Zach Collins, Sales Intern, under leadership of Todd Wibben, Crop Specialist, with Evergreen FS, located in Forsyth is working on two 4R4U nitrogen management plots. This nitrogen management plot is looking at timing and rates of nitrogen applications.
Plot 1: 3 nitrogen passes
Plot 2: 2 nitrogen passes
Evergreen has taken tissue samples at the corn crop V4 and soil nitrogen samples. To date the corn is at the VT growth stage, plot 1 has received 4.1 inches of rain and accumulated 1198 GDUs and plot 2 has received 4.5 inches since planting and has accumulated 1205 GDUs. The next steps for the plots are to monitor it from Climate FieldView software, complete crop health imagery, and take soil nitrogen samples at VT.

July saw average rainfall through the month with a total of 4.15 inches for the month. The highest daily amount was 2.41 on the 11th which was the only rain event over an inch for the month. A total 749 Growing Degree Units (GDU) were received with the highest daily amount recorded of 31 recorded on 21st.
June saw a stark contrast in weather conditions from the previous two months with unseasonably warm and dry weather. For the month average high temperature was 84.4 degrees while the average low daily temperature was 63.7 degrees. The first 2 weeks of June saw zero perception recorded while averaging 87.5 degree under windy conditions. Some rainfall did occur in later half of June however; monthly rainfall total at the site was 1.51 inches compared to 5.92 inches the previous month. Growing Degree Units (GDU) accumulated was 698 with the highest daily amount recorded on the 13th at 31. Evapotranspiration for the month totaled 7.45 inches leaving a shortfall of 5.94 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.
The first 3 weeks of May saw air and soil temps fluctuations of 37 and 16 degree respectively. May 1st saw the lowest temperature recorded at 39 degree with the high of 88 degrees being recorded on May 18th. For the month a total 428 Growing Degree Units (GDU) were received with the highest daily amount recorded on the 18th at 26(GDU). Average daily soil temperature peaked on May 30th at 72 degrees with a low of 51 degrees on May 4th. The average soil temperature for the month was 63.7 degrees.
