4R4U project subsites

4R4U Project Header Image

M&M Service Co. and the Macoupin County Farm Bureau are teaming up to demonstrate the impact of implementing 4R nutrient stewardship practices.  A DTN weather station will help gather tangible data on the project that will focus on cover crops at two different locations (with two different soil types).  The increased efficiency of applied nutrients in addition to the ability of cover crops to sequester nutrients left over from previous crops will also be part of the project.

  
  
June Crop Update6/23/2018

Clark Vanbuskirk, Area Manager with M&M Service Company, is working on a 4R4U nitrogen management plot in Carlinville. The nitrogen management study is looking at three different rates and timings of nitrogen applications.

  • Treatment 1: 180lbs nitrogen sidedress
  • Treatment 2: 120lbs nitrogen sidedress and 60lbs 28% post applied by Y-Drop
  • Treatment 3: 180lbs nitrogen pre-plant4R4U PIC 2.JPG

DTN weather station data:

  • Highest Temperature:  (°F)    92.0 
  • Lowest Temperature:  (°F)    55.0 
  • Growing Degree Days:   575 
  • Total Precipitation:  (in.)    3.42 

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.

Weather Overview for June7/1/2017

​For the month of June average high temperature was 84.1 degrees while the average low daily temperature was 62.7 degrees.  The first 2 weeks of June saw trace amounts of perception recorded while averaging 86.7 degree under windy conditions.  Some rainfall did occur in later half of June with the highest daily total of 1.39 inches falling on the 18th.  Monthly rainfall was below average with a total at the site was 2.78 inches compared to 4.52 inches the previous month.  Growing Degree Units (GDU) accumulated was 684 with the highest daily amount recorded on the 13th at 29.  Evapotranspiration for the month totaled 6.73 inches leaving a shortfall of 3.95 inches compared to precipitation.

Evapotranspiration (ET) is the sum of evaporation and plant transpiration. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.

Weather Overview for May6/1/2017

​Following a low of 44 degrees on May 1st, ambient temperature rose steadily to reach a high of 87 degrees on May 18th before a cold front that brought more moisture into the region.  Average air high temperature was 74.4 degrees while the average low daily temperature was 54.9 degrees.  Average daily soil temperatures peaked at 66 degrees several times throughout the month with the last 23 days of the month maintaining soils above 60 degrees.  Monthly rainfall total at the site was 4.52 inches with the highest daily amount or 1.19 inches on May 20th. Drier weather patterns were seen in mid and late May which allowed for field work to make progress.   For the month a total 456 Growing Degree Units (GDU) were received with the highest daily amount recorded on the 18th at 28.​

Weather Overview for April5/5/2017

​The first 3 weeks of April saw warm air and soil temps that was conducive to early planting but was followed by rain and cooler temps during the last week.  A high of 85 degrees was recorded on April 19 while the lowest of 36 degrees was recorded on April 7.  For the month of April, a total 331 Growing Degree Units (GDU) were received with the highest daily amount recorded on April 15 at 23 (GDU).  Average daily soil temperatures peaked on April 20 at 61 degrees with a low of 52 degrees on April 8.  The average soil temperature for the month was 56.1 degrees.  Following a warmer than normal winter, soils maintained 50 degrees or higher every day in April which would have stimulated microbial activity converting ammonium nitrogen to nitrate.  Monthly rainfall total at the site was 6.78" with 5.1" of that total coming during the last 5 days of the month. Saturated field conditions along with a high percentage of nitrogen in the nitrate form may have increased the potential for denitrification and leaching.
