct
  • Treatment 2: Just Manure
  • Treatment 3: 32%

 

Climate FieldView Weather Data:

  • Highest Temperature: 93.0 (°F)
  • Lowest Temperature: 51.0  (°F)
  • Growing Degree Days: 528
  • Total Precipitation: 4.31 (in.)

Plot 2 with Chad Bell:

                                     32% UAN             Super U 5-25-18

  • Treatment 1 –    184 lbs/N             0 lbs/N
  • Treatment 2 –    138  lbs/N            46 lbs/N
  • Treatment 3 –    92 lbs/N               74 lbs/N
  • Treatment 4 –    74 lbs/N               92 lbs/N
  • Treatment 5 –    46 lbs/N               138 lbs/N

Climate FieldView Weather Data:

  • Highest Temperature: 94.0 (°F)
  • Lowest Temperature: 50.0 (°F)
  • Growing Degree Days: 572
  • Total Precipitation: 4.09 (in.)

The crop is being monitored closely and records are being kept via Climate Fieldview. The first nitrogen soil samples have been pulled and another set of soil samples will be pulled at VT. Next steps are to monitor the plots through crop scouting and drone imagery.
